Troubleshooting Shortest Path and Topology Discovery on RYU

This post is a follow-up to Shortest Path forwarding with Openflow on RYU. I originally made this code to show how to use SDN to achieve one of the most basic things you can do in a network: shortest path forwarding.

Topology Discovery with Ryu

How can be openflow used to do topology discovery? Why would you want to do that? You might be interest in doing topology discovery on your topology for multiple reasons such as applying custom forwarding strategies from a centralized global
