Hi Yusuke,
Thanks for the response!
Yes that helps but what I was aiming at was if packet_in has source UDP
port is (say) 500, I was to push a flow for source UDP port 500-599. In
other words if I get a packet in with source UDP port x, I want to install
a flow for x to x+99. In short wildcard mask of 100. Is this possible with
Ryu?
Regards,
Vinay Pai B.H.
