Hi Andrej,
Sorry for the delay.
Your topology has a loop (triangle with 3 switches), right?
Unfortunately, rest_router is just a sample application for Ryu-Book, it does
not assumes the
connected topology has loops.
I guess the loop in your topology causes the broad cast storm, and rest_router
cannot handle it...
Thanks,
Iwase

Hi,
me and my colleagues are working on a school project using mininet and real test bed. We decided to
use RYU controller, because it has two main apps that we can use in our own app:
- ofctl_rest
-rest_router
We've got a topology of 3 switches (connect to each other, so they create a triangle) and 4 hosts.
We want to GET (really using rest GET) info about specific port on concrete switch. We want to get
this data with as small period of time as possible, so we choose to send GET to controller every 1
second. After a while, controller send only empty JSON, instead of info in it and can't be turn on
again (we have to reboot mashine).
Is there any possibility to check this kind of bug, or whatever it is?
Or, have you got any advice for this kind of situation?
Best regards,
Andrej Vaculčiak
