Introduction

base code is from dfshan's dpdk-switch

i will add (multi-priority) multi-queue for every port.

i will add some policy on it.

i will change some code implement.

i will add RL policy(use RL to manage buffer).

This is a l2 learning switch based on DPDK.

Features

• ECN marking
• Fine-grained queue length monitoring
• Shared Memory
• (multi-priority) multi-queue
• AWA Policy
• DT Policy
• EDT Policy

Requirements

• DPDK == 17.08.1
• libConfuse >= 2.7

How to run it

1. Install requirements

2. Build and Setup DPDK library, including

   • Correctly set environment variable RTE_SDK and RTE_TARGET
   • Insert IGB UIO module, setup hugpage, bind Ethernet device to IGB UIO module

3. Create a configuration file (and change configurations in it if needed)

   $ cp switch.conf.example switch.conf

4. Build and Run the application

   make

   sudo ./build/app/main -c 0x7 --log-level=7 -- -p 0xf
