Hi, Douglas
Ryu has ofctl_rest.py, which is a sample application and provides REST
API to get flow statistics.
http://ryu.readthedocs.io/en/latest/app/ofctl_rest.html
I think it is better to use ofctl_rest.py than to implement your own
REST API in your app.
Thanks,
Fujimoto

Greetings I am a PhD student new to both Python and Ryu and I was
wondering if anyone could give me some advice.
I am using the Ryu controller program (L2DestForwardStaticRyu.py)
provided by Dr Grey Bernstein
(https://www.grotto-networking.com/SDNfun.html#programming-switches-with-ryu)
for shortest path computation for a full Mesh network in Mininet but
the example provided does not include REST which I require to be able
to collect flow statistics such as the flows in each router,
bandwidth, latency, etc.
Unfortunately I have been looking and with the exception of
(https://osrg.github.io/ryu-book/en/html/rest_api.html) which seems
overly specific, I am unable to find a good example that would allow
me to work out how to integrate REST into the above Ryu control program.
So if anyone can point me in the right direction or can provide some
examples, I would be most grateful.
Thank you for your time.
Best Regards
Douglas
