This tutorial is for developers with intermediate knowledge of the P4 language who are interested in using ONOS as the control plane. It is organized around a sequence of hands-on exercises that show how to build a leaf-spine data center fabric based on Segment Routing over IPv6 (SRv6). Exercises include activities such as:
- P4 implementation of basic forwarding behaviors (bridging and routing) as well as SRv6
- Writing P4 unit tests using the Packet Test Framework (PTF)
- Implementing an ONOS app providing the fabric control plane
