Scenario

Given 3 flows:

• f1: DST:10.0.0.1:5001 -- 5Mbps
• f2: DST:10.0.0.1:5002 -- 15Mbps
• f3: DST:10.0.0.1:5003 -- 25Mbps

Objective

When some of the flows are not using the bandwidth available for them, the other flows get a bit more than they are originally assigned.

Limitations and scenario

As this project is designed to be a demo to a university course, there are many things hardwired into the code.

These specifications are mostly related to the topology and the specific flows. These are namely:

• Use the reference Mininet VM available from their website for running the mininet part of this experiment.
• The mininet VM must have the following IP address: 192.0.2.20
• The machine (supposedly the host machine) needs to have the following IP address: 192.0.2.1
• The controller is set up to handle those specific three UDP flows, at the moment, using TCP or other flows are not supported.
