Sway: Traffic-Aware QoS Routing in Software-Defined IoT

===========================================================

This directory contains some starter code for the POX + Mininet setup used in Sway.

Installation/ Usage :

• Step 1: Clone this repository to your home directory.
• Step 2: You should have two directories, namely pox and mininet.
• Step 3: The pox/ext/sway contains the code for a simple reactive forwarding module built on top of the POX SDN controller.
• Step 4: To launch the reactive forwarding application, simply cd into the pox directory and run $ ./pox.py sway.startup
• Step 5: The mininet directory contains a simple custom topology. To launch it, cd into the mininet directory and run $ sudo python topology.py

Adding Functionality :

From here on, you can add various functionality according to your requirements. I have intentionally kept the code simple so that it is easier to understand and modify. Some ideas for enhancements are:

• The fnss library can be utilized to read in various network topologies from sources such as CAIDA and Internet Topology Zoo.
• Since mininet/topology.py and sway/reactive_fwd utilizes the networkx library, you can utilize various algorithms present, such as Dijkstra, Bellman-Ford, K-shortest paths, etc.
• The OpenNetMon module can be utilized to measure link delay, bandwidth etc. for QoS applications.
