Using P4 on Fixed-Pipeline and Programmable Stratum Switches

Stratum is an open source network operating system (NOS)that provides a common implementation of P4Runtime and OpenConfig interfaces for white box switches. This demonstration will show an SDN leaf-spine fabric of Stratum-enabled white box switches managed by the ONOS SDN controller. The switching chips (ASICs)and platforms will come from different vendors, but they will share a common P4-defined pipeline and set of OpenConfig models.
