Juniper Networks: Emerging Use Cases for IP over DWDM

0:01 [Music]

0:06 I'm Sterling perin with heavy reading

0:08 and I'm here with Moran Roth from

0:10 juniper and we're talking about the

0:12 future of Ip over dwdm good to see you

0:15 again nice seeing you Sterling it's been

0:17 a few months ofc and back at uh eock 24

0:21 so another hop in show a lot going on

0:24 with juniper um yeah so IP over dwdm um

0:29 spending a lot of time this Year from a

0:30 research perspective on the topic

0:32 working with of course you guys in the o

0:34 on a project right now but um from your

0:37 perspective what what kind of traction

0:38 are you seeing around ZR and ZR plus and

0:41 and IP over dwm right now so it it

0:45 started three years ago in Earnest with

0:48 a

0:49 hyperscaler h deploying 400 gig routers

0:53 in volume and started to use 400 gig ZR

0:58 mainly for data center interconnect use

1:00 cases about two years ago this expanded

1:03 beyond the hyperscalers to Cloud

1:06 companies again adopting the 400 gig

1:10 platforms with a 400 gig ZR and just

1:14 last year after the zbm Optics uh

1:18 started to appear in the market we

1:21 started seeing a lot of traction with

1:24 service providers and

1:26 Enterprises using it h for uh more than

1:32 just data center interconnect started

1:35 using it in the Metro H and even

1:37 Regional

1:39 networks so this the Zer dbm is of

1:41 course the high output power which from

1:44 a Telco perspective helps you get

1:47 through rhm networks and and greater

1:49 reach um so you're you're starting to

1:52 see driven by that

1:54 particular um variant of of ZR that is

1:58 really what you're seeing as as a

2:00 launching pad for more you know a Telco

2:01 market and Enterprise as well exactly so

2:05 we see it for even for Enterprise for

2:07 example research and education networks

2:09 are building um you can think about

2:13 interconnecting many uh

2:16 universities across States and uh or

2:19 across Europe uh and this requires the

2:24 zbm because you are going over a radm

2:26 based line system so this is an example

2:29 for Enterprise

2:30 service providers as we know they are uh

2:34 they have much larger networks it's not

2:37 just point to point um so they started

2:40 relatively slow uh but we see a

2:43 significant acceleration acceleration of

2:45 their adoption this year with a lot of

2:48 field trials and initial deployments and

2:52 you would put them in the bucket of I

2:56 guess ZR Plus or maybe ZR plus with zero

2:59 DBS M or do you I mean when you say zr+

3:01 is it pretty much zero dbm is that kind

3:04 of yeah so H

3:07 zr+ minus 10 dbm was in a I would call

3:11 it in a bind yeah because by the time

3:14 service providers started deploying it

3:17 or using using it zbm became available

3:21 and then it's a super set that can they

3:23 can use for every use case including

3:26 rodom networks yeah and this is where

3:28 really where we see now zero dbm takeoff

3:31 y kous are you seeing um you know you

3:34 could you could also call zero dbm a

3:37 super set of of even ZR are you starting

3:40 to see in in maybe Telco and Enterprise

3:43 just saying we're just going to go with

3:44 with ZR plus and forget about you know

3:46 the the ZR variant or do do you see ZR

3:49 having a place in in Telco and

3:51 Enterprise as well so we see both we see

3:53 even the same customers

3:56 using uh ZR for data center IND connect

4:00 or router interconnect across a few tens

4:03 of kilometers between colos and then

4:06 using zero dbm for Road and based

4:09 networks on the other hand we see the

4:11 other uh side of cloud companies using Z

4:17 dbm because they they prefer a single uh

4:22 transceiver that can have any use case

4:25 on their Network so they they use a zero

4:28 dbm to do this C for uh 40 km and even

4:33 100

4:34 kilm um and and again they prefer the

4:37 Zer dbm so they're all in play yeah

4:38 change gears a little bit um so it was

4:40 interesting following the the evolution

4:43 of of 400 ZR ZR plus it's gone both up

4:47 market and you know what I call down

4:49 Market 800 gig and then to 100 so maybe

4:52 kind of talk through both of those maybe

4:53 start with 800 ZR ZR plus what is

4:56 Juniper seeing and and what are you

4:58 expecting so we started uh demonstrating

5:02 our 800 gig solution including the PTX

5:06 1000002 and the 800 gig zrzr plus

5:09 transceiver at ofc right we talked about

5:12 it at ofc yes we have the demo here at

5:15 EO as well um and we see a lot of

5:19 interest both from cloud companies and

5:23 uh service providers to start doing

5:26 field

5:27 demonstrations the big benefit that 800

5:30 gig brings with its H increased

5:33 performance is longer distances so you

5:36 can take the IP over dwdm Technologies

5:39 from DCI and Metro even to Long Haul and

5:44 this is what 8 gig ZR plus can do with

5:47 its H better flexibility running at at

5:50 running at less than 800 gig though

5:52 you're saying in that case so it's

5:53 running at a 600 gig mode or or 400 gig

5:57 mode but even uh uh now you start seeing

6:02 uh probabilistic constellation shaping

6:04 modes coming on board that can even

6:07 stretch the 800 gig further than 400 gig

6:11 ZR plus can do today what one thing uh

6:14 and then I I'll I'll go to a 100 Gig but

6:16 you know you're you're a router supplier

6:18 and um from the router perspective you

6:21 know say you have you know different

6:23 different routers is it really just a

6:24 matter of taking an 800 gig plug when

6:26 you know so and so comes out with the

6:28 plug and and you plug it in or is there

6:30 a big overhaul required from the the

6:32 router perspective you know the router

6:33 hardware and software yeah so there is a

6:36 lot of uh qualification uh to make sure

6:40 that you have compatibility between the

6:42 transceiver and the host the router in

6:45 this case h it starts from uh everything

6:50 Hardware related right mechanical

6:53 electrical signal Integrity power

6:56 consumption is a big uh factor and um

7:00 and and then thermal and what we found

7:03 out that there is a lot of variations

7:05 between different suppliers in terms of

7:07 the thermal map you can say okay I

7:10 consume X Watts but the question is how

7:14 this x watts are distributed and how the

7:18 air flows uh works in the in the router

7:22 so we found that especially this thermal

7:25 compatibility is something that requires

7:27 a lot of uh effort to to make it work

7:32 right yeah as I expected um 100 ZR you

7:36 know this was uh kind of the Forgotten

7:38 data rate at least from coherent and uh

7:41 seems to have a lot of Promise um but

7:43 kind of taken off maybe a little slower

7:45 than than I would have expected but what

7:46 is junip for seeing on the 100 ZR front

7:49 yeah so we have customers today using

7:51 our 4 gig ZR Plus at a 100 Gig mode in

7:56 some cases you know if you have really

7:59 bad

8:00 fiber and you can use that and it can go

8:04 a very long distances H for dark fiber

8:07 it can uh

8:09 do 100 120

8:11 kilomet H but really the promise is

8:16 getting this 100 Gig ZR into qsfp 28

8:20 right and into a the power envelope of

8:24 qsfp28 which is maximum of five Watts

8:28 low very low that's the we see the

8:30 benefit H we as I mentioned uh for the 9

8:34 gig for 100 gigs zard as well we started

8:37 doing demonstration at ofc

8:40 2024 with our H access and aggregation

8:44 routers and uh 100 Gig

8:47 ZR uh and um we see a lot of interest

8:52 from especially from service providers

8:54 and Enterprises absolutely less from the

8:57 cloud Community I agree completely right

9:00 uh the other one you know talking about

9:01 hotel Co and as I've delved further and

9:03 further into this project with you guys

9:05 in the oif the the management uh

9:08 somewhat surprisingly but maybe not has

9:09 become the a real big um you know area

9:14 of involvement or concern um kind of and

9:17 it sort of breaks out into two two parts

9:19 there's the node management the plug to

9:21 host and then the network management

9:22 maybe talk through both of those as um

9:25 as a router vendor that's you know

9:26 having the plugs uh embedded um no

9:29 management and the seus work is that

9:32 kind of has that covered what's needed

9:35 from a node perspective yeah so H I'm

9:38 looking at it as um you know uh three

9:41 floor building sis is the ground floor

9:45 where simis enables management of the

9:50 transceiver by the host and really simp

9:54 H standardizing or simplifying the

9:56 software so the same software can manage

9:59 any transceiver not just coherent any

10:02 type of of transceiver right Pam 4

10:05 cables um so simis was really

10:09 instrumental in making that

10:12 simplification but this simis is only

10:14 the ground floow the second floor is

10:18 where the software of the host is

10:22 enabling uh the open config and

10:25 Telemetry to expose the coherent

10:28 parameters

10:30 uh to the management system and this is

10:34 where the host uh software uh it's the

10:39 whole software work and then the third

10:42 floor is really the controllers okay

10:45 right and for IP over dwdm you want to

10:48 see H end to end management between the

10:51 IP controller that manages the router

10:54 with the transceiver in it and the uh

10:58 Optical controller or nms that manages

11:01 the rodent based line

11:04 system and you want to see this

11:06 orchestrate orchestrated and this is

11:09 where tip uh has this uh

11:12 architecture that Define this

11:15 interoperability or interworking between

11:18 the controllers and then uh maybe I know

11:21 we're short on time but automation we

11:23 just did a webinar together very

11:25 recently automation has a a pretty

11:27 important role to play here

11:29 um at at I guess one or more of those

11:32 layers you just discussed maybe kind of

11:34 just talk quickly about where Juniper

11:35 sees the important role of automation

11:38 yeah so automation is critical for uh

11:41 reducing cost and for Expediting time to

11:45 revenue H just one example um we have

11:50 embedded uh active Assurance uh probes

11:54 in our Hardware our routers and this

11:58 enables a faster turn up of services and

12:04 uh 247 monitoring of the SLA so the

12:09 service provider can find issues before

12:13 the customer even knows that there is

12:16 something wrong

12:18 so and and then AI again everybody's

12:22 talking about Ai and machine learning

12:24 this is just the next step in automation

12:29 y right where the uh AI we see a bring a

12:33 lot of value for day two operations

12:36 where it can uh automate

12:40 anomaly uh

12:42 detection um help with root cause

12:46 analysis and uh suggest mitigation steps

12:51 and how to remediate the issue um and we

12:55 are integrating that we are now focused

12:58 on integrating that functionality into

13:00 our systems and a paragon controller

13:06 yeah so there there is a lot I mean it

13:07 starts with the plug bles but then as

13:10 you've described it it really builds and

13:12 builds and there's a lot of pieces that

13:14 that need to come together in order to

13:16 to roll out these very promising

13:18 architectures uh in in the future and

13:20 hopefully the the near future um but

13:23 yeah always a pleasure catching up with

13:24 you uh enjoy the rest of the conference

13:26 okay thank you Sterling thanks for
