Abstract
A method for linking Packet Detection Rules (PDRs) for optimizing throughput of combined Serving Gateway (SGW)/Packet Gateway (PGW) architecture is disclosed. In one embodiment the method includes, determining a SGW and a PGW are co-located on a system and when the SGW and PGW are co-located on a same system then performing a Packet Forwarding Control Protocol (PFCP) session lookup for an uplink packet at the SGW; determining which PDR to use for sending the uplink traffic; using the PDR to remove any tunneling protocol header; checking the PDR to determine if the next hop is local; when the next hop is local, then finding the PGW PDRs for this FTEID; identifying a PGW PDR matching with the current packet; performing any packet encapsulation; and after performing any optional header checksum calculations, sending the packet.
