p4-researching

My Researching work on P4.

Notice: Current testing environment are not based on the latest version of P4. You can using the scripts under docker/ to build a docker image for these tests. And all the examinations are running on software switch, a.k.a "bmv2", and I use simple_switch_grpc as demonstration.

Environment Setting

Before getting started with P4 programming, we need a P4-capabled environment for running those scenario. And this repository summarize several methods and provide several way to accomplish.

• Build sucessfully with Ubuntu 16.04.05:
  • Installation scripts - P4
  • (Optional) Installation script - ONOS
• Also you can build your own test environment in docker:
  • Installation for Docker
  • Build your own P4 testbed with docker image
• Using P4 virtual machine (via Oracle VirtualBox):
  • P4.ova download : Completed P4 environment (Updated at: 2018/9/30).
  • P4 (only with deps).ova download : For develop environment of P4-related tools.

About this repository

P4 (with Mininet)

• More details under src/
• Contain lots of P4 practices and scenarios, which based on the open source software switch - BMv2 and mininet, with P4Runtime support to finish those work.

Notice:

v0 users: You can found some tutorials in branch:tutorials

v1 users: Use the master branch directly.

P4 with ONOS

Learning how to build an ONOS application which support P4. See more detail under onos/

Tracing P4Runtime

• Look here, have some diagram about P4Runtime's dependencies.

Build network namespace

• If you don't want to use mininet, you can use ip netns instead.
• Under net/, have a demo script for building several network namespace.

Learning Materials

• Provide some learning resources about Networking, which located in course/.
• Welcome to contribute!
