PON — Innovation for Now and the Future

0:05 hello everyone and welcome to this latest webinar from amdia brought to you by informatec

0:11 today's topic is pawn innovation for now in the future

0:17 we will be discussing innovative approaches to bringing pawn into the metro network

0:23 our webinar is co-presented by amdia and our partner juniper networks

0:28 my name is julie kunsler and i'm chief analyst at amdia focusing on broadband access infrastructure i want to thank

0:35 everyone for joining us

0:40 today we are joined by anisha and neil domani product manager with juniper networks and robert damon senior

0:47 consulting sales engineer with juniper networks welcome we are honored to have you with

0:52 us today now let's get things started with the presentation

0:59 and we're going to begin with market trends and i want to spend a few minutes highlighting

1:04 some market trends in the pond equipment market the first

1:10 is looking at measuring pond success pond is the fiber access technology of

1:16 choice we've seen very strong growth in pondequit in the pond equipment market

1:21 there's been deployments by a wide range of operator types including integrated

1:27 fixed only and even mobile only we've seen this in all regions

1:32 china is no longer dominating consumption of the global market as numero numerous operators in europe

1:39 the middle east asia pacific north america south america

1:45 and africa are building fiber access networks using pond in addition there is very strong

1:50 movement to next gen pond and in some regions next gen pond has begun to dominate

1:56 networks next gen pond is supporting traffic growth from residential enterprises and

2:03 ex-hall transport vendors are entering the ecosystem with

2:09 innovative approaches bringing access to existing solutions and strengths such as

2:14 adding access to switching and routing and adding adding pawn features and functions into the bng platforms

2:25 pond has been evolving from what was considered a best efforts technology for fiber to the home

2:32 and fiber to the building to being able to handle very different types of traffic in

2:38 different types of applications it is the underlying technology for what we're calling the unified fiber access

2:46 networks trying to take advantage of that optical distribution network build and using it

2:52 for many different types of applications while not all traffic will be put onto a

2:57 pond network the underlying odn can support different types of customers and

3:02 requirements the rapid adoption of 10g and specifically

3:08 xgs pond 10g symmetrical gpon and the usapun for residential and

3:14 non-residential is attracting new approaches to pond technology and new vendors

3:21 which brings us to juniper networks

3:27 over to you and nisha who will talk about the problems and challenges in the pan system

3:35 thank you julie so as julie mentioned vendors are entering the pawn space and

3:41 next generation pawn is dominating different use cases the important question is why are they

3:46 doing this with the increase of work from home home schooling due to covert the demand for

3:52 high speed services has increased which essentially means that the traffic in metro space is growing fast in

4:00 situations like this the operators are looking for a solution that provide

4:05 increased speeds easy to scale options and efficient parts to access the services

4:11 let us explore the options available for last mile technology option one is ethernet to home which is

4:19 a little complex to deploy option two dsl but operators are looking for a

4:24 little bit of more faster solution three is cable technology

4:30 but the requirement is very different from the cable technology five 5g which is

4:36 work in progress right so essentially i understand the requirement is a nice niche of ethernet home and cable uh

4:45 options from an operator's point of view there is also an increased competition that you see you see a landmark satellite

4:52 offering google fiber entering the space and of course 5g trying to solve this

4:58 problem however i think pawn fits the bill much better

5:03 pawn is simpler to deploy you just need a few splitters and you can now deploy 10g pawn which provides loads of

5:09 bandwidth even before we go into more details of the options which will be covered by

5:15 robert let's take a look at a typical pawn deployment a typical

5:20 pawn deployment has a bunch of onus at the access layer

5:26 connected to a dedicated old shelf which in turn is connected to an aggregation platform and then to a

5:33 subscriber access now there are some challenges here in case of a green field

5:38 you are essentially looking for an economical simple and fast time to market

5:44 and in case of a brown field you want to upgrade from 10 gig to 10 gig from existing g pawn e pawn

5:52 network that is one gig or 2.5 gig if you're looking to do an upgrade from one

5:58 gig or 2.5 to 10k in this scenario what you must you will

6:03 have to do is you will have to upgrade your transport connections ont's or access switches and your old

6:10 shelves you must also scale your old uplink from 10 gig to 100k you must take into

6:15 consideration the power in space calculation and also deal with vendor lock emissions

6:21 in a nutshell in case of a brownfield deployment you must consider an entire end-to-end ecosystem while upgrading

6:29 good news is there is an innovative approach available to avoid all the hassles

6:35 robert will walk us through it in detail robert over to you

6:42 thank you anisha you know the latest innovation in pond has been the collapsing of the optical line terminal

6:48 or the olt into a small form factor pluggable optic this is allowing for the installation

6:54 and router ports making a pond network a direct part of the access layer

6:59 by leveraging advanced silicon processes a complete system on can chip containing the intelligence to bridge xgs or 10 gig

7:07 depon directly to ethernet is contained in an sfp plus optic

7:13 this evolutionary design distributes the olt functionality reducing failure impacts and creating a

7:21 port based scalable model this also serves as a form factor to allow for future growth as 25 gigapawn

7:29 and 50 gig pond become standard and developed in the future

7:34 using the same plugable form factor

7:41 the result is the eliminated of the specialized pawn shelf the optics and the fiber interconnects

7:48 the access router now instead of a single purpose chassis full of line cards this allows pawn

7:55 services to be delivered the same way as direct internet access mobile backhaul or wan services

8:03 a single access device can be used for residential commercial and enterprise applications

8:09 no longer limiting pond to just residential broadband julie i believe you have a question for

8:16 the audience regarding this yes i do so we have one poll question here

8:24 which is are you using or are you considering the use of pawn infrastructure for

8:29 non-residential customers um or applications so we'd really appreciate your answer to this poll

8:35 question and we'll have the answers in just a couple of seconds here

8:49 wow so this is uh this is great news in at least in my opinion

8:54 as an analyst that we are seeing that everyone in the audience is either using pawn for

9:00 non-residential or at least considering it um so robert back to you

9:08 thank you julia yeah interesting response on that and remind the audience just to if you do have questions please

9:13 submit them and yes looking at that as far as being able to do non-residential applications

9:19 having a modular design really will play and to be able to have put pawn in places that you haven't before

9:26 you know when we compare this model modular olt to traditional pond deployments we see several advantages

9:34 by creating this open environment the all or nothing model with a single vendor or technology is eliminated

9:41 this gives you the ability to rapidly build a best debris design with the right onu deployment for the right

9:46 service um so can you can i stop you for one second here and

9:52 can you expand a little bit regarding easing into pon you know this seems important especially for network

9:59 operators that have previously focused on active ethernet

10:05 sure julie you know and this modular design allows for an easier deployment upon to the network by

10:10 by simply just adding this sfp olt to an existing router port

10:15 services can be quickly deployed as market demands arise even if there are current slower speed

10:21 pawn deployments the module olt allows for a 10 gig pond to be added without

10:26 network wide upgrades as a result you'll be quickly able to

10:32 quickly deploy pawn equipment avoid or eliminate specialized hardware

10:37 saving precious space or power and deploy more services no matter what the less mild technology is used

10:44 when you compare 10 gig pond to one gig active ethernet you can immediately see the benefits and saved ports having a

10:52 design that allows you to deploy pawn alongside of the active ethernet deployment on the same platform also

10:58 gives the operator even greater flexibility but can we focus for a moment on power

11:06 because there's tremendous focus on carbon neutral you know historically regulators have really focused on

11:13 the con the customer promise side right bringing down or encouraging operators to lower

11:19 the power consumption of devices in the home because after all the regulators are really there to protect the the

11:26 subscriber the consumer so i'm interested if you can elaborate a little bit more

11:32 on how your approach helps to bring down energy usage

11:38 that's a great point julia and you know power consumption has become a forefront in network design

11:44 you know newer devices have greatly reduced the power per gigabit when you eliminate it you know

11:51 in the equipment you know with the faster speed equipment with the newer designs but when you eliminate the

11:57 additional processors line cards and fans of a dedicated olt shelf you can

12:02 see that there's going to be a savings that are going to be able to achieve in the central office or in the remote cabinet

12:09 this gives you also gives you the ability to reduce the size of the power plant required the backup power the

12:16 batteries required as well as the cooling equipment and or at least costly time-consuming

12:22 upgrades to those devices when you go to upgrade those one other thing to note is that with the

12:28 elimination of the olt shelf you no longer need the high speed up links to

12:33 the access router this frees up additional ports increases reliability

12:38 and reduces cost in both the optic cost as well as the power required to be able to do that

12:48 i want to talk a little bit about how this would work in a deployment model

12:56 if we look at the pawn architecture in the network we can see uh you know this is a typical

13:01 service deployment showing serving a wide range of customers both residential and commercial

13:07 you know olts are generally deployed in a head-headed or central office environment or in a remote cabinet or on

13:12 a pole this flexibility allows for the distance the customer to the olt to be minimized

13:19 one of pond's main advantage is using a single shared fiber design saving resources as a single olt port can serve

13:26 many customers pond standards can support up to 128 customers on a single port

13:33 but julie i think you're seeing something different in the model of how customers are deploying time today

13:39 yes that's correct so at one time pawn infrastructure and here

13:45 we're really talking about the underlying odn was very standardized

13:50 in the beginning of pon in the beginning of epon and gpon we were really looking

13:56 mostly at 1 by 64 splits sometimes 1 by 32 split

14:01 but today i'm seeing a much wider variety there's some overbuilders that have even done one by

14:08 thirty 132 um sorry 128

14:13 in an attempt to cover to really like a land grab get as much out there get as much fiber deployed as possible own that

14:20 fiber pipe like a land grab situation i've also

14:25 seen much lower split ratios one by sixteen one by eight

14:31 and some analysis has shown that even one by four can be much more

14:37 economical than a point-to-point active ethernet approach so there's a lot of

14:42 variety out there and that's part of why the flexibility flexible approaches have become

14:48 so important because different operators have very different strategies on what they're trying to achieve such as

14:54 coverage versus a much bigger pipe for example

15:01 well thank you julie and you know i've kind of seen the same thing in my talks with customers where maybe you know even

15:06 though the pawn standards say one one by 128 really you know focusing in on one by 32

15:12 or smaller or at least the ability to further break that down as you get customer demands like you say building

15:20 it out for the land grab model where you do uh you can deploy it with a one by twenty one twenty eight

15:26 and then be able to scale that down as you start adding customers as servers and that's where having this module ot

15:32 is nice because you're not stranding olt ports out there in advance you're adding them as the customer demand grows

15:39 so that really helps you out with that and then you know since the same device could be used for

15:44 multiple services it's easy to add the olt anywhere you know since uh 10 gig pond you know

15:51 amplifies the bandwidth fundamentals upon you know places where you've been able to use pawn

15:57 haven't used pawn before because of the lower bandwidth it really gives you the ability to use that and you brought up

16:04 the point about a one by four split you know that really becomes a great alternative to active ethernet

16:10 deployments and it's uh really also being able to see pond being used in applications that

16:16 are not residential in the commercial space as well and this is well we're seeing

16:22 um you know places like inside buildings where you know maybe riser fiber is a premium or

16:29 even within in campus environments it really kind of has those plays and it's also important to note that you

16:36 know the pond infrastructure that's out there in the in the physical plan we're talking about the splitters and uh the

16:43 combiners and uh all those gear this is the same infrastructure that's used for one gig pond is the same infrastructure

16:50 that's used for 10 gig pond and will be used before these passive devices are the same low

16:56 cost devices that we've been used today so nothing special has to change in the outside plant to make this

17:02 but as you're seeing as you were saying julie that reducing the the split counts is really some of the models that we're

17:08 seeing these providers go to you know um with the um

17:14 modular ot you can also you know you the explosion of iot private 5g

17:19 hospitality remote learning as anisha mentioned and high-speed wi-fi have all driven higher demands and locations

17:25 where pond has not traditionally been looked at as a feasible choice but with 10 gig pond it really becomes a

17:32 decision point that can be used for deploying your network

17:40 as you can see the applications for pond are far-reaching the innovation of the modular pond olt

17:46 allows for common ip service fabric to be deployed for all services

17:52 you know so i mean you can see here there's a whole lot of different types of services that can be offered with pond

18:00 so if i can if i can ask a question here um you know how can an operator manage

18:05 multiple applications on a single pond network and i think specifically how does

18:10 juniper's approach support this objective how does this fit into the

18:18 your existing management system for example

18:24 well sure well one other that's a great question you know one of the things by creating a common ip fabric

18:31 and this this ib fabric you know lives at the heart of um you know where

18:36 you know things that have been deployed in service provider networks and even in enterprise networks for a while

18:43 you can have a streamlight approach for all applications allowing for simplified engineering as

18:49 you reduce the complexities of separate networks multiple devices a myriad of routing protocols the

18:56 ability to move seamless between direct fiber active ethernet or pawn allowing for adaptations because now pawn is

19:04 treated just like another access in the network it's uh you know it's an interface in

19:09 the device so there's really no way a difference in how you would treat a direct directly connected mobile

19:16 backhaul service versus a pawn access side or versus a another site plugged

19:22 into the router because now everything is shown is brought up to the router level and you're able to apply the qos

19:30 the quality of service models apply sla parameters and be able to deliver these seamlessly and

19:37 effortlessly no matter how the the network evolves you know one of the key requirements in

19:43 offering pond services is subscriber management this cloud metro design allows for

19:48 centralized deployment of the broadband network gateway or bng device

19:53 with the flexibility of using technologies like evpn over mpls to connect to the

19:59 customer services this allows for simple management i p address application

20:05 if you need to add services like network address translation or nat and even the law enforcement uh

20:12 compliance services that you need to do if you're providing residential services

20:17 as you can see by having this simple cloud metro design you can create a scalable design as you can keep adding

20:24 nodes you can keep increasing speeds from you know 10 gig to 100 gig to now 400 gig

20:30 and be able to deploy a high high capacity platforms that have both pawn

20:35 and non-pond services if you look at the uh you know the crowd

20:42 cloud metro as a whole and what this means the net networks and how you know

20:47 by pulling pawn into this really gives it is an innovation it's the converged network for use all

20:53 use cases a cloud metro converges all metro use cases whether it be residential business

21:01 mobile backhaul transport onto a single converged architecture with a single operational

21:08 model network operators can also apply special treatment to different traffic and service types

21:14 under different service level agreements slas uh over the same infrastructure

21:20 by leveraging this a cloud metro networking intelligently steered traffic to the right physical or virtual

21:26 resource in the most efficient way to optimize the user experience

21:31 it optimizes capacity and utilization with control plane and user plane separation

21:37 or cups and modern traffic engineering protocols whether it's commercial traffic that

21:42 gets handed off directly to the internet subscriber traffic needing services from the bng

21:48 order deployment of local caching and services the cloud metro provides an intuitive and scalable framework

21:59 i think anisha was going to like to go through juniper's approach to howard handling pond networking

22:06 hey thanks robert so the unified pawn is supported by

22:11 juniper's multi-service a65400 series which also supports advanced metro use

22:18 cases so these are access aggregation platforms that combine one gig and 10k

22:24 client services with hundred gig uplinks including 100 and 200 gig

22:30 dwdm options for packet optical convergence flexibility

22:35 as robert mentioned the 10g pawn olt in our solution is treated as a standard

22:40 ethernet port within the acx this greatly simplifies the provisioning required for the solution

22:48 the standard junos features and functionalities are leveraged to provide both the control plane and data plane in

22:54 japan at jonathan what we have combined the acx router with the

23:01 smart pluggable revolutionary olt which comes in an ssd plus form factor so this

23:07 eliminates the old shelf helps tackle the power and space constraint and reduces the solution from

23:14 a toolbox solution to a one box solution the old supports selectability of for

23:20 both 10 gig sjx phone or 10g epom along with the management platform to

23:26 control and provision all functions on the pawn network leveraging the pluggable ssp plus form

23:32 factor we create scalable design that allows your receipts to provide multiple services like mobile.com

23:39 direct internet access along with on services thus eliminating the need of any

23:44 specialized services or separate network we have integrated the pawn controller into junos so the operators can take

23:52 advantage of juno's operating system juniper bngs paragon automation

23:57 and more as they add 10g spawn offerings to their service portfolios

24:02 it also interrupts with third-party pond distribution equipment thus avoiding uh all the vendor lock-in

24:09 issues we have a micro climate management system the ncms it is a single page web

24:16 application which provides graphical user interface for provisioning and managing the pawn network

24:23 with npms users can define templates for standard service deliveries easily

24:28 onboard the olts and onus create end-to-end services on the pawn networks manage the orts and onus in

24:36 network including firmware management and monitor the pawn network and collect details of network health and fma

24:43 compliance there is also a netcon server that provides direct provisioning over

24:49 standard space interface through the mcms gui a user can select

24:54 and when you add the endpoint and define a service based on a fully customized template

25:00 to summarize juniper's unified pond delivers a high density standard based pluggable

25:06 architecture combining an integrated and consolidated 10g pawn olt transceiver

25:12 and the pond management solution with the acs universal metro router

25:17 the combination of an open design allows the use of a large ecosystem of third-party onu vendors eliminating the

25:24 access of access vendor locking issues and the bng with advanced subscriber

25:31 management features gives the the pawn network access and the metro access aggregation routing

25:37 capability for a complete converged access solution so this is a complete converse active solution that you're

25:42 looking at so isn't it exciting julie what are your thoughts on this one

25:50 yeah so one clearly one of the goals is to try to converge the access network

25:57 you know we've seen it at the services level right where we've seen operators either integrated operators

26:06 or fixed-only operators who then become mvnos you know virtual mobile operators

26:12 offer voice services data services video

26:17 services and by voice you know whether you're at home or or on the mobile

26:22 network what's taken much longer in my opinion is the convergence of the access network layer and this is becoming more

26:30 and more critical given the growth in traffic and the need for operators

26:36 to control their costs both capex and opex

26:41 and this is clearly one of the advantages of of the pond technology is the ability to to bring down the cost

26:48 by reusing that network you know the cost of the pond network is really in building out that infrastructure the

26:54 construction project whether it's buried fiber cabling or overhead so why not

27:00 reuse that network for as much as much as possible um you know and then oops sorry and this

27:06 leads to the conclusion slide that i have which is that pan and here we're talking

27:12 specifically about tdm pond which is what has been so incredibly successful

27:17 in terms of acceptance adoption deployments upgrades you know it really

27:23 has evolved enabling capex and optic savings and providing flexibility to different

27:29 kinds of broadband service providers you know higher and higher bandwidth we've

27:34 seen the movement from you know ippon to tenji ippon from gpon to xgs

27:40 jupon more and more around 25g there have been announcements

27:45 this year about 25g live networks and a lot of testing going

27:50 on and certainly in the future we expect to see 50g we've even heard about 100g

27:57 lab testing it's gone upon itself has really gone beyond best efforts supporting

28:03 non-residential subscribers and applications and becomes a unifying access technology

28:09 and being able to bring access into the metro and taking advantage of a lot of the metro capabilities

28:16 that the metro network providers vendors have given to their to their customers

28:21 the service providers so it's really a lot of development that we've seen over the last years and that we're going to

28:28 continue to see you know given the very successful role that pond has plenty upon technology has

28:34 played and now i want to move to q a we've gotten in

28:40 really a lot of questions please keep submitting them as mentioned if we don't get to all of

28:46 them now we will certainly we keep them and juniper will be happy to answer the ones

28:53 that that we don't get to live so one of the questions that that's come

28:59 in a good bit is juniper has focused on the olt side so

29:05 how do you ensure that there will be enough ont onu vendors

29:11 for your customers to use with your olt solution

29:20 okay yeah um and that's a great question julie and that's a one of the things

29:26 that's been a differentiator is our approach to looking at pond in an

29:31 open environment and that really kind of leads to how junipers approach routing in general and

29:36 most of our products is open standards and creating the market for it we've already seen

29:43 several vendors in the market that are producing the ont onu devices out there

29:48 ranging from traditional uh simple onus to full function gateways that

29:55 support features all the way up to like wi-fi six and you know by following the standards

30:01 that these are easily onboarded onto our system and we've we've got a pretty large array

30:07 of uh ones that we've already interoperated with ones that we're in field tests with and ones that we have um you know that

30:14 we're working with customers to deploy we are seeing quite a bit more uh uptick

30:20 and demand as far as on the rfp side of xgs pawn deployments we're seeing this

30:26 as being coming the predominant standard and this is what we're seeing a lot of the onu vendors support even though they

30:33 have the capability of doing epon we're seeing xgs pawn being the the

30:38 leader right now at this time for 10 gig pond deployments and so it's uh you know that that

30:45 coupled with uh you know the open system and the onboarding side with the vendors it really

30:52 we're not concerned with you know not having the far end devices on there in the best breed of approach

31:00 yeah thank you so as an analyst in this market segment let me add

31:06 a little bit here about pawn and what what i'm seeing so in the second quarter of this year

31:14 we already saw in north america xgs pawn

31:19 shipments almost match those of g pawn so there's been very rapid adoption of

31:25 xgs pawn olts and here i'm talking on the olt side we expect the onts to are

31:31 happening next gen o and t is specifically xgso and ts but certainly

31:36 on the network side we've already seen the movement a very strong adoption of xgs pawn it's

31:42 simply there's a couple of reasons why one is that it's stable

31:48 there's numerous vendors supporting it it's commercialized and there's been

31:54 a lot of lab trials done a lot of live networks

31:59 deployments done so there's a lot of confidence that xgs is mature

32:05 second the prices are coming down and so if an operator who's trying to decide between gpon

32:11 and xgs pawn for five times the downstream

32:16 and eight times the upstream because we have to remember that g pawn is 2.5 over 1.25 so for tremendous bandwidth

32:25 growth or capabilities you're not paying um eight times for xgs pawn equipment

32:33 so the many operators that have not yet begun to deploy pond networks and we're

32:38 definitely seeing this with the overbuilders and with some of the even incumbents who

32:44 have been slower to build out the pond networks some of them are beginning with only xgs pawn

32:51 if they're if they're telcos a few cable operators are doing the same with 10g epon

32:57 but certainly for those that are looking at g-pan we've seen a lot go with with xgs and

33:04 with the momentum of xgs pawn shipments on for the network side you know whether

33:11 it's a central office or a head end if it's a cable or in a distributed environment

33:17 um so smaller let's say olt solutions to be distributed out into the to the field

33:24 the momentum is there the price points have come down significantly and consequently we're seeing we're

33:31 seeing rapid adoption outside of china it's almost only xgs pawn

33:37 and that's because the operators really want to see the symmetrical capabilities to support

33:44 a lot of enterprise services and exhaust transport

33:49 so another question that has a question that's come in from several different

33:55 people is if you can talk a little bit more juniper about the unified ip fabric

34:01 you know what does this approach really enable me to do in terms of convergence you know you talked about it a little

34:07 bit during your presentation but if you can go into more detail i think it would you know answer

34:14 probably 10 of the questions that we've gotten in around that

34:21 that's great i don't know anisha would you like to uh

34:26 um you can go ahead with that one drop it not a problem no i um yeah and you're

34:32 right there were several questions on that and and it is great about that is you know one of the things that when you

34:38 look at the way you know traditional networks have been built out maybe with some sort of

34:43 ethernet ring protection or layer 2 type of side or wdm the ability of having an ip fabric and

34:51 taking advantage of what we're seeing with 400 gig gig links now and the capability of the

34:57 platforms and then the simplification of protocols things like segment routing uh you know

35:05 mpls over segment running being able to use for traffic engineering to be able not to have to have reserve bandwidth

35:11 and being able to create this ip fabric gives you a model that you can you know

35:17 almost like the shampoo bottle and lather rinse and repeat you can actually create the same model to

35:23 for deploying services across your entire network you know the edge device now can

35:29 actually pick up the what if you're deploying enterprise services and or if you're deploying you know

35:35 mobile back call or if you're doing other types of services at the edge the ip the common ip fabric

35:41 makes it easy for you as an operator for training for management for deployment

35:47 to be able to have one common protocol one common set on there and unless this is really what lends it

35:53 into having pond go into places where pond hasn't gone before with residential side

35:58 whether it's using for iot devices where you're using pond to aggregate up from outside locations

36:05 whether it's in in different buildings or whether it's you know for hospitality

36:10 applications we're seeing quite a bit in the campus market looking at for uh in

36:16 for dorm room or even remote building uh sides it's a uh there's quite a bit

36:22 things that by having this you know your configuration of the device at the edge you don't have to put a special device

36:29 for business services you're not putting a specialized device for residential services you're having a common

36:34 transport side and you're elevating your transport to this ip service fabric

36:42 so what if i can just add on a question for you robert um

36:48 about there being a traffic jam and at the metro level

36:54 yeah and there is i mean if you look at where the growth is uh you know the you know i i one of the things i like to you

37:01 know show the chart is of um you know the metro is where the pressure's at the metro is seeing the yeah as you start

37:08 upgrading for the links you're the metro is the first place to feel the pressure

37:14 it's uh you know that's and by using uh an ip fabric versus using traditional

37:20 layer two transports you're eliminating links that are blocked for you know for

37:25 ring for loop protection and being able to fully use the bandwidth

37:30 also by enabling uh protocols like segment routing you can now take advantage of traffic engineering you can

37:37 actually have your low latency high bandwidth services take the most expressed path through the fabric and

37:44 being able to spread the best effort traffic along other links in the network

37:49 this will allow you to take full advantage of your network before you do costly upgrades of adding links or

37:54 pulling new fiber great thanks

38:00 another question is around coexistence so what do you say to an operator

38:06 who's already deployed you know either one gig epon or 2.5 gig

38:12 g-pawn how how can they work with um juniper solution here

38:21 and that's a great question julia i mean we get that quite a bit because you know the solution that we have is 10

38:27 gig symmetrical pond with whether it be 10 gig epon or xgs pawn

38:33 so uh one of the the nice things that they've done in the standards bodies is that

38:39 these uh services use different wavelengths on the optical spectrum

38:45 so by using what's called a coexistence device that can be combined these

38:50 traditional one one gig two and a half gig pond with 10 gig pond you can

38:55 actually run these services over the same fiber now uh what we've seen is that uh you

39:02 know with the deployment of our solution is that most people are looking to cap

39:08 their current one gig uh two and a half gig pond investments or their separate olt shelves so by using these external

39:16 uh coexistence devices it allows you to seamlessly you know add these services

39:21 on there on the same fiber tree and as well as being able once you migrated customers to 10 gig services to

39:28 roll them over and remove the coexistence device from the network

39:36 so their upgrade

39:41 problem today um efficiently and and then give them room

39:48 it sounds like there's an efficient way that you can help them here if i'm understanding this correctly

39:54 yes yes and by doing this it allows you know to be able to pick and choose where

40:00 you do your upgrades you know lots of times view it's easy to say we're going to deploy new markets with the existing

40:05 technology but maybe you do have a you know a customer along the network

40:11 maybe maybe a business customer or some of your higher end customers that you want to provide a higher speed service

40:18 to by using this you can you can layer on top of the existing pawn network and

40:23 be able to upgrade select customers on there and leave the ones that you have on there and maintain the investments

40:29 you have in your your legacy gpon network

40:34 yeah that's that's really important right so you met you both of you touched on a

40:42 topic that i think is extremely important that once you move outside of residential

40:48 you get into a lot of questions around reliability security slas

40:55 you know typically as residential users most residential users don't

41:00 don't have slas and would not be willing to pay for any type of sla in a service level agreement or

41:08 you know promise of a fix within a certain amount of time or a payment if that doesn't happen so i'm interested

41:16 for you to go into a little bit more detail on how you can insure

41:22 slas because this is one of the key from our findings from surveys with service providers and

41:28 you know yes they may be considering the use of pawn beyond residential but then they raise a lot of a lot of questions

41:35 and one of them is around well can you still give me an sla how are you going to monitor that sla

41:41 what's that lsla going to be based

41:47 i don't on nisha if you want to touch on active insurance yeah yeah definitely so uh

41:54 essentially we have the mtms system right and uh that it will help us

42:00 monitor the old we know and use and check get all the network health and ensure that

42:06 the sla compliance is in place along with that with the fact that the phone controller is integrated on two nodes uh

42:13 we have an entire bigger paragon automation suite that takes care of the

42:18 sla parts right so we definitely have product lines in place uh that are taking care of this

42:26 sla demand right like ask um

42:31 if it's all dead like if you look at it from the solution end to end point of view right uh which i don't know robert

42:37 if you have more details um that you'd like to share um sure sure i mean and julia i know you

42:43 mentioned that you know customers residential customers aren't paying don't want to pay for an sla type of service but it's also

42:51 important to note that with a lot of the the recent funding rounds for projects like rural broadband and

42:58 being able to increase residential services there are requirements from the fcc and other agencies that you maintain

43:06 a certain performance and latency so it is important to monitor those and as nisha mentioned that the the

43:13 ability to do this is in the mat in the ability to gather statistics and being able to rather historic

43:20 statistics and being able to produce those in reports so it's uh it's key and now she touched

43:26 on the fact that our uh the microclimate management system is gathering these

43:31 stats and there's lots of stats that you can gather from both the olt and the onus to be able to ensure that you

43:38 actually are delivering the customer experience that they're paying for

43:43 [Music] great thank you so there's um

43:49 an interesting question here our current pond provider is challenged

43:54 interoperating with mpls services as a leader in mpls does the juniper

44:00 solution allow us to easily deploy mpls over the integrated pond network

44:07 sure and you know i'll jump onto this is you know we've cut out the uh the middle man directly by having the pawn services

44:14 on the device you know what's kind of nice about that and what's also nice about juniper as

44:20 far as a leader in broadband network gateway services is that we're able to put uh mp bring

44:25 the mpls direct network all the way up to the pond network and being able to tunnel subscribers

44:31 through layer two circuits or evpn across the mpls network to terminate directly on the bng

44:38 and one of the key features on our bng platform is the dynamic service creation

44:43 so this means you're not manually provide provisioning subscribers on the bng you have the bng in a listen mode

44:50 where it's listening for subscribers as they come online and dynamically uh building the service

44:57 authenticating the service and provisioning the service as they come on there so you know

45:03 the neat thing about it to reiterate by having the pawn olt as part of the router and part of the

45:09 cloud metro architecture it is become it's directly integrated with the mpls network and you get all

45:17 the benefits of all the traffic engineering and everything that you do for your other services over mpls

45:25 great thank you so just to add on to that one right uh so uh the fact that

45:33 uh the pawn controller is integrated on two nodes uh junos has a bunch of services that can be utilized right so

45:40 this entire transition or the the packet transfer uh is gonna be pretty seamless right uh it's not going to cause like a

45:47 lot of problems with respect to an overlay function so it's very easy we can definitely do it the short answer is

45:53 yes

45:58 that great great to hear that um so another question is how does the

46:04 juniper or can the juniper solution support a distributed architecture for

46:09 remote locations like deploying pond in the new business park

46:15 interested in you know this question came in in a couple of different forms but the point is about distributed

46:22 architecture sure i mean i think you know by nature

46:29 with the modular olt that is a distributed architecture

46:34 we we are now putting the olt all the intelligence of it on on a single sfp

46:41 plus so instead of a single olt shelf you're distributing the olt functions across

46:47 the individual plug so you're decreasing the blast radius of the failure of a single

46:54 device but what this also means is now this olt can live outside of the

46:59 traditional network locations this could live in the basement of a building this could live in a wiring closet at the end

47:07 of a you know in a strip mall so this allows you to push these services further out and all your olt

47:14 ports don't need to be in a single location and that's what the flexibility of this modular design brings to you and

47:22 by able to connect them all together with the ip service fabric and being able to deploy those in devices that are

47:28 either you know in conditioned spaces or out in hardened locations this this gives you the flexibility to

47:34 provide those services and get into those markets you

47:42 yes definitely nothing more black on the back one

47:47 great thanks so there's uh there's a couple of questions here that i would like to to take um and it's around the

47:56 next generations of pond and and what do i see happening so one of them is what's my take on ng

48:02 pontoon so ng pontoo has only been deployed by

48:08 a few a very few operators and what it comes down to is the cost of

48:13 tunable lasers they're just expensive so from a an architectural viewpoint ng

48:22 pontu reminds me a lot of wdm pond which is that it's it's great on paper and it looks

48:30 like it has many advantages on paper the problem is the cost

48:35 and because ng-ponto has not been widely deployed it does not have any volume

48:41 behind it which means that the cost there's just not enough pressure to bring down the cost

48:47 of those tunable optics so i don't expect to see it widely deployed i don't expect to see it

48:54 gaining significant momentum um

48:59 and you'll you can see that in the omnia on the equipment forecast that yes there will be some deployed

49:06 year you know every single year but it's just not not in volume compared to

49:11 xgs pawn so what about 25 g pawn versus 50g pawn and i hate the use

49:17 of the word versus here because to me it's both so we've begun to see some 25g pawn

49:25 it's not standardized by the itu-t it has been standardized by the ieee

49:33 msa was formed around 25 g pawn and as i mentioned earlier we began to see some

49:38 deployments this year and we expect more it's not for in my opinion we will

49:46 25 gpan fills a need and and the need it comes from two places it comes from

49:53 service providers who want to be able to offer 10 gig

50:00 services even up to 15 gig services to enterprises

50:06 so there are a number of broadband service providers who have gone aggressively

50:12 to enterprises and to bring those enterprises onto the pond network

50:17 with high bandwidth services not every enterprise of course needs 10 gig or 15 gig or beyond

50:24 but with 25 gig selectively used they can offer they can offer those higher

50:30 bandwidth services the second place where we've seen interest in 25 gig

50:36 is around different types of x what i call excel transport

50:41 such as wireless backhaul and again it depends on the topology

50:47 of the 5g small cell network or what the operator expects that topology to look

50:52 like and whether they need 25 gig or not

50:57 then there's other operators who say we don't need 25 gig we're going to wait

51:03 until 50 gig becomes available

51:08 and in many of those cases those operators do not have plans to use pond for transport

51:16 and so sort of coming up a few layers in my analysis here han has been so successful

51:23 as an access technology that we're now seeing some diversity and in my opinion the

51:30 pond ecosystem can handle it and what do i mean by diversity really diversity

51:36 in applications and types of subscribers if we go back to one of my early slides

51:42 pond was the best effort ftth and fiber to the building technology 15

51:49 years ago as it's been widely accepted and very widely deployed

51:54 operators are now using it for different strategies depending upon how much fiber they have in their access

52:01 network how much competition they're facing from other operators or from

52:06 overbuilders wholesalers for example and what types of subscribers they want

52:11 to go after or have so there's a lot of different

52:17 strategies now forming around the access network and how best to

52:24 make more money on that optical disrupt distribution network so we're seeing more diversity and the

52:30 good news is that the ecosystem is at the point where it can it can handle it well

52:36 um so this is a a question another question

52:41 around slas so regarding pun sla monitoring and end-to-end service kpi monitoring would

52:49 you recommend use of wide y.1731 in general and specifically for a

52:55 network of around 300 000 subscribers so i know that this is a very specific question i don't know robert or anisha

53:02 if you if um if you want to take that one

53:10 sure

53:15 you can add on after me i think my question uh my aunt is just gonna be like it's really different right um

53:23 300k subscribers yes but then what are the other things that you're trying to do how is the deployment going to look

53:29 at so uh not a really straightforward answer but it just depends i don't know but you

53:34 have more well yeah so i mean i guess there's a couple of things that you want to look at um as far as your subscriber

53:40 services i mean obviously the the health of your your network going to the olt or

53:45 going to the access device uh is key and we are seeing a move from

53:50 using things like bfd or other protocols to using the 1731 type of monitoring

53:56 device to get better oam data out of the links in your network

54:02 that that's that's one place for that to be used uh as far as monitoring your subscriber

54:08 health like we mentioned there's a lot of statistics you have and there's also the rate of how much statistics you

54:14 gather and how much you can produce with that one of the things that we've looked at is it's really coming into the key of

54:20 what's looking at with current network deployments and where people are moving their network deployments to and it's in

54:27 automation and looking at how you can gather this data and how can you have processes

54:32 looking at this to develop you know not only is this you know getting some sort of alarm or getting

54:38 some sort of data going is this something i need to be worried about and that's one of the texts that we've

54:43 been taking with some of our applications in our paragon automation suite is to develop what is a baseline

54:50 so that you do know what is an anomaly but what is just regular standard values

54:55 and that's that's key because what may be happening in one part of the network is different than what happens

55:01 in the other so again i think going back to your question about uh using why 1731 i think

55:08 it's that's important to incorporate into your network to look at your link health look at your connections on that

55:14 side and being able to gather additional data that you would probably not traditionally have with other oam

55:20 protocols great thank you so one one quick

55:26 question which i'll take which came in after my discussion of the next generations upon is you know can these

55:33 coexist and yes they can coexist this is something that the pond ecosystem

55:39 made sure of is that there is coexistence so you do not have to

55:44 rip out anything that you've put in and you can decide where and when to upgrade both on the

55:51 network side and on the subscriber side and this is really important because what this means is that you can do

55:57 network side of upgrades before upgrading a subscriber and then only

56:08 could be upgraded or is willing to pay for a higher level a higher speed service

56:14 so we're almost um out of time so i think julia i would like to interject something right there

56:19 sure um one thing to notice you're mentioning on that is also is the platforms that are

56:25 being developed at this time uh those sfp ports are a lot of them now

56:31 are capable of both sfp 10 gig 25 gig and 50 gig so with this monitor device

56:37 it's going to mean that these will be able to live side by side in the same device as well so just wanted to add

56:43 that note there yeah thank you yeah that that's that that that's important thank you um great so

56:50 um i'd like to thank everyone for joining us today and and for submitting your questions and comments i

56:57 know we did not get to all of the questions but as i said we do have these and we'll be able to follow up
