[nox-dev] How to get the network traffic state

[星言 墨虚]

Hi all,

Sorry to bother you.

I run a router module of NOX to forwarding data which include TCP packet and 
UDP packet.
I want to inspect the rate speed of TCP and UDP packet separately.
What should I do?
And could ofp_flow_stat collect the data what I want?

Thanks very much.
