This week Extreme Networks joined the list of vendors that have unveil their software defined networking (SDN) strategies. In my opinion, it’s one of the better SDN announcements in that it was both broad and deep, highlighting some of Extreme’s long-standing strengths.
One of the fundamental tenets of an SDN is that it enables programmability of the network. Accomplishing network programmability across its product line was relatively easy for Extreme as its XOS operating system has had a high degree of programmability for years now. I remember talking to Extreme about “programmability” about five years ago, but there was little interest in it then. The company had a few strong proof points but the interest certainly wasn’t near what it is today.
Specifically, what the company announced was support for multiple OpenFlow controllers, including NEC and BigSwitch. Additionally, Extreme announced a Quantum API-based plug-in for OpenStack. The combination gives developers, cloud providers and others interested in SDN a number of programmability options, including APIs, SDKs as well as a handful of Extreme-designed, purpose-built applications.
