P4-Play

Record something useful information and experiments on P4.

Usage

This repository will record some information about how I learn P4 from hardly without any knowledge about networking. So it will have some basic concept about networking command in Linux, mininet API learning, and some P4 spec knowledge I read from p4.org/specs, like PSA, P4_16. All the practices will base on P4_16 to illustrate.

• Repository Structure
  • Installation
    • About install the p4 develop requirement environment. See more under this folder.
  • P4-playground
    • multiswitch
      • Using mininet with python API support
      • Contain some experiments with P4 and multiple switches scenario.

        • load balancing (ECMP)
    • run-directly
      • Using ip command to build the network environment with single switch.
      • And then using simple_switch with P4 directly.
    • run-mininet
