I just posted it to github here: https://github.com/castroflavio/ryu
Please take a look at the code (shortestpath.py). The most important parts
are the networkx SP computation and the topology discovery (ryu.topology).
Networkx is a python library to do graph operations.
We just finished the project, so I wasn't able to delete unnecessary info
there. Feel free to modify it and add your name to the list of
collaborators. Also, if you use our code as starting point I'd be extremely
glad if recognize it on your code.
It's a very simple code. If you still have doubts after spending some time
reading I'll be glad to answer your questions.
