A few weeks ago, I wrote a blog post defining what “open networking” really meant and how it should be defined. On Monday morning, one of the companies I mentioned in the blog, Pica8, announced its vision and reference architecture for software defined networks (SDNs). While I believe that we’re very early in the cycle for SDNs and most enterprises will look for fully integrated, complete solutions, large, network-centric enterprises, cloud providers and service providers will lean towards open, agile platforms to create competitive differentiation.
Pica8’s solution is designed to be a network development platform for cloud providers and includes a physical switch with an integrated hypervisor virtual switch and an SDN controller using OpenFlow 1.2 as the communications protocol between all of the components of the solution. The Pica8 PicOS operating system utilizes both the Open vSwitch 1.7.1 with OpenStack and the above mentioned OpenFlow 1.2 protocol and integrates with the Ryu controller designed by NTT, specifically for cloud providers.
