Keynote: Model-driven Mechanisms for OpenFlow Device Interoperability
Curt Beckmann (Brocade / Chair of the ONF’s Open Datapath Working Group)
The SDN movement is based on abstracting the data plane to allow device-independent control. The 1.0 version of OpenFlow provided a basis for decoupling in simple situations. But establishing a common interoperable interface for device abstraction has proven more difficult for complex networking using the simple OpenFlow framework. A new richer model-driven framework that describes forwarding behavior in OpenFlow terms promises to bring practical device independence to complex networking. This talk will describe the framework, some challenges, and recent progress at the ONF and in OpenDaylight.
