Cloud Nets: Recent Episodes
DriveNets
Failure recovery is a very big issue when it comes to AI clusters because there are always failures and when the failure come, it’s a big thing because you need to stop the calculation, go back to the last checkpoint. You lose a lot of time and money and resources that are spent idle and and wasted time. And the networking part is crucial in order to create a fail.
Congestion demands attention, otherwise it can result in higher latency and packet loss. The main dilemma around congestion is around avoidance or mitigation. We’ll look at how scheduled fabrics make sure that AI infrastructure is lossless and predictable rather than bringing additional technologies to mitigate the congestion, but do not avoid it
Why is cell-based fabric is so much better than the alternative when it comes to Ethernet for AI fabric or AI infrastructure.
Chassis and Clos, which is better?
From the perspective of scale, absolutely Clos topology outranks a chassis. From an operational standpoint, a Clos topology would mean that you will need to manage a lot of boxes and that's a bigger headache than managing a single device, a chassis, one stop shop. But from a Capex standpoint, a Clos topology prevails over chassis. Looking at the alternative, Distributed Disaggregated Chassis (DDC), it takes the same scalability factor of a Clos, the operational aspects of a chassis and even when you look at the cost side of things, from an operational standpoint, DDC operates as a single device. Then from a Capex standpoint, DDC operates or works as white boxes.
We're going to talk about KDDI, one of Japan's major Tier 1 operators. They recently announced that they implemented DriveNets Network Cloud solution in its network and they are very satisfied. They are talking about huge TCO advantages, about 46% saving in power and 40% savings in rackspace, etc.
Let's hear about KDDI and why is this deployment, a major deployment, of Network Cloud so important?
How can a disaggregated network solution provide benefits in terms of Total Cost of Ownership to service providers in a long term perspective
What are three things we can learn about Network Cloud in real world network operations.
Today we're going to talk about recovering from major faults, those things that keep you up at night.
DriveNets hosted a panel for analysts and media at MWC23 in order to explain its work and hear from industry leaders on progress for disaggregated networking. Members of the panel included Igal Elbaz, SVP and network CTO at AT&T; Jean Louis Le Roux, executive vice president for International Networks with Orange; Cayetano Carbajo, VP for core, transport and service platforms with Telefonica.
Today we're going to talk again about AI networking, and we will provide the solutions for the challenges we mentioned last time. With the fast growth of AI workloads, network solutions need to be ready to resolve issues including having a flexible and online architecture, being able to scale and maintain performance at scale, and having a field proven rock-solid solution.
What are the challenges of AI Networking?
We’re going to talk about AI, and specifically about AI networking. we want to talk about the challenges behind the AI infrastructure, because AI ML training, it’s very compute, intense task.
What are the main challenges in AI networking that companies like the Hyperscalers that are going into this market now needs to resolve?
We’re talking about some myths about disaggregated distributed chassis or Network Cloud. The myth about Network Cloud and this architecture in general is just a one off. The myth about the operational headache. And the myth about that it’s a fairly complex architecture.
DriveNets Network Cloud, changes the operational and economic model of the network, allowing it to scale capacity and services much faster while increasing service provider profitability.

We're talking about operations because usually when you talk to operations people about disaggregated and cloud-native systems, they do not like it. Since it's multiple vendors, it's multiple building blocks, it's a new thing to learn. And operations people will love to stick to what we have. But surprisingly enough, bringing the Network Cloud into your network actually means better operations, simpler operations.

Now that we've established that building a Network Cloud cluster is easy, let's talk about what happens afterwards because the operations guys are the ones that having been doing the hard work all those years, after the engineering plans and installation.
How do you build a cluster with Network Cloud? The cluster is granular and built upon multiple boxes, so you can bring them with you, and find vacant places in existing racks to put it into and not have to have a dedicated rack for a new gigantic crowd.
Today we’re going to talk about the cloud, or specifically why cloud does not matter at all. You don’t need to worry or think about the underlying infrastructure, the hardware, the upgrades, the versions, the connectivity, etc, etc. And these are all transparent to you. This all looks like a cloud, something that you know that is there, but you don’t really care what happens in it. So this is why the cloud does not matter.
Today we are going to talk about the things we fear the most...End of life...which we, as network engineers, fear the most. So what do we do about end of life? With DriveNets' Network Cloud you have multiple hardware options, the entire cluster is built upon standard interfaces so it's very easy to replace or to upgrade the cluster with any box that adheres to those interfaces, and you can repurpose boxes in an exhausted cluster without the need for forklift.

So what do we need to know about this move from 400 to 800? 800 is real. It's here, you can almost buy it. It's a fairly smooth transition, having forward compatibility with the stuff you buy today. The Network Cloud, the architecture, is agnostic to the interfaces or form factors.
Today we are going to talk about DNOS, the DriveNets Network Operating System. Why is DNOS important and how it's different than just your ordinary network operating?
Let's talk about ISSU, In Service Software Updates. What's new and how actually DriveNets can eventually make you upgrade your network without service.
We're going to talk about TIP DDBR, Telecom Infra Project Distributed Disaggregated Backbone Router and the RFI that went out. And hey, we got a ribbon, so we need to talk about it.
Watch the episode.
Let's talk about optical modulation and some basic features of optics that us networking guys need to know.
Watch the CloudNets episode
Let's about the optics that go into your router. We're going to talk about ZR and ZR+ and open XR and stuff like that.
So this is what you need to know about optics coming through the router: longer reach, leaner infrastructure, and lockout or the non lock in nonproprietary open system that allows to choose different vendors for your infrastructure.

Why is it important?
As a newcomer into the networking space, the DriveNets disaggregated approach faced doubts.
Explore how service providers have experienced the benefits of network disaggregation
With regulators more and more talking about zero carbon emissions, going green and sustainability are high priorities. Service providers are feeling the push and need to put things into place in their operations. Why is sustainability so important for network operators?

Networks today need to scale, requiring more and more capacity. They also need to introduce new services in order to stay competitive and to satisfy the needs of the hungry subscribers. How do we deal with a data tornado?
https://drivenets.com/resources/episode-11-scale-smart/
Standardization is especially important for disaggregated networks, since software and hardware come from different vendors, the interconnect between those needs to standardized. But how does it reflect in the network cloud world?
Edge compute, edge networking, Telco Cloud. All those buzzwords mean one thing: the content, the essence of the network, the cloud instances are moving to the edge, to the edge of the network, to the edge of the cloud. That means they want to be closer to the subscribers.
Disaggregation of hardware and software, software based cloud-native instances, etc, these all have a dramatic effect on your total cost of ownership. So, when you go to disaggregation, the Network Cloud, you save a lot of money.
Today, we're going to talk about high availability in the Network Cloud, because in spite of what you may think, the Network Cloud Infrastructure presents higher availability than the traditional chassis.
