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.
Build status (master): 
P4Runtime provides a flexible mechanism for configuring the forwarding pipeline on a network switch.
gNMI is a framework for network device management that uses gRPC as the transport mechanism.
SDKLT is used to program fixed-pipeline switches using the Tomahawk chip from Broadcom.

This repository contains source code for a reference implementation of the P4Runtime and gNMI services, that serves 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.
We provide a script to create a Docker development environment for Stratum.
To start the container, run the following in your stratum directory:
./setup_dev_env.sh
The script will build a Docker image using Dockerfile.dev and run a bash session in it. This directory will be mounted in the Docker image and you will be able to run git, edit code, and build Stratum / run tests using Bazel.
For more information, you can see a complete list of arguments by running:
setup_dev_env.sh -h
If you are using Docker on Linux, make sure that you can use Docker as a non-root user, otherwise you will not be able to run setup_dev_env.sh:
sudo usermod -aG docker $USER
