Mininet Examples These examples are intended to help you get started using Mininet via its Python API. linearbandwidth.py This example shows how to create a custom topology programatically by subclassing Topo, and how to run a series of tests on it. scratchnet.py, scratchnetuser.py These two examples demonstrate how to create a network by using the lowest- level Mininet functions. Generally the higher-level API is easier to use, but scratchnet shows what is going on behind the scenes. udpbwtest.py This example shows how to run a test across an entire network, and monitor the output of a set of hosts in real time.
