Hi Ben, thanks for responding!
I am embedding multiple path information from source to destination in ip and mac headers So I am sending flow mod messages from the controller to mininet In I use a random number to select one among the n path information I have embedded in the headers I understood the control flow as a) The packet enters from switch from the host into the function "void ovs_dp_process_received_packet(struct vport *p, struct sk_buff *skb)" b) The actions get applied on these packets due to the function call "ovs_dp_process_packet_with_key(skb,&key,false)" (As far as my understanding does this . I am not sure whether Iam right here) c) I was thinking if skb contains the modified packet after the call to " ovs_dp_process_packet_with_key(skb,&key,false)" then i could extract the output port from the headers and do rest of the processing On Mon, Jan 26, 2015 at 3:49 AM, Ben Pfaff <b...@nicira.com> wrote: > What's your actual goal? > > On Mon, Jan 26, 2015 at 12:50:16AM +0530, Sree Vidya S D wrote: > > Thanks a lot Ben! > > > > But I need little more help over here. > > > > How do I get my modified packet ?
