Abstract:
At an SDN controller executing using a processor and a memory, a tracing packet is configured with a default value in a tag field. The tracing packet is inserted from the SDN controller into the SDN at a switch in the SDN. A returned packet and a port identifier is received at the controller, from the switch, the returned packet including a modified content in a location of the tracing packet that is different from the tag field. The port identifier corresponds to a port of the switch on which the switch received the returned packet from an middlebox. A function of the middlebox is identified by analyzing a modification applied to the modified content by the middlebox. The function of the middlebox and a location of the middlebox in the SDN are saved. The location includes the port identifier and an identifier of the switch.

Claim (Index 4):
The method of  claim 2 , further comprising:\n assigning a highest execution priority to the set of packet forwarding rules at the switch such that when the switch receives any packet, the set of packet forwarding rules is executed prior to executing any other rule at the switch relative to the received packet.
