In this talk we discuss Match, a generic interface for capability discovery and state management of a match-action based packet processing pipeline, and how this can be used to accelerate Open vSwitch. Match fills a role on a programmable platform where optimized pipelines outside of OVS can be leveraged, such as optimized software pipelines and hardware acceleration devices. We will share some of the integration done with OVS, including the ability for OVS to leverage external TCAM and hash lookup resources, the ability for OVS to offload VXLAN encap / decap, and the ability to control the packet forwarding of packets going in and out of a hardware virtual functions (VFs) into VMs and containers.

This talk continues on the discussion we had in the last OVS conference, in the last pair of LinuxCons, and some discussions at the P4 conference on a runtime for programmable pipelines.
