You can write OpenFlow match fields to filter tcp/80 packets but OpenFlow isn't capable of handling TCP payloads. tcp/80 packets can be sent to a ryu controller via packet-ins and TCP payloads can be reconstructed in a ryu application but it would require some work and I'm not sure if OpenFlow is good for such a use case. -- IWAMOTO Toshihiro _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ryu-devel
