Hi All,

I am new to Openflow and  I have few questions/clarifications.

Lets assume there are some switches in sequence A-B-C.

a) Is there a way for the controller to know which switch has how many rules
installed ? using the openflow protocol ?

b) some of these rules will cause some cpu utilization as they may require
use of slow path. Is there a way to know the load on the openflow switch cpu
using the openflow protocol ?

c) how will the controller decide - how much degree of rule aggregation /or
fine grained rules is practically good for the switch ?

Regards,
Vishal
