Abstract
A networking and application system for handling the data communications protocols in the mobile packet core network. General Packet Radio Service (GPRS) Tunneling Protocol (GTP) has a control plane for control signaling (GTP-C) and a data plane for user data (GTP-U). A GTP Switch interfaces with Serving GPRS Support Node (SGSN) and/or serving gateway (S-GW). The GTP Switch provides Interment Protocol (IP) address manipulation to hide the topology of distributed control plane and data plane instances. The GTP Switch also implements dynamic node selection to route the control signaling and data plane traffic to different instances, hosted on separate servers, thus enabling higher flexibility in the network routing path optimization and scalable and elastic handling of the data traffic.
