0:07 there is no doubt sustainability has now

0:09 become a key topic to most companies out

0:11 there and within the telecoms industry

0:14 the need to innovate reduce energy

0:16 consumption and related costs appears to

0:18 be among the top priorities for

0:20 ecosystem players sustainability is also

0:23 at the heart of juniper Network's

0:25 solution called Cloud Metro which the

0:27 company introduced last year

0:29 to learn more about it I'm now delighted

0:32 to speak with Irene Zhang director of

0:34 product marketing Cloud Metro and

0:37 security at Jennifer networks hi Irene

0:39 thanks for joining us today thanks for

0:42 having me

0:43 so you talk about Cloud Metro is a new

0:45 approach to re-architecting traditional

0:47 Metro networks what exactly is new about

0:50 the cloud Metro

0:52 sure so when we think about Metro

0:54 Network it's essentially the um the

0:57 network domain where it's called SSN

0:59 aggregation right and so historically

1:03 that part of the network uh whether you

1:05 call it traditional Metro or retro Metro

1:08 is uh the function is very simple it

1:12 used to aggregate the traffic from the

1:14 SS Network and then pass it to provider

1:17 Edge and the core to

1:19 um and essentially it's just aggregated

1:22 traffic and passing it through there's

1:24 nothing super complicated now with Cloud

1:27 Metro fundamentally it is about applying

1:30 Cloud principles to re-architecting

1:33 building and operating the Metro Network

1:36 so what is new is that first the cloud

1:39 principle for re-architecting so instead

1:42 of

1:43 um a Scala approach we use the the cloud

1:46 spine and leaf principles to to have it

1:50 not only scale up but also scale out

1:52 with the IP Services fabric architecture

1:55 design and for building the system that

1:58 build a climate Network that those

2:01 systems have sustainability built from

2:05 day one and it's it allows you to

2:08 support slicing it allows you to be

2:12 energy efficient space efficient and

2:15 last but not least on operations

2:17 traditional Metro are very much menu

2:20 intensive manual operations and with

2:24 Cloud Metro the operations are primarily

2:27 Cloud delivered operations having the

2:30 automation delivered from the cloud as

2:33 SAS service

2:35 and why sustainability in Metro networks

2:37 important and why should it be on top of

2:40 mind for operators absolutely so for

2:43 operators that

2:45 um the industry standard body have

2:47 already started having different

2:49 standards to require operators to commit

2:52 to reducing their combat emissions itu

2:56 have it required to reduce 45 percent by

2:59 2030. gsma have most operators commit to

3:04 Net Zero by 2050. if we think about it

3:07 that's a lot and the the truth is

3:11 majority of the carbon emission for

3:14 telcos are from the scope 2 is scope 3

3:16 and then when we look at the different

3:18 parts of the network the Metro network

3:21 is where most of the Innovations are

3:24 coming for the next decade the Metro

3:27 Network we talk about this is where is

3:29 is essentially is not coincidence where

3:32 it's the metropolitan area network that

3:34 is close to population and so this is

3:37 where the edge Cloud hosting the

3:40 connectivity and service experience

3:42 converge and what I mean by that the the

3:45 places that people are moving their

3:48 workload to Edge Computing and while

3:49 there's a spectrum of location that you

3:52 can host the edge compute the for

3:56 operators the best location will be

3:58 within Metro where they have those

4:00 Central offices pre-aggregation site

4:02 because it's close to population so it's

4:05 still having the benefit of low latency

4:07 and at the same time it's large enough

4:10 so you can do resource polling and have

4:12 the business case so now as the traffic

4:14 are going a lot of them going to the

4:17 metro and from some podcast forecast we

4:20 know that it's gonna get from uh 2021 to

4:24 2027 over 500 increase since

4:28 sustainability the greenhouse emission

4:31 is directly related to the amount of

4:33 traffic travels to the network for

4:35 operators that want to really improve

4:38 their sustainability the Metro network

4:40 will be a key place that they have to

4:43 improve

4:44 that's a great Point you're making there

4:46 so how does cloud Metro achieve better

4:49 sustainability when compared to a retro

4:51 Metro Network so when we think about

4:54 improving sustainability we can think

4:56 about it for a couple aspects there is

5:00 the power or Energy Efficiency there's a

5:03 space efficiency and also the longevity

5:07 to reduce E-Waste so let's look at one

5:10 by one so first on the Energy Efficiency

5:13 as I mentioned for Car Metro systems

5:16 they are when we build a systems we

5:19 already have the sustainability the

5:22 built-in and so a couple specific

5:25 features one is um they have the the

5:30 Adaptive power Innovation where think

5:32 about it like a smart home where you

5:34 install Smart thermostat right what does

5:36 that help you it helps you turn off the

5:39 fixtures and other appliances at home

5:42 when you're not using it and that way it

5:45 allows you to intelligently save power

5:47 right and we apply similar logic that in

5:51 our Cloud Metro systems where when

5:54 you're not using certain functions when

5:56 you're not using certain packet

5:58 forwarding engines there are specific

6:00 software written in the system that

6:02 allow you to automatically turn them off

6:05 and that allows you to save power

6:07 and another thing is the um we decoupled

6:11 the power power shelf in the chassis so

6:14 historically when you use some big

6:16 chassis the power shelf is attached to

6:19 the chassis which when you need more

6:22 power then you might need to replace the

6:24 entire chassis and also the power supply

6:26 so when thinking about power let's say

6:31 you connect to a power grid there's

6:33 always a conversion loss when you how

6:36 much power you draw from the grid is not

6:38 a hundred percent to the power that you

6:41 can use for the system there's always

6:42 some some loss and the efficiencies how

6:45 you can minimize the loss is that you

6:48 can get over 90 of the power or is it

6:52 92.95 and we are super proud that our

6:55 car Metro are able to get certified to

6:57 Titanium which is the highest grade that

7:00 the the minimum loss that you you will

7:03 get from the um the power conversion so

7:07 all of this allow allow us to save

7:10 customers at least over 50 actually over

7:14 50 to 70 percent power saving so that's

7:18 the first part on a power efficiency on

7:21 a space efficiency that is where let's

7:23 say you you use the routers and you need

7:26 to deliver certain traffic and those are

7:29 physical equipment that sit on certain

7:31 space and what if you can deliver a

7:36 same amount of traffic or even higher

7:38 but with smaller footprint

7:40 that is where what we do that we look at

7:43 it we look at the system design and we

7:45 consolidate layers and consolidate

7:47 components and use the latest generation

7:50 chipset and in fact even have the fabric

7:54 to allow for future chipset so that you

7:57 will you will use the same like much

8:00 smaller device and able to accomplish

8:02 more so that allows you to use less

8:04 space in the facility and last but not

8:08 least the longevity so typically a retro

8:12 Metro device the life cycle will be

8:15 three to five years and

8:18 with um Cloud Metro the system that you

8:21 you get that um because of the

8:24 Innovation with the chipset because of

8:27 the Innovation that we decoupled the

8:28 power shelf as well as the fabric

8:31 capacity that allow for future

8:32 generation of chipsets so that extend

8:35 the lifetime from three to five years to

8:38 7 to 12 years

8:39 that's over double of the lifetime and

8:43 that really helps reduce the E-Waste so

8:46 you've talked about the power saving row

8:49 but what role does automation play in

8:51 improving sustainability in a Metro

8:53 Network I'm glad you asked so for

8:56 automation the way we see it is first

8:59 when with automation you can automate

9:02 tasks such as onboarding service

9:05 Assurance capacity planning things like

9:07 that and how does that relate to

9:09 sustainability well first when it comes

9:12 to configuration provisioning onboarding

9:15 and service experience typically or

9:18 historically you would need to send your

9:20 technician to the field which which is

9:24 basically the truck roll and by

9:26 automating this task that allows you to

9:28 reduce the amount of truck rows required

9:31 and that has direct impact and direct

9:34 reduction for any telco's carbon

9:37 footprint

9:38 secondly is that when it comes to

9:41 sustainability the way we see is not

9:44 only

9:45 um the the the the energy or the the

9:48 green but also the sustainability for

9:51 the people and the business so with

9:54 automation

9:56 um and AI Ops it allows people to be

9:58 able to accomplish more with the same

10:01 resources we talk about Metro networks

10:04 are going to grow five-fold in the next

10:07 five years and chances are that the any

10:11 Taco are not going to have five times

10:13 more people to do it which means

10:16 enchances are they are going to have the

10:18 same team of people and how to make sure

10:20 that Empower them to accomplish so much

10:23 more without burning out and having

10:26 giving them a good work-life balance

10:28 that is where automation comes in and

10:31 that is where AI Ops him really make a

10:33 difference

10:35 so surely it sounds like there are a lot

10:37 of ways that telcos can actually become

10:39 more sustainable thank you very much for

10:41 your insights with us Irene

10:43 you're welcome
