Abstract
A method is implemented by a switch in a software defined networking (SDN) network to trace packets in a packet processing pipeline of the switch. The method includes creating a copy of a received packet to function as a trace packet. The method further includes, at each of one or more subsequent flow tables that the trace packet traverses, appending an identifier of that flow table to a recorded route of the trace packet and resubmitting the trace packet to that flow table to be processed without packet tracing. The method further includes sending, at an egress table, the trace packet to a controller along with the recorded route of the trace packet.
