These are notes from a “Elephants and Mice” on elephant flow detection and mitigation in software switches. The result of tests demonstrate that integration between overlay and underlay networks has value. This solution uses low cost networking components and highlights some competitive positioning against Cisco ACI.

Received an email about this article Chambers: Cisco Is Going To Crush VMware – Business Insider. The title strongly suggests that John Chambers said “Cisco is going to crush VMware” but it’s a lie.

Early last year I drew a strategy map of all the elements in a Software Defined Ecosystem for a client. I drew another one a couple of weeks back to explain how the current vendor focus on controllers, and specifically, OpenDaylight is changing the nature of the market. The comparison is striking.

Some people have pointed out the Internet BGP table is now at 500,000 IP Routes. I'm must say I'm disappointed. If you people don't hurry up and blow this to a million entries, we will never get decent routers and greater bandwidth in the carrier backbones.

It is often said that there are only problems in the design of IP Routing protocols. Propagation – how routes are notified to all elements on the network. Expiration – how to detect and notify that routes are no longer valid. But most people quickly realise that silent third problem – recursion. […]
