The code you want to look at is mostly in lib/ofp-util.[ch] and ofproto/ofproto.c. The former is an abstraction layer over OpenFlow message encoding and decoding. You will want to modify it to encode and decode the 'importance' field. The latter actually handles all the OpenFlow messages flowing through a switch. You will need to modify it to actually use the importance field. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
