Python Network Programming

How to do it...

Mininet consists of a few network topologies that are predefined. You may define your own topology. In this recipe, we are using tree topology, which is probably the most common and the most basic network topology. We ping one emulated host from another emulated host.

Listing 9.2 emulates a simple network with a tree topology:
