This talk describes how the OpenDaylight (ODL) NetVirt and GroupBasedPolicy (GBP) projects evolve toward a comprehensive converged solution for network control which can implement network services in a flexible and forwarder independent way. NetVirt and GBP are both network virtualization applications that are intended to support multiple northbound APIs, and southbound protocols and devices. Unfortunately, these two solutions were not built to interoperate. “Nirvana Stack” is a term used to describe a converged SDN stack for Telco environments comprising OpenStack, ODL, FD.io/VPP and OPNFV. The FastDataStacks project in OPNFV currently builds such a stack, but so far only uses GBP. We will provide an overview of the architectures for the current NetVirt and GBP solutions, and describe how groups from both communities have worked together to leverage existing designs and implementations to evolve toward a comprehensive and flexible converged Nirvana Stack.
