⁠Stratum - Enabling the era of next-generation SDN

Copyright 2018 Google LLC

Stratum is an open source silicon-independent switch operating system for software defined networks. It is building an open, minimal production-ready distribution for white box switches. Stratum exposes a set of next-generation SDN interfaces including P4Runtime and OpenConfig, enabling interchangeability of forwarding devices and programmability of forwarding behaviors. Current support includes Barefoot Tofino and Broadcom Tomahawk devices, as well as the bmv2 software switch.

⁠Documentation

⁠Getting Started with SDN / P4 / Stratum

If you're completly new to the world of P4 and are looking for step-by-step instructions with batteries included, the NG-SDN⁠ tutorial is a good starting point. For material more focused on P4 as a language, have a look at the p4lang⁠ tutorials. Finally, there is the "Software-Defined Networks: A Systems Approach" book (HTML⁠) for comprehensive coverage of SDN. Also see the chapter about Stratum⁠ in it.

⁠Source code

This repository contains source code for a reference implementation of the P4Runtime and gNMI services, that serve as the hardware abstraction layer for a network switch. It has been successfully prototyped at Google, running on production hardware on a data center network subsystem.
