Iam trying to implement source routing in openflow with Floodlight controller and mininet.
I came across this mailthread regarding the same https://mailman.stanford.edu/pipermail/openflow-discuss/2011-April/002075.html I think I have proceeded as mentioned in this mailthread and embedded the port numbers in the ethernet protocol fieldof the action types. Precisely I have edited the mac headers with the sequence of port numbers through which the packet should pass. I have created a linear topology with 4 nodes in mininet h1---(1)S1(2)----(2)S2(3)---------(2)S3(3)--------(2)S4(1)----h4 and try pinging from h1 to h4 In the controller it edits the mac headers when an icmp packet is received..so I create a packet out message with mac headers edited for the packetin message corresponding to the icmp request.(the macheaders now contain 2 3 3 1 wrt this topology) Can you please guide me what is the next step Iam supposed to do ? >From my understanding Iam supposed to sent this packet back to the switch. can anybody please explain how will the switches on the route handle this packet further ?? -- --
