1. There is two types of delete commands. OFPFC_DELETE and OFPFC_DELETE_STRICT. 2. The OpenFlow message you use is OFPFlowMod, which you used to install flows. Look at the OpenFlow spec for how to construct those messages. I think you can use the out_port field in this case. 3. Grep for OFPFC_DELETE under ryu/app. You'll see some examples. -- IWAMOTO Toshihiro ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ryu-devel
