Extreme Networks Addresses Scale Issues with its Open Fabric Software-Defined Networking

Listen to the Podcast

January 14th, 2013

No matter where an IT architect looks they are confronted with scaling issues and many times one solution creates another problem.  To address increasing VM density many are expanding broadcast domains with flatter 2-tier architectures only to get bogged down in broadcast issues.  To scale virtualized networks the industry offers VXLAN, but that moves L2 scaling into a multicast-scaling problem.  Software-Defined Network and in particular OpenFlow offers a good approach for provisioning and control but introduces flow oriented architecture scaling issues of its own.  I discuss scaling challenge with Shehzad Merchant Chief Technology Officer at Extreme Networks.

Lippis Intro/Analysis @ : 00:10 sec

Question 1

@ 1:35 sec: Shehzad: Let’s first start with Extreme’s view of 40 and 100GbE.  How is Extreme incorporating it and why?

Question 2 @ 3:50 sec: Forwarding table architecture and size define logical networking scale.  Extreme recently introduced UFT or Unified Forwarding Table.  What is it and how does it work?

Question 3 @ 6:35 sec: Extreme has partnered with Big Switch Networks to address network visualization scale via its Big Tap and Big Virtual Switch.  Can you talk to this solution?

Question 4 @ 8:51 sec: Can you sum up all the initiatives that Extreme has under way to deliver on its Open Fabric architecture for clo
