     106= Prerequisites: Installing Mininet-Optical =
     107
     108Before starting this tutorial, you will need to have Mininet-Optical installed. If it isn't installed already, you can follow the Installation and Walkthrough instructions at https://mininet-optical.org.
     109
     110The tutorial topology and a sample configuration script should be found in ~/mininet-optical/examples/cosmostutorial.py and ~/mininet-optical/examples/config-cosmostutorial.sh. If they are not there, you may need to fetch and check out the appropriate branch from github and install it using make install.

     332Mininet-Optical's Terminal is the equivalent of the ToR switch
     333which contains Ethernet interfaces as well as WDM transceivers.
     334
     335Instead of using a Cisco-style CLI to configure it, we use its
     336default REST API.
