Evolution of the SDN Ecosystem with Open Source

Here comes Stratum which is an evolution of  switch data plane management. This approach leverages P4 and moves away from the classic OpenFlow protocol.

Here is what the ONF says of the project "Stratum is an open source project to develop a reference implementation for white box switches supporting all next generation SDN interfaces. It will provide a silicon-independent switch operating system that allows a switch to be controlled by a local or remote Network OS (NOS) via P4, P4Runtime and OpenConfig."
