Signposts On The Roadmap Out To 10 Tb/sec Ethernet

The world of Ethernet switching and routing used to be more predictable than just about any other part of the datacenter, but for the past decade the old adage – ten times the bandwidth for three times the cost – has not held. While 100 Gb/sec Ethernet was launched in 2010 and saw a fair amount of uptake amongst telecom suppliers for their backbones, the hyperscalers decided, quite correctly, that 100 Gb/sec Ethernet was too expensive and opted for 40 Gb/sec instead.

Now, we are sitting on the cusp of the real 100 Gb/sec Ethernet rollout among hyperscalers and enterprise …

Worth Reading: Time is not on your side

Many of the presenters, like Truman Boyes of Bloomberg and Peyton Maynard-Koran of EA, discussed the idea of building boxes from existing components instead of buying them from established networking vendors like Cisco and Arista. The argument does hold some valid ideas. If you can get your hardware from someone like EdgeCore or Accton and get your software from someone else like Pluribus Networks or Pica8 it looks like a slam dunk. You get 90% to 95% of a solution that you could get from Cisco with much less cost to you overall. —Networking Nerd

Worth Reading: Improving metrics in cyber resiliency

With the growth in cloud computing, businesses rely on the network to access information about operational assets being stored away from the local server. Decoupling information assets from other operational assets could result in poor operational resiliency if the cloud is compromised. Therefore, to keep the operational resiliency unaffected, it is essential to bolster information asset resiliency in the cloud. To study the resiliency of cloud computing, the CSA formed a research team consisting of members from both private and public sectors within the Incident Management and Forensics Working Group and the Cloud Cyber Incident Sharing Center. —The Cloud Security Alliance

Network Longevity – Think Car, Not iPhone

One of the many takeaways I got from Future:Net last week was the desire for networks to do more. The presenters were talking about their hypothesized networks being able to make intelligent decisions based on intent and other factors. I say “hypothesized” because almost everyone admitted that we aren’t quite there. Yet. But the more I thought about it, the more I realized that perhaps the timeline for these mythical networks is a bit skewed in favor of refresh cycles that are shorter than we expect.

Software Eats The World

SDN has changed the way we look at things. Yes, it’s a lot of hype. Yes, it’s an overloaded term. But it’s also the promise of getting devices to do much more than we had ever dreamed. It’s about automation and programmability and, now, deriving intent from plain language. It’s everything we could ever want a simple box of ASICs to do for us and more.

But why are we asking so much? Why do we now believe that the network is capable of so much more than it was just five years ago? Is it because we’ve developed a revolutionary new method for making chips that are ten times Continue reading

IDG Contributor Network: How intent-based networking is transforming an industry

The fundamental principles of intent-based networking have been present for years, but only recently has this phenomenon grow to its full size today, where it stands to upend modern industry and business practices. So what exactly is intent-based networking, and is it really so marvelous to warrant the recent renewal in interest and support it’s gained?A brief foray into intent-based networking shows that, while it’s a very complex technology, it’s rather easy to grasp a basic understanding of it. Furthermore, a look at what some of today’s top companies are doing with this tech, and some ruminations about what they plan to do in the future, shows just how significantly intent-based networking can reshape modern markets.To read this article in full or to leave a comment, please click here

What is controllerless Wi-Fi and who needs it?

It’s no longer necessary for enterprises to install dedicated Wi-Fi controllers in their data centers because that function can be distributed among access points or moved to the cloud, but it’s not for everybody.While the arrangement is often referred to as controllerless, that is a misnomer; there is still a control plane, it’s just not located in a dedicated device.The traditional data-center deployment of a controller really isn’t a strict necessity for enterprise WLAN use any more, according to Farpoint Group principal Craig Mathias,+RELATED: 5 Wi-Fi analyzer and survey apps for Android; The future of Wi-Fi: The best is yet to come+To read this article in full or to leave a comment, please click here
