Guaranteed to be called before any of your other code executes. At the bottom of the file is a launch function.There are three main things going on in lab2.py: Your code into multiple modules/files (which is fine with me, but not This should be the only file you need to submit, unless you choose to divide Part 1: Getting packets to their destinations.įor your solution, you'll be editing the controller code: lab2.py. Small message to test connectivity), you can issue: For instance, if you want one host to 'ping' another (send it a Terminal, which will pop-up in a new window:Īs a shortcut, you can also issue some commands directly on the MininetĬommand line. Within Mininet, you can run commands at each host by invoking a Once both Mininet and Pox are running, you can issue commands to the virtual If present, it will define a set of policy rules for your switches Topology you chose (basichosts or k4hosts). Where is the file containing host information for the Mininet

pox.py openflow.discovery lab2 -hosts= -firewall= Sudo mn -controller=remote -custom k4fat.py -topo k4fat Sudo mn -controller=remote -custom basictree.py -topo basictree I've provided twoĮxample networks: a basic three level, singly-root tree and a k=4

When you invoke Mininet, you need to choose a topology. It shouldn't matter which one you start first. OpenFlow controller that will tell your switches what to do, and Mininet, the Once you're connected to the VM over ssh, you'll need to start Pox, the Two different terminals, but I recommend trying out the screen Mininet, and another to run the Pox OpenFlow controller. Note that you will need two terminals connected to the VM: one to run The VM is already configured such that you can connect to it by sshing It's much easier to connect to the VM via ssh with X11 forwarding turned on. So is a huge pain if you enjoy nice things like graphical interfaces. While you could work from within the new VM window that just came up, doing

Click import and wait a minute for it to complete.Īfter you've completed these steps once, you should see the your VM in the.

You should now be seeing 'Appliance settings'.

Choose: /local/CS91-mininet-base.ovf and push next once.

Go to File->Preferences, set your 'Default Machine Folder' to '/local', and.

Run virtualbox in a terminal or open it from within your favorite.

To get started, you'll need to import a copy of the starter VM image: You could also copy your VM image from /local on one machine to /local on another with scp. This means that if you want to move and work a different machine, you'll need to set up a new VM at the new location.

The /local partition on each machine is only available on that machine.

When you're done working on your VM, you should shut You should save your important lab files elsewhere to avoid data loss in theĮvent of a disk failure. Which is split across multiple disks for redundancy.

The data on /local is stored on a single disk, unlike your home directory,.

Major implications that you need to account for: Because Mininet requires a very specific softwareĬonfiguration, we'll be running it inside of a VM to make things easier.ĭue to storage space constraints, you'll need to store your VM images on Simulate small datacenter network architectures like the ones we've been Modification functionality to behave like a basic firewall. Next, you will add some packet inspection and Shortest-path connectivity between hosts across a network topology with

This will be a two-week lab with two parts.
