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.

Stratum is now fully open source and available under the Apache 2.0 open source license. The source code can be viewed here:

To contribute to Stratum, both individuals and companies are required to submit a Contributor License Agreement (CLA). If your company is already a Partner Member of ONF, only a CLA Addendum is required.
