Described is a method of processing data packets in a communications network. The method comprises receiving a first data packet of a data packet flow from a network device and determining an instruction set for processing said first data packet. A flow key for said first data packet is determined. The first data packet is processed according to the determined instruction set. The method includes receiving a subsequent data packet and determining if a flow key of said subsequent data packet matches said flow key of said first data packet. If yes, the subsequent data packet is processed using the instruction set determined for said first data packet.

Method to accelerate packet detection rule (PDR) matching and data packet processing in a user plane function (UPF) module in a communications network

A method and apparatus for transporting packets over a wide area network (WAN) in a communications network are provided where the WAN comprises a plurality of interconnected nodes including at least a first communication node, a second communication node and a WAN controller node. The method comprises establishing virtual private network (VPN) tunnel connections on communication links between some or all of the communication nodes comprising the WAN, using a non-stream-oriented transport layer protocol to establish a non-stream-oriented association for each VPN tunnel connection, and, on receiving a packet connection from a source device at said first communication node, encapsulating packets from said packet connection into one or more non-stream-oriented associations between the first communication node and the second communication node to thereby transport said packets from the source device to the second communication node. The WAN controller node communicates to the first communication node a selection of links or routes for packet transport to the second communication node. The first communication node selects the one or more non-stream-oriented associations for encapsulating packets into from a plurality of non-stream-oriented associations established on the links or routes communicated to said first node by the WAN controller node.

Method and an apparatus for establishing secure, low latency, optimized paths in a wide area network

A method for setting-up a tunnel connection for transporting data packets over a high latency network connection in a communication network comprises the step of, at a module or node configured on a tunnel connection initiator side of the high latency network connection, using a non-TCP connection to encapsulate a set-up connection message for sending to a module or node configured on a core network (CN) side of the backhaul network to offset-up a data packet transport tunnel connection between the initiator side of the high latency network connection and core network (CN) side of the high latency network connection.
