Why Deep Buffer Matters for Next-Gen Metro Networks?

00:04 Welcome to Juniper Cloud Metro AMA series, where we have

00:07 experts to answer your questions, any questions related

00:11 to next-gen Metro networks. I'm your host today, Irene Zhang,

00:15 Director of Product Marketing at Juniper Networks. Joining me

00:18 today is Peter Chung, senior product manager at Juniper.

00:22 Peter, welcome. Today we have a question about why deep buffer

00:27 matters for next-gen metro networks?

00:30 Yeah, that's a great question that most of you frequently ask.

00:33 So, why we need a deep buffer for our next generation of the

00:37 metro networks. Our foundation of the building block is try to

00:41 provide very common framework. So, basically, this common

00:46 framework will give you the very flexibility to provide a

00:49 different variation for the topology, you can have a ring,

00:53 you can have a hub-spoke or leaf-and-spine architecture.

00:57 So our vision to drive the Next-Gen Cloud Metro. Latency is

01:01 very important.

01:02 So we picked the merchant silicon based on the VOQ

01:06 architecture called Virtual Output Queue. which give you the

01:11 great benefit for the optimization from the silicon to

01:15 keep your power density, but in the meantime, we'll provide you

01:19 great latency.

01:20 So, how to balance between the VOQ performance capacity and the

01:26 able to support variation of topology. So, keep in mind, our

01:32 Cloud Metro not just support for the traditional Metro topology,

01:36 but also to support 5G.

01:38 So, you can picture your scenario, your 5G network have

01:42 the very low speed application, but try to limit your new Metro

01:46 100GE or even for 400GE up speed uplink. So now the deep buffer

01:56 is very important.

01:58 Thanks to the silicon evolution, the latest generation chipset

02:03 gives you the delicate on chip resource, and more importantly,

02:06 is to offer you up to 8G HBM to memory.

02:11 So, those kinds of new enhancement for the silicon and

02:15 overall density of the memory will be increased. So basically

02:20 with this kind of big powerful mechanism, we can guarantee end

02:23 to end of transmission. More importantly, how to handle a

02:27 symmetric of traffic flow, you can do the micro-burst

02:30 absorption.

02:31 Our ACX, the latest generation of the metro product family is

02:36 based on the most advanced version of the silicon

02:39 technology. It gives you the 8G buffer for here.

02:43 This is our checkpoint for support the very first step to

02:47 support the Cloud Metro. Thank you.
