Introduction

Stratum is an open source silicon-independent switch operating system for software defined networks. It supports a number of white box switches and exposes a set of next-generation SDN interfaces, including P4Runtime and OpenConfig/gNMI.

Stratum avoids the vendor lock-in of today’s data planes (i.e. proprietary silicon interfaces and closed software APIs) and enables easy integration of devices into operator networks. It delivers a complete white box switch solution to realize the ‘software defined’ promise of SDN.
