[pox-dev] Multiple controllers

[Silvia Fichera]

Hi all,
I've a l3_learning controller that check if a TCP request connection is
valid.
In a tree topology I would like that this one checks only the edge switches
and, if the connection if valid, another controller will install flow rule
on the switches.

So, if I receive a tcp SYN packet first of all the switch talks to my
controller, it checks the "honesty" of the source:
- if it's not honest "install" a drop rule on the switch
- else I would that the switch forwards the connection request to the
regular controller that install flows.

How can I contact the regular controller from the switch?

Thank you
