Stratum is an open source, silicon-independent switch operating system for software-defined networks

Green rage 819196 Polarized Blue Nike Boots Blue Blue 443 Boys' Coastal Football Nike Coastal 819196 rage Boys' 443 Blue Green Boots Polarized Football Blue Blue Backed by a broad spectrum of organizations from across the networking industry, Stratum 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. Stratum delivers a complete white box switch solution truly delivering on the ‘software defined’ promise of SDN.

Next Generation SDN Interfaces

Enabling full lifecycle control and automated network management

  • 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 forwarding pipeline programmability

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.

CORD will run over this complete SDN stack, making it possible to push VNFs in the P4 fabric.


Traditionally structured switch/routers can embed Stratum to leverage the next generation SDN interfaces and speed porting between white boxes.
