Extending Mininet to emulate containers

Mininet can leverage the applications installed in the server to attach them as processes to the hosts that it emulates. For example, see the following, a vim started from a host in Mininet:

$ sudo mn
*** Creating network
*** Adding controller
*** Adding hosts and stations:
h1 h2

mininet-wifi> h1 vim
