Open Networking Foundation – Stratum

Stratum™ is an open source silicon-independent switch operating system for software-defined networks. Stratum exposes a set of next-generation SDN interfaces to enable the interchangeability of forwarding devices and the programmability of forwarding behaviors.

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 that realizes the ‘software defined’ promise of SDN with configuration, lifecycle control, and operational interfaces.

As a key software component of SDN solutions, Stratum implements the latest northbound interfaces, including P4Runtime, gNMI/OpenConfig, and gNOI. It does not embed control protocols but instead supports an external Network OS or works with NOS functions running on the same embedded switch.
