Soe, Sorry about jumping in but the solution to your problem may be to force the packet to be forwarded to the same ingress port by using the reserved port OFPP_IN_PORT.

However, sometimes that openvswitch need to relay other packets to other node for eg, if the wireless node receive that packet receives at port number 1 and that received packet is not intended to that node, that wireless node simply forward to its neighbor node. So the rules will be, in_port=1, dst_ip=other wireless node's ip, actions=output:1. In that case, OpenvSwtich will simply drop the packet instead of forwarding to prevent the looping problem. Therefore, the in_port number need to be logically changed. In openvswitch, we can simply install that rules by putting command " sudo xxxxx actions="load:0->OXM_OF_IN_PORT[]". If you know how to do that one, please let me know.

In OVS, we can simply put "load:0->OXM_OF_IN_PORT[]" this statement at action field. In RYU controller, how can i install that action. -- Best Regards, Soe Ye Htet Research Assistant (Chulalongkorn University) +66647240647 _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net <mailto:Ryu-devel@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/ryu-devel -- Best Regards, Soe Ye Htet Research Assistant (Chulalongkorn University) +66647240647 --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
