Data Center Master Classes

I’m doing a series of three master classes through Juniper on various DC fabric topics—

Join Juniper’s Russ White, a widely published 30-year network engineering veteran, in a three-part masterclass exploring the data center. Choose from classes on data center fabric, physical topologies, or data center security.

You can register here.

From the schedule—

  • Class 1: Data Center Fabric, December 2, 12 PM EST
  • Class 2: Physical Topologies, January 13, 12 PM EST
  • Class 3: Security in the Data Center, February 10, 12 PM EST

Link State in DC Fabrics

If you don’t normally read IPJ, you should. Melchoir and I have an article up in the latest edition on link state in DC fabrics.

To make a case for linkstate protocols in DC fabric underlays, an extensive examination of the positive and negative aspects of BGP—and the other available protocols—is essential. Ultimately, it is up to individual operators to decide which protocol is “the best” for their application, a decision based on business and operational—as well as technical—reasons.

On the ‘net: Internet Consolidation

Did you know that today Video, gaming and social media account for almost 80% of the world’s internet traffic? The change in the composition of traffic has been accompanied by a dramatic change in the way content is delivered to the internet user: ISPs and transit providers have diminished in number and importance as the power and profile of a few Content Distribution Networks has increased as content is being pushed closer to the edge. But isn’t that just competition at work? What are the long-term consequences of such a change? In the second episode of our three-part series on “Internet Consolidation”, we talk to Russ White, co-host of The History of Networking and The Hedge podcast and a distinguished infrastructure architect and internet transit and routing expert.

On the ‘net: RFC1925 Rule 11

Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works. In other words, the present and future might not repeat the past, but it will certainly rhyme. The number of times this has happened in the world of networking technology is almost beyond counting—mostly because there are only a few real problems to solve in every area of networks, and there are only a few real solutions to those problems.
