ONF Connect 2019

Stratum is a next generation network operating system (NOS) for white box switches. It is primarily focused on supporting machine interfaces (P4RT, gNMI and gNOI) to automate network operations and enable user defining network element behavior with P4.

Edgecore's Cassini platform unlike traditional white-box switches enables network operators to integrate the packet switching and optical technology worlds as well as easily extend and migrate existing metro and long-haul networks.

PLVision will share the results of extending the Stratum NOS with optical transceivers configuration for Cassini chassis. This integration project involved:
- Integration of ACO and DCO modules with the help of TAI library that provides an abstraction layer for optical data-source control; 
- Extension of Stratum's internal structures to support this new type of optical interfaces;
- Implementation of Appropriate OpenConfig models for optical interfaces and modules as well as exposure of these models to the control plane via gNMI.

As a result, Stratum is extended to support optical network equipment, enabling the support of Cassini chassis which is a key infrastructure element of ONF's ODTN exemplar platform.
