Transforming Service Provider Networks Through AI-Powered Connectivity

uh today we made a you know big announcement on the agile Services networking which is a New Concept that we are introducing for the new AI era on the traic growth and managing the service provider networks and Beyond So today we're going to be speaking actually like you know three different topics we have three speakers in the room first of first of all I'm going to be describing like you know uh why we are doing what we do on the agil Services Network and I have two colleagues with me um Phil and and Brian they're going to be describing like what is in it and you know which customers and you know how the customers are implementing actually that solution okay so three agenda points so let's start you know why now and what we do now uh in in general okay what when we see the traffic and when we see the service provider Evolution and the networking Evolution actually like we see AI is really impacting uh how the traffic mix is is changing in the network implementations right so as of today like 30% of the traffic is driven by the AI and we already see the evidences in the data center interconnect and the edge to network actually flowing uh increased data rates with you know 30 35% in the networking so that's really like a mix of traffic which we are not seeing which we were not seeing earlier in the service provider networks which is actually triggering a new thought like how we going to address the growth right in this one so by the introduction of like you know C GPT in 2022 now in two years we are seeing like you know a huge adoption which is 65% of the you know the traffic has been um you know produced in the edge uh data centers or in the edge of the locations uh let's say and then like we're also seeing like you know up to you know 65% of the organization using AI for the generation of the traffic and the content right uh that trend is expected to grow and by 2020 2030 we are expecting a huge growth like you know 120% uh Euro increase in the traffic and the traffic metrics like you know interconnecting each sites right so like the big question becomes like how are we going to address that growth and how are we going to address that adoption right you can see like three problems uh on the space like first of all as we described increased traffic on you know triggered by the AI and that bandwidth cannot be accommodated actually in the networking layers if you have a suboptimal transport which is in today's architectures right so that will result in redundant Investments that will result in like you know a suboptimal slas in the service introduction so like you know that needs to be solved that's problem number one that we are solving with the agile Services networking problem number two is that like the most of the service providers needs to innovate and introduce new services so that they they can generate like free revenue and they can generate actually margins however with today's like you know constraint scalability and like let's say um squeeze margin that they have it's not easy to actually innovate like using 20 years of architectures and 20 years of you know suboptimal products right uh in the network so that's the second piece that we are trying to Sol with the agile Services networking and of course like you know the the changing in the traffic patterns as I tried to explain earlier uh it's a different traffic Ms now it's edge to edge but Edge is supposed to be anywhere by the you know by by the customers and whoever is using this one so like you know we need to introduce the anchoring points into the networks where you can actually float the edge in as a as a function from starting from the access to the aggregation to the central of the networks without you know having any compromise to interconnect any endpoint right to each other so this is the third point that we're going to address with the agile Services networking and let me actually describe how we going to do that like how are we going to solve this problem uh by addressing like you know with three key pillars right our first pillar is actually uh intelligent aggregation intelligent distribution so what it really means is that we need to push the edge as much as possible to the end user who is consuming it right it means like earlier handoff of the traffic to the possible clouds to the possible end point so pushing the you know the anchoring Point as much as possible to you know closer to the anend user right that's going to give us like you know an efficient service you know delivery and we can we with be able to interconnect any end point without actually making a troling in the traffic so like east to west and you know south to North will be optimized by the traffic deliveries as well um this is going to provide us a network Centric actually resiliency in the networking because now like we're going to have maybe a smaller edges or smaller anchoring points for all the interconnectivity types which is going to you know come up with you know reduced blast radius in terms of failures and easy management of the traffic you know while we are uh interconnecting the the SES right so that's the first point the second point I'm going to discuss with the assured convergence right in order to achieve this you know agile Services networking connectivity model you need to have Edge anywhere first of all right so that's really a convergence of like traditionally known access aggregation and Edge domains all you know in in in a conjunction right uh the hard point is like when you push push the edge with this you know current architectures of the products and you know the services like to the access that becomes too painful to accommodate the cost level right so you need to address in a different way like how much scale that you would be accommodating and how much capacity you need to accommodate in these different locations you know selectively so it's going to come with you know multi-layer convergence in the systems and in the architectures like first convergence layer we will be talking about you know the convergence of the residential and the Business services so we would like to have a common architecture common product portfolio and common delivery architecture for the Automation and you know the assured you know network operations to accommodate you know both residential and both business Services all together the second piece is going to come with the infrastructure convergence we are already doing this one rou Optical network is a great example but we are converging different you know technological layers in the networking like IP Optics uh passive Optical networking all in a Comm infrastructure which we can actually do any service or any access point any access type into the networking the third point of the convergence that's going to come with Wireline and wireless convergence which is also going to be addressed like you know the Mobility Services plus you know the residential subscriber services so that common infrastructure will be serving to any access types for you know starting from the mobility and ending in you know the regular normal you know home users as well right so that's that's our second pillar uh to serve the networking having a converge architecture and converge system which we can serve any access so how do we achieve this in the end is actually with the resilient simplification that's that's what we call right this is driven by the carbon silicon architecture which means that across the portfolio for the pins that we're going to deploy in Access in aggregation in Edge and in core we're going to have a unified silicon portfolio uni unified silicon one portfolio which we can actually unify the services just by trading in and trading off like the scale and the capacity across the layers right which is a huge Advantage like customers when they need a higher scale they can actually trade this with the capacity or they need higher capacity they can trade this with you know the lower scale as well right that's number one the second piece is that the unification of the transport Phil is going to describe like you know more details on this one but that's going to be a common protocol layer on the transport so we will be unifying the service delivery architecture here uh the third place is that we are innovating in the subscriber management side of things that comes with you know the functional desegregation as well so like this new architecture will be served by the cops architecture on the b& cops architecture from the mobility side as well so we're going to have a common control plane which is actually talking to our automation systems and which are unifying the service delivery for subscriber Management in the usual planes area and that's all going to be connecting with the overlay business services including sdent as well right so these are the three key pillars uh which will be addressed within the edile services and now I would like to actually deliver the word to my friend colleague Phil uh to describe what is in it actually and how we do that yeah kind of what is it uh so agile Services networking it's an architecture it's a solution there's a lot of different components to it uh that make up what we call this ENT solution ENT architecture and I'm just going to touch upon a few of those today because spend a whole kind of 4our session going into a deep dive of that but I'll really just cover the basics and kind of the basic blueprint of what it is how it works and how we're enabling you know connectivity I said AI is is potentially a big traffic driver on networks uh in the future but we're really covering any kind of operator service so the idea is not just Ai and the things that are coming but all the things that uh you know providers are doing today and how we simplify those again it's about creating any any Services uh it's about taking away maybe silos of the network where in the past we might have had an Access Network a Metro Network a core network uh and really being able to satisfy any service needs on at any point no matter where it is in the network uh the other idea is taking away potentially like you know platform invitations and having to use specific platforms specific parts of the network it's really about being able to deliver those Services across a single consistent uh set of Hardware end to end across the network uh so again all these different service types over a single converge Network I think that's one of the key points Mustafa touched upon is Convergence both on the network side and I'll talk a little bit about how we're also doing convergence on the even the the device side where we can do more within a single device to allow you to simplify the network remove devices remove protocols uh you know over time uh it's really about simplification I think something we've kind of touched upon a lot in the past is really Network simplification that's really the key to to networks that are easier to operate and easier to manage over time um I know I just said the word simplification but again it's all about simplifying networks uh so service optimization uh one of the key tenants and I'll talk a little bit more about this is like segment routing so obviously Cisco and segment routing kind of go hand inand they have for for a number of years uh but when you look at the actual kind of foring plane control plane of the networks that operators are building today uh any new network today is is built using segment routing uh it's a way to simplify the network you're removing protocols from the network uh you're enhancing you know services with the network uh and you're adding capabilities for things like traffic engineering uh the ability to assure the network and I'll talk a little bit about that is all enhanced by using segment routing so it's really the building block that we use to build these I don't want say next Generation networks uh and it's really the foundation of what we're doing with agile Services networking from a control plane boing plane point of view uh again we talk about device convergence and it's the ability to do more functions within that single device we' talked about routed Optical networking now for almost 5 years and that's you know the convergence of Ip and Optical on a single device and eliminating a layer of the network and and extra Hardware that you no longer need uh we're doing the same things with like Pawn uh so we have a routed Pawn solution very similar we're able to do things like put an ALT within the device now I don't have to have that extra Hardware sitting outside uh in the network um and we're also doing a thing with those things with security uh so I'll talk a little bit about dos so being able to distribute dos protection to any part of the network so we're able to really do DOS detection and mitigation on any router in the network uh which is a little bit different than architectures that are currently deployed where I might have centralized detection I might have centralized scrubbing and we'll move away from that and really you know distribute these functions throughout the network and they can really be deployed anywhere in the network I think that's one key Point Mustafa made was was distribution of of services and distribution of these Advanced functionalities over time we'll talk about silicon one um and these are all things that silicon one is a big part of I think the the launch messaging and and the keynote today is really extending what we've done with silicon one over the last you know six or seven years which is mostly focused on really high bandwidth uh applications and enhancing those chips enhancing you know that line of Hardware to serve more Edge functionality so it's really now we have this kind of endtoend unified story with silicon one all the way from the access uh to highspeed core interfaces I said that's sort of a key thing that you'll you'll see as you know new hardware comes out and I'll I'll talk a little bit about a couple of the devices that are are coming out uh just now and in the near future that kind of satisfy those um we won't go through this whole slide but really it is about taking you know what you saw in a lot of Legacy networks uh the way they're built with you know kind of the laundry list of protocols for doing things like npls label distribution uh we eliminate a lot of that with segment routing uh so we simplify the network segment routing just uses the igp to distribute uh additional you know MLS label information or srv6 can even simplify that even more it's really about eliminating all those layers of the network uh and simplifying that but then we take that to things like the sort of transition from IP to dwdm that's where routed Optical networking comes into play uh so we're eliminating a whole layer of this sort of optical electrical to Optical transition and shrinking that into a plugable optic uh so a big part of the launch today was additional coherent Optics that we're going to use to enable longer reach bner gig as well as 800 gig uh just an a plugable optic that plugs into a whole set of routers that we offer so again it's about simplifying layers of the network eliminating duplicate hardware and again doing the same thing with uh there something we call private line emulation which the traditional otn networks that carry fiber channel otn sonnet Services now we can do the same type of function uh within Hardware on a router um so it's really about enabling the network to carry uh you know Services even non IP Services um so we have that single converged IP network now they can carry you know services that are not just even ethernet and IP they can carry fiber channel transparently over the network so again it's all about eliminating layers and simplifying that overall architecture I have a question on this slide sure so so you know there's plenty of like you know Cisco uh terms in there so you know how much is in terms of the interoperability between the different vendors like you know there's obviously like on the left side there are some like you know uh standards on the right side are these standards yeah so when we talk about rotted Optical networking it's plugable coherent Optics and those are absolutely driven by standards oif or open ZR plus and we've been doing interop events now for for years with that and we're the only ones offering from other vendors you might hear it called coherent routing something similar to that uh lots of interop there uh like I said it's really plugable dco ZR ZR plus Optics uh highly interoperable there uh private line emulation there's some things we're doing there on the interop side right now that's a pretty unique Cisco solution you'll see at events like ofc that's coming up uh in a couple months uh you'll see that we'll be doing an interrupt there with private line emulation as well uh and the the standards that drive that uh there's some Hardware stuff there that's a little more secret sauce from a circuit emulation but all the control plane standards are all being driven through the ITF and they're all multivendor okay so so certain features will be probably supported only if you will be Cisco to Cisco yeah some of them like the private there's some Innovation we have there that we just happen to come out with first uh but we do see others that are looking at that and again the control plane of that is all standardized okay it's EPN based it's uh you know exactly there's some additions we're making to it but we're making sure that it's not just a Cisco only thing it's there's a whole ecosystem around it perfect yeah thank you so I'll talk just a little bit a few slides about individual kind of Innovations I touched upon these earlier and Mustafa also touched upon them as well uh again you know Cisco 8000 silicon one and extending that family to you know satisfy more use cases uh is a pretty ke tenant of agile Services networking and that's something we'll just continue to build on over time with that uh that forf and again extending coherent Optics uh I said routed Optical networking has been very successful in in collapsing those layers but being able to you know address more use cases with longer Hall Optics uh and also with 800 gig so 800 gig is kind of the next evolution of those coherent Optics and being able to carry uh do 800 gig single wavelength over uh you know traditional dwm systems um but then you know we talked about hardware and a lot of those things and convergence but also the Automation and the management software that goes with it uh so when we talk about agile Services networking it's not just about the hardware it's about the software that manages the network as well um and that involves the last two bullet points there um crosswork Network automation that's the the brand name we have for our you know family of management software that manages uh these higher scale SP IP networks um and you'll see provider connectivity Assurance um I'll say formally a cian so it's taking you know what they did in terms of to do monitoring and Assurance uh with sensors at a very large scale uh and you know pipelining that data uh into their systems collecting it doing alerting uh but then obviously with spunk we have the ability to even you know do further integration between you know provider contivity Assurance in Splunk to to add even more sort of I'll call it you know business data into what we're doing with the data that's coming from PCA and from the network uh and we really look at the network as a sensor uh I won't talk too much about this today but segment routing has a wealth of different things we can do to monitor paths in the network we can monitor latency and loss uh we feed that Upstream into tools like PCA where that you know data can be aggregated it can be viewed it can be monitored uh and then we can also you know do additional learning on that uh and from there it can go into systems like Splunk or integrate into other systems so you could do get more sort of business value out of that data that you're getting from the network uh so it's really about being able to do the Ed monitoring assurance uh for the new infrastructure that we're building and sort of new applications that we're going to have to so this assumes that actually you would have the P computation element and collecting all the data and then filling into spunks so that you can get some intelligence out of it yeah potentially yeah uh like I said that's where we probably would have put this sort of the PCA collector in front of that too to get another level of aggregation and sort of data enrichment uh and then yeah that would go into Splunk you know and then potentially I said be combined with sort of business data uh even more metadata so yeah the idea is yeah yeah that data whether it's a PC or some type of other sensor that's built into the network all that data flows Upstream um yeah and so so is there any you know Vision what we've seen this morning of the Keynotes with the dpus and stuff like is there any sort of a vision of you know looking at that for the service provider world uh I'll say we're definitely looking at it okay we're not enough no commitment but the that that was on the Nexus side of things exactly yeah yeah but no definitely looking at for for applications that require uh more advanced packet handling things that just aren't really that doable today in highspeed npus but yeah absolutely looking at those because they would be like you know in line what you were saying at the beginning right like stream lining everything you're doing end to endend so using same same architecture I guess right yeah yeah like I said there's definitely a high touch packet handling functions that are are better suited for a dpu than Network Processing Unit so we're definitely looking at those types of applic it does seem like a way to go though because anyway the moment you're unifying the infrastructure indicates of router Optical n working they got rid of the device that was doing then the serialization between internet and the optical network but once you get out of the way then what are going to what are you going to do to optimize pocket handling serialization delay and all those things that you can beat with simple physics you can you have to get a bit more creative but then but the moment you simplify it and it's in everything is des all the way from the until the end of the netork then it does make sense that then they would apply all the power that silicon warm would have because then if everybody has it then what's the point of not making use of it yeah but probably it's a bit early but if it's a Nexus it will eventually land on some other product yeah so Nexus maybe leveraging that for advanced you know security you know purposes and there's other SP things that we could potentially do with that that dpu and again like you said it's about eliminating extra boxes in the network that have specialized functions and being able to combine those into a single single device just to minimize footprint minimize you know management of that like a subscriber management Etc right you know using the dpus for that yeah I mean you can think of applications like Nat things like that that you know modern high speed npus are not great at doing but you know those are applications me those are things that we're we're looking at sort of for the future and and those types of applications um this is just an example of some of the newer devices that we're releasing like I said you see most of the AK your silicon 1 8000 based series devices today are highp speed you know up to 25.6 terabits and a a single fixed platform U but these new platforms are modular they're a little bit lower bandwidth uh but they're meant for Edge services so there's things like Edge service scale that's quite a bit higher on these devices um and then we'll have you know traditional what we call Access like I said we don't really want to you know pigeon hole these as access and Edge the idea is to support a common feature set across all these devices um so today you might pick a specific platform just because that platform you know supports feature X another platform that's a higher speed platform you know doesn't support that feature the idea is really to only pick a platform I think Musta said based on the bandwidth needs you have and potentially the port speeds you and not so much the Chip And you know a specific device for a specific place in the network so again you know these are a couple of the new uh you know systems and the K100 processor is the newer processor that we have on the silic one side focused on edge the a100 is a lower speed processor but it's focused on Lower speed applications that are usually kind of the the access and in very far aggregation parts of the network but again it's a single architecture with silicon one end to endend and the idea is to be able to deliver these features ubiquitously across all of those different devices no matter where they're at the network uh and I've got a couple slides just on like routed Optical networking uh like I said this isn't new we we talked about I think at Tech field day over four or five years ago now uh and it's really about taking you see on the left is all these layers of the network potentially shrinking those down it's eliminating and you can kind of see the simplification story there traditionally in these networks the way they were built uh the DDM networks and things like that you have a transponders you have a lot of gray Optics you have to interconnect to all of that uh We Shrunk that all into a plugable you know and that's I said that was done you know five years ago and we're continuing to evolve that over time time to increase the speeds and capabilities and lower the power that those Optics use uh so when you look at Cisco devices today and these are you qsfp DD Optics uh they are shipping today but pretty soon we'll also offer these in a qsfp 28 100 Gig form factor which really unlocks a lot of applications for uh for more devices that the ability to use routed Optical networking um it's something that just makes sense you know today we have over 200 customers that have this deployed just because it's uh I call it kind of a no-brainer technology it's just something that you're eliminating your devices in the network you're eliminating complexity uh and it's you know cost- effective and it's from a both capex and Opex perspective and uh Brian will talk a little bit about that and some of the customers that we have uh have deployed this at larger scale today uh and again the Optics that we've used for routed Optical to date they're 400 gig Optics but they support multiple speeds but they do require like a qsfb DD Port which limits some of the the reach ility and deployment of those uh those Optics uh so very soon we'll release a qsb 28 100 Gig ZR which is a tunable dwdm uh you know 100 Gig optic that's in a qsb 28 form factor uh it's always been the the limiting you know factor with that has always been power like qsv 28 ports were always meant to be very low power ports about five Watts uh a 400 gig ZR optic is around you know 20 to 23 Watts so you can't really support that in a q speed 28 Port uh but you know technology continues to advance and we've Shrunk the power usage of the chips that drive the dwdm to a you know within a 100 Gig speed uh to something that's less than five Watts um so these are great for Access Rings aggregation Rings things like that or even pointto Point dark fiber applications uh where now I have a tunable 100 Gig uh gby 28 optic um and then on the high-end side we're continuing to advance what we're doing in in DD and 800 gig so 400 gig ulh takes the reach from a 400 gig you know coherent optic which is about 1300 kilometers and the current shipping you know sort of version of that to now something that exceeds 3,000 kilometers so some of the really long haul applications that we couldn't reach at 400 gig you know in the past few years uh those are going to sort of go away now as we have ulh Optics that have a much longer reach uh and those will be supported across all the devices that we support 400 gig with today um and then 800 gig zrzr plus uh we're starting to see you know more interest in that uh we recently did a couple of press releases with uh you know two carriers in Europe that have tested 800 gig ZR uh and it's really about these high bandwidth interconnectivity things like DCI uh where we're addressing those needs with 800 ZR and 800 ZR plus obviously the reach is not going to be quite as long with 800 gig but you know it's very high bandwith applications um and those are things that are coming you know middle of next year or middle of this year I guess 2025 like I said we'll continue to evolve Optics over time and we're you now looking at the the next generation of those Beyond 800 gig uh I mentioned segment rounding is a foundation for how we kind of if you take the layer above sort of the the infrastructure piece of the network and how we address you know how packets are carried over the the new infrastructure segment routing is really the base of that um people typically ask you we have two flavors of forwarding planes with segment routing it's really the same architecture with two different forwarding planes there's srmls which is now been around for quite some time and it's pretty widely supported across the the vendor Community srv6 is the IPv6 variant of that uh and it really takes what we've done with srms and it it simplifies it even more uh you're really just doing IP routing uh you get all the same capabil you get with the mpls uh forwarding planes uh just simplify with with IP uh we can do things like aggregation of space you think of Trad traditional IPM PLS networks uh you have to have a loop back address like a sl32 that has to be reachable from every other part of the network you can't really aggregate that very well so you still have to distribute a lot of routing information end to end uh with srv6 I can use aggregation so I can have one part of the network that's all behind like a48 aggregate route it's and I don't lose any of the same kind of te capab ities so there's ways that we could still do uh you know end to end traffic engineering but a network that might have been you know 50,000 you know bgpu routes I can now simplify to you know 40 IPv6 you know routes really as many regions as you have you can simplify the networks so we've seen very large networks uh where if you look at the blueprint of how those are built srv6 have very little routing information and the less State the less routes the less scale you have to deal with it makes the networks much simpler to operate uh you can use things like Tracer out if you a VPN uh service is really just an IPv6 address uh it's a constructed IPv6 address but you can trace route to your VPN service I don't have to look at a stack of labels for a service anymore I can just simply look at a V6 address and know exactly which service that uh that's going to it also allows us to do things with you know Network programability that we weren't quite able to do with uh with Ms just based on the scale that it uh uh it gives us over time so one thing we're doing you know with Sr and there's a lot of Sr Innovations I just picked one to highlight today is something that we call Integrated performance measurement It's a combination of things we're doing with Hardware as well as you know Sr and srv6 uh software but it's really you can call it IP performance measurement this all just operates on the IP layer uh but it it gives us the ability to you know from a hardware node to measure every path across the entire network uh at high scale and we report back on this so you know the question I I kind of proposed earlier we've you know used the really the network as an assurance sensor uh in this case we can get the data from every path in the network between any two nodes on the network continuously uh and You' be able to report that into the tools that we have on the automation side like PCA uh and like crosswork um so it gives you a lot of data in order to you know provide Assurance to the whole network this is monitoring the underlying infrastructure but then I can add service layer data to that as well in order to you know correlate between the service layer of the network to the underlay part of the network uh but in some of the neuro Hardware we could set these probes as fast as you know 12 million probes per second I'm not sure you would do that in a production network but it gives us ability to measure ecmp paths up to you know 128 ways if we wanted continuously and again you have to get the the data out of the network but the the data is there in order for us to you know do more actionable uh you know correlation and Assurance than we really could ever do before so again that's just one Innovation that we're doing with Sr uh with in addition it's like measure the latency per link latency loss measurements within the network and that all gets sped into external systems that we then use to correlate that data to the services that are carried over the network um I think we mentioned a couple times around like device convergence uh we look at you know today we have kind of many different components that maybe sit you know outside the router whether it's a transponder a pwnt otn devices D DDM systems we talked a lot about routed Optical networking and that's a pretty simple example of shrinking that into a plugable but again with Technologies like routed Pond we're able to do the same thing with an Olt that's doing xgs Pond services so I might have a router that's deployed somewhere on the network that's doing business services whether they're fiber based or or some other type of uh Business Service aggregation uh now I can also offer you know Pawn endpoints off of that as well uh versus having to deploy a different ol device which is what's typically done today um so that we call that kind of device convergence it's really being able to combine that uh the other thing that we leverage more and more today is the ability to do application hosting on the router uh so we can host thirdparty applications and one that we're you know leveraging today does Dos protection I mentioned earlier now that we can distribute dos protection in scrubbing really any router in the network and we're doing that through that thirdparty application hosting infra you know infrastructure that we have that's uh specifically built within iOS XR uh it gives us the ability to not just you know converge the hardware on the network but then also a lot of software functions as well um so again it's that simplification that's really the key part that we're we're looking at with kind of agile Services networking in order to simplify the network and be able to offer these you know different Services everywhere across the network and then as new Services come up it gives us the you know ability to even leverage you know applications that we haven't you know even looked at quite yet to for more advanced functionality one question for that so totally makes sense to condense everything to simplify how is it with a Telemetry from your perspective do you still have differences in the quality of the measurement if you're going over an Optical interface or an normal routed interface or the Telemetry data at the end of the day you have the same quality no matter how the interface is looking like yeah I think the key part is to have like the Telemetry if you're talking about the like so the hardware convergence part of it uh yeah you have to have the same Telemetry that you traditionally had in that other platform you have to replicate that and we've you know yeah gone to Great Links to do that uh so when if you look at routed Optical like there's the the Telemetry that you typically got like an optical transponder we have all the same Telemetry that's on the router for that port on the router same for Pawn so you know there's a wealth of pond data that's available uh and yeah we have to replicate all of that same data on the router I imagine if you let's say normalize all these Telemetry data yeah back in the days we had different Islands yeah and then people needed to compare the different quality of telemetry data if you unify that also makes everything much easier to let's say scrub and then maybe send it to something like Splunk for additional analytics and so on yeah I think that's really important especially on the in most networks that you know service buyer networks are not single vendor they're multivendor uh so like you said that data normalization piece is pretty important when you look at multivendor and you do have to have some system that's going to normalize that data um ideally you have you know models and and that you can use on the devices that are standardized that's not always the case so yeah we still do have to do some type of normalization at some layer in order to get into those higher layer systems yeah absolutely and we do try to use you know open models where we can so when you look at things like the zrzr plus Optics the dcos and routed Optical we you know Implement open config models that are pretty standard across the industry for that function uh and you know support those and try to support the latest versions that we can in order to you know make it less painful for for operators to adjust the data and get it into a system that you know especially when they have multiple vendors involved yeah I talked a little about routed Pawn uh quite simple it's taking you know a pluggable an OT which might have been in a chassis plugging that into an edge device so again there I might have you know evpn type services that for business that are on the same device uh I can then you know leverage the same device for kind of multiple functions point I it it just makes sense versus having to put an O at a remote location or back hul traffic uh via you know transport or some other means to a centralized Loop and these are all components that are part of you know we call Agile Services networking uh like said there's there's more of them we can talk about but the idea is to have all these be part of a seam seamless solution uh we talk about you know secure dos Edge protection that's the distributed dos that i' I've been talking about uh where we run these you know containerized dos functions within the devices uh and we support a couple different use cases one is traditional dos at the edge of the network where you're peering or it's an internet Transit connection um so we can put that secure dos Edge protection container uh in that peering router and it and do the scrubbing right on that router so the detection happens there there is a centralized controller that manages all those functions um it's quite easy to even deploy that centralized controller will deploy the Dos container to the devices automatically um so it's not a lot of you don't have to do a lot of CLI type of things in order to get the container and the application on the the router uh it's all managed centrally uh so if I want to have that type of functionality at one point in the network I can easily deploy that and then that device is ready as a basically a scrubbing agent uh for the whole network um and then also you know protecting internal parts of the network uh so let's say I want to you know I have some customers that I don't really trust so I'll put that type of function on a router that fronts that uh sort of residential part of the network uh that can protect you know uh the rest of the world from my customers it's not just about traffic that's coming into your network it's potentially putting what we call kind of Dos detection and mitigation all around the network so it's both protecting you know your network from some of your users or the rest of the world from your users as well like I said there's a quite an Innovative thing that we've done with with building an the network and eliminating things like centralized scrubbing and centralized uh their detection I have one question to the Dos protection are you doing this more or less based on sources or also on services that you say okay this customer has maybe here DS running this spot is producing traffic on this certain let's say Port we just block that or would it be the whole traffic for a certain Source or destination yeah it could be it can be granular even down to like a uh like a traffic payload so like uh like it's it's a traditional like dos it's a an advanced dos sort of detection engine it's it's not just based on you know volume of traffic there's signatures that are matched so it does I'm not going to call it AI but maybe machine learning type of activity that's being done there to identify those attack flows and it'll deploy as granular of a rule as possible in order to block the traffic so it's not just by Source destination IP so like you know it depends on the attack that's being you know carried out but it's not just going to Black Hole the traffic for that whole that whole customer IP or IP Block it's going to try to do it by Source destination port or even as I said as granular as like a a payload signature yeah so in best case the customer running around somewhere sending large amounts of Dos to a certain Services block but you can still watch Netflix without any problems here ideally if it's you know there's a yeah ideally that that could happen okay you know if you're not filling up all the internets but yeah that's the whole point is because yeah there's critical like businesses get dsed all the time there's critical services that you know and it might just be an amplification attack that's just garbage traffic uh but they have business critical traffic that they still want to get through um so the idea is yeah you don't want to block all of that just the part that I think in the past this was one of the major problem if you block everything and sometimes I don't know you block the IP let's say from a university and you're just not affecting the single user you're affecting the whole business also yeah yeah and that's where we we you know providers had yeah more advanced sort of scrubbing infrastructure that did that you're back calling all the traffic to a scrubber and then you know just peeling off the bad traffic there and then you have to find a way to backhaul that back to the you know this allows you to avoid kind of all of that sort of complex you know clean and dirty type of networking you had to do on both sides of that that function um I talked a little about automation and again you know crosswork automation is our family of of automation products we have something crosswork network controller which is really what we use today as uh you know an n10 management system for the IP layer of the network so whether it's EMS functionality like uh monitoring alarms or software upgrades but then it also has more advanced sort of te capabilities uh in traffic optimization as well so it's a platform and you know I could spend a whole session just talking about crosswork uh but it's really for doing things like you know uh EMS function uh as well as you know service provisioning of the network uh within the family we also have like crosswork planning which is a you know traditional IP network planning software uh for those that are familiar with like Cisco way that's sort of the evolution of Cisco Way is a a new platform called the you know Cisco or crosswork planning uh but then we can also do management you know across both IP and Optical as well we talk about routed Optical uh we have to manage those n10 you know dwdm connections uh we use something called crosswork hierarchical controller to do that where we can manage both the iPay of the network uh and those proba you know D dwm services over that Network as well as the underlying sort of dwm photonic infrastructure so again it's really about anend automation across every part of the network is covered like I said we don't when we come out with this new solution architecture we don't want to leave out how we manage then monitor that Network and crosswork is is kind of how we're doing that so is crossb having on top of all their Sho and functions then is also being able to work as your EC what are all the functions that I included there yeah like I said I don't have a lot of time but the PC is definitely part of it uh so we do have something called srpc which is embedded into the network so for you know basic PC functionality we we use that component of it uh but it is a part of kind of the bigger crosswork family and then for some more advanced PC functionality like when we look at congestion management uh there is a more advanced pce that's built into crosswork that does congestion management and it can do things we call tactical traffic engineering to reroute traffic during congestion periods and that we do use an advanced PC we also have something called circuit style segment routing uh which is a way that you know to maintain things like disjoint paths across the network uh bandwidth reservations another way of saying sorry another way of doing Sr is just that you're not just having these unidirectional tunnels and it just do using the protocol extensions which is wonderful right so it's just the big Ser is having crosswork and I have several modules and each one of them is doing a different thing but it still is the same yeah yeah it's all into the family and the umbrella but there's a lot of different functions within what we call crosswork network controller uh and again some of those PC Advanced PC graphic engineering functions it's just another module within that uh that overall controller ah wonderful thank you uh I talked a little about provider connectivity assurance and like I said call it formly aidian uh and it's really the ability to you know bring in a lot of data uh you know from different sources they talk a lot about network data uh data can really come from anywhere they have a pretty flexible collection you know infrastructure uh and the ability is to aggregate that data get more visibility into the data so there are you know some machine learning things that are being done at that layer of the network and also do alerting based on that data uh and one you know nice thing with that platform is the ability to do things like create dashboards uh to be able to look at all the data in in a meaningful way for you know operations teams that's probably or even customer portals or building those types of things so that's one of the key tenants of you know PCA or provider connectivity Assurance but then also being able to feed that data into other systems like Splunk where you can then do you know more data correlation uh and more kind of call it you know metadata you're adding to that data in order to get more you know business insights out of that um within this like adual Services networking you know there's a bunch of different use cases a few these are just sample use cases where we're building you know dashboards and advanced monitoring with PCA and we're taking in uh in most of these use cases data from different not just the network but even the sdan overlay so in the sdan use case we're taking in data from the network infrastructure we're taking in data from you know Catalyst sdw manager and then we're able to do correlation between those two layers within p CCA I said that's sort of one of the key tenants is to be able to take all this data from say disparate sources in the network combine that together analyze it and alert on it uh in order to be able to you know combine those views that typically providers didn't have before uh and even when we look at routed pwn it's not just looking at say Pon o it's also looking at the overall uh you know Pond landscape as well as the subscriber uh management piece of it this is my last slide before I turn over to Brian real quick uh but what comes out of this like you know we talk a lot a lot about sort of you know agile Services networking uh what comes out of that you know and it's really a we have different use cases that lead to kind of validated solution designs we have our own Labs where we set all of these things up we validate them and then we produce content like solution guides as well as endtoend user guides and implementation guides um so we don't just want to talk about it we want to build a validated design uh and publish that and we've done that before with things like converges and transport which is an architecture we've had in the past uh so we really want to enable providers to have Network blueprints so they can Implement these uh in a repeatable way and it doesn't mean you have to implement everything that we're talking about within the solution uh you can obviously take pieces of that and implement it in the network as needed uh but again it's a it's an important part of what we're producing here is the ability for operators or sc's or people internally and externally to consume these uh different solution architectures uh and Implement them in their networks and with that I'll turn over to Brian who talked a little bit about some customers that are kind of doing just that so I I I think you've seen here you know a lot of the capabilities but it's good to put the reality on it now do we have customers that are actually on this journey and that's important to see it is a journey this isn't something we thought of a few months ago and and so there we do have a number of customers today that we're already been working with for a number of years and hitting their goals and actually as we go forward so if you look here there's there's a number of different ones there are a lot of different areas different segments different parts of the world but if we just briefly look at some of them you've heard already the likes of BT um British Telecom obviously based out of the UK and again you'll see common objectives of what they want to get right you'll hear this word simple you've heard it all over our present ation you'll see it all over we need to get simple secure and the word resilient they're really really and really what they've done with their Global fabric here is really going and achieving that desire of network as a service or Nas as a lot of people refer to it now and again the building blocks upon which you'll see today in our agile Services networking they are key to how they want to go around building Network instances around doing multicloud connectivity offering an SLA visibility and again connecting services to that and that's all part of what we're doing today we're further enhancing how they can develop these Services the likes of bell you'll hear things as well around you know how do we get low latency how do we actually get things like iot connectivity and obviously the road to srv6 and Sr is is very key for them but very key here as well is is removing the complexity reducing the layers they talk about uh you know transponders taking transponders out of the network and coherent Optics it's all about collapsing the layers making it more simple and again you'll see some of these here the likes of OT it's it's very interesting obviously part of the DT daa Telecom Group and Amia you know we talk a lot here again about you know how we we simplify down but even simplifying down subscriber management you'll hear announcements around kind of like control and user plane separation so how how do we get better availability resiliency into the network how we get better visibility how you have better use of Ip resources so there's a lot of different operators and a lot of different segments here but again if we if we actually look and we look specifically at a couple you'll see swisscom here and swisscom most people know is is a tier one operator or Telco in Switzerland have entities in Italy now as well but clearly they are you know a mobile provider IP viid residential and TV and had a number of different networks for to for all these different uh segments over the years but what they actually found is they needed to take that complex fragmented Network infrastructure and make it more simple actually at the same time while making it simple the word you'll hear over and over again is sustainability power reduction and definitely as we go into the world of AI Now power is becoming very very important and in both their goals but their objectives for scaling going forward again very important while they converged the network so they took their parallel networks and you saw a reference to 20 different networks I think that was clarified a lot yesterday with saying really was more 20 different platforms converging them down into a single platform but how do I make it simple how do I make it reliable and streamline and how they actually did that was common common Hardware common silicon one from end to end with a common platform with you know the Optics come from end to end but also we talked about resiliency and digital resiliency which was really key for them so you see even our customer experience how they actually did their cicd continuous integration continuous deployment of software and features as they change that Network so again really using the principles what we've seen agile Services Network the the Innovations they've taken their Network for forward and their Opex in general has reduced by an estimated 40% but as you said the biggest gain they see and talk a lot about 90% reduction in power consumption with massive increases in availability and reliability right across the network if we take another example of someone that's very much on the road and and really kind of doing a lot of innovation in this area is Colt which is is one of the global digital infrastructure providers again Mass kind of reachability over 1300 data centers that they reach over 33,000 buildings they connect but these are probably one of the leaders again in this network as a ser service and really what they achieve by that is how can they have cloudlike consumption of the network how can have the visibility that we've never seen before and that's what they really Prime uh a lot of their capabilities around again getting a lot of other advantages as well so very very clearly they have very very demanding customers they they they really want to get kind of large scale how do we actually get to the the simpler network operations but also getting the balance between you know cost and scalability and simplicity at the same time one of their key key um areas here is that over 80% of all their connections in the core in emia are using Ron rooted Optical networks today and increasing all the time but it's the last two areas here that they cause a lot of differentiation simplified automation programmability you know on demand cloudlike that's where their differentiation but you'll see here and we talked about Cisco provider connectivity assurance that is actually the tooling that gives them the Assurance but also the visibility you know do I offer the service yes I do and here's the visible way to see so they have an absolutely Cutting Edge user dashboard that end users can see what services they are getting so you know enhanced customer control control in increased satisfaction very very scalable very cost efficient on demand and again they're seeing 50% Opex reduction uh in this area already along with as we said 97% again in in energy energy energy use again massive goal for them and then finally just taking another example of someone aelan again based in Amia um you know very much in the the nor but they are you know an internet backbone and and they're they're the're world's number one internet backbone uh at the moment but again how do you get similar um kind of goals and and you'll see a commonality between all these right how do we make it more simple how do we make it cost optimized but highly performant um but then getting the bandwidth to the levels that we need and so a Big Driver here again is the scale of silicon one common common Hardware from end to end you know coherent Optics and being able to go up to 800 gigs is a massive massive driver over longer distances for them um so again the whole Ron networking is a big part but you'll see again the commonality here in the final two pieces again is how do we get that visibility how do we get the Assurance I offer it how do I do the monitoring from end to end but also how do I get that programmability it's all about how do I get the consumption through apis through programmability of the net
