Simple Router

This README.md is written by Yuan Zhou

Introduction

Write a simple router with a static routing table. The router receives raw Ethernet frames, processes the packets just like a real router, then forwards them to the correct outgoing interface.

Get Started

First, clone this repository to the home directory of Mininet and cd into it.

Prerequisites

You need python-dev to install ltprotocol, which is needed for our POX module. Run the following commands.

sudo apt-get install python-dev
git clone git://github.com/dound/ltprotocol.git
cd ltprotocol
sudo python setup.py install

You need to install the POX module by

./config.sh

Start Mininet

Start Mininet emulation by using the following command

./run_mininet.sh

Setup and Start POX

Start a new terminal, checkout the POX version that we use in this assignment

cd /home/mininet/pox
git checkout f95dd1a81584d716823bbf565fa68254416af603

Then start the POX

cd ~/simple-router
ln -s ../pox
./run_pox.sh

Start the Router

Open yet another terminal (the third one). Run the binary file of the solution (correctly implemented router)

./sr_solution

Develop

Edit files in the router directory, compile and run the router by:

cd router
make
./sr
