Traffic Shaping and Steering for a Multipath Transmission Control Protocol Connection

摘要

There is provided a method of enabling traffic steering and shaping for subflows of a Multipath Transmission Control Protocol (MPTCP) connection, wherein the subflows of the connection are carried over a plurality of Radio Access Networks (RANs). The method involves determining that the device is communicating with an end host using MPTCP, obtaining network information relating to the device, and using the device-related network information to decide whether any traffic steering and shaping should be applied to any subflow of the MPTCP connection. Appropriate actions can then be executed in relation to one or more of the subflows of the MPTCP connection in order to implement the traffic steering and shaping decision.
