Mininet linear topology: 200 switches

- [Instructor] If I specify 10 switches, and pingall, that means I have 10 switches connected back to back. Now, this is not real world, this is just for fun to show you what's possible. It's very, very easy to create these topologies in Mininet using a single command. So, as you can see over here, here's switch 10 with host 10 connected to it. Just by running a single command, I can create these larger topologies, so let's specify 200 switches. That's gonna create 200 switches, each having one host connected to it, in other words, we gonna have 200 hosts and 200 switches. So, click Reload. It's busy discovering where all the devices are, so do a host 1 ping host 200 as an example. The ping succeeds. Actually you might be able to hear that my PC is revving up here trying to manage this network of so many hosts. So, if I zoom in, you can see right over here there's a host connected to switch one, and right over here there's a hots connected to switch 200. All I wanna show you is it's…
