open source reference implementation
for white box switches supporting
next-generation SDN interfaces
Stratum is an open source, silicon-independent switch operating system for software-defined networks
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:
- Optional forwarding pipeline programmability
Stratum is designed to support a variety of use cases including:
CLOUD SDN DATA PLANE
Leverage Stratum in Custom SDN Networks. Google is committed to production deployment of Stratum leveraging this use case.
CLOUD SDN FABRIC PLATFORM
A complete open source solution for next-gen data center spine-leaf fabrics.
OPERATOR EDGE CLOUD PLATFORM FOR 5G MOBILE & MORE
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.
