Big Switch stole many of the networking headlines this week when it announced its Switch Light software release. Switch Light, based on the open source technology Indigo, can be used on commodity white box switches to create an OpenFlow-based switch than can be used as part of a software defined network implementation. One of the elements of the press release that I felt flew under the radar, was that Extreme Networks would be the only “mainstream” network vendor that was committing to this reference architecture for a rack switch.
Extreme will later this year introduce its Slalom switch, which will be an optimized SDN switch running the thin virtual network software. Slalom will complement Extreme’s Open Fabric portfolio that has a number of SDN-capable switches in both stackable and chassis-based forms. Slalom will be a 48-port Gig-E Ethernet switch that will be based on a “white box” solution.
