A Brief Introduction To OpenFlow
, November 14, 2011 OpenFlow is a specification now managed by the Open Networking Foundation, which defines the functions and protocols used to centrally manage switches via a centralized controller.Naturally, any critical system will have to be built with high availability in mind, and this requirement is not lost on OpenFlow controller vendors. The HA functions are not part of the Openflow protocol definition and will have to be implemented independently of the protocol. I'd expect to see HA implemented in other than active/standby, but how HA will actually be implemented will vary by vendor.
