2019 OCP Global Summit

This talk will provide an update on Stratum -- a next generation, thin switch OS that provides silicon and hardware independence -- that was first introduced at the 2018 OCP Summit. Stratum adds new SDN-ready interfaces from the P4 and OpenConfig communities to ONL that enable programmable switching chips (ASICs, FPGAs, etc.) and traditional switching ASICs alike. We will describe how Stratum can leverage SAI’s programmable model (and flexible P4 architecture) for consistent control and management and explain how Stratum can help enable enhanced data plane programmability and telemetry for control planes, including SONiC. Finally, this talk will cover how the community has generalized Google’s seed contribution for additional whitebox targets, and demonstrate Stratum on a fabric of OCP devices controlled by an open source control plane.
