Mastering Networks with Mininet VM

Building a massive network doesn't require a single piece of hardware. You just fire up

the Mininet VM, login, and type sudo mn. Instantly, you’ve got a fully

functional network with switches and hosts running right inside your laptop. It’s wild because

these nodes are actually isolated processes with their own interfaces. You can run connectivity

tests with pingall or switch up the entire architecture from a single switch to a complex tree

topology just by changing one line of code. It is literally the ultimate cheat

code for mastering software-defined networks without destroying your bank account.
