Enabling the era of next generation SDN

Stratum is an open source project to develop a reference implementation for white box switches supporting all next generation SDN interfaces. It will provide a silicon-independent switch operating system that allows a switch to be controlled by a local or remote Network OS (NOS) via P4, P4Runtime and OpenConfig.

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.

The Stratum project broadens the scope of SDN to include full lifecycle control, configuration and operations interfaces.

Envisioned as a key software component of SDN solutions of the future, Stratum implements the latest SDN-centric northbound interfaces, including P4, P4Runtime, gNMI/OpenConfig, and gNOI. It does not embed control protocols, but instead is designed to support either an external Network OS or to work with NOS functions running on the same embedded switch.

Stratum: Open Source Thin Switch Implementation

  • 5 Leather US5 5 RTRY Wedding Novelty Kids amp;Amp; Winter Comfort Office amp;Amp; Career Party UK4 Evening Leatherette Platform Casual EU37 Big Spring Patent Fall Women'S Boots Dress Open source streamlined implementation for a thin switch implementing next generation SDN interfaces
  • Defines a “contract” defining precisely the forwarding behavior supported by the data plane, expressing this in the P4 language
  • Network OS can be external (for SDN scenarios) or embedded in the same switch when used in traditional switch/router implementations

Supports full lifecycle control and management, including:

  • Configuration
  • Control
  • Operations
  • Optional pipeline programmability

Stratum will be designed to support a variety of use cases including:


Leverage Stratum in Custom SDN Networks.  Google is committed to production deployment of Stratum leveraging this use case.


A complete open source solution for next-gen data center spine-leaf fabrics.
