CONTROLLING A TRANSMISSION CONTROL PROTOCOL WINDOW SIZE

摘要

A method and apparatus for controlling a Transmission Control Protocol (TCP) window size for data sent from a TCP sending node via a mobile network. The TCP sending node receives a TCP request message from a remote node requesting a TCP data stream. The TCP request message includes a parameter relating to conditions in the mobile network and/or the presence of a TCP proxy node. The TCP sending node uses the parameter to determine an initial permissible window size for a TCP slow start mechanism. It can then send a TCP data stream towards a TCP receiving node using the slow start mechanism starting with the initial permissible window size. This allows the slow start phase to start with a higher initial window size.

1. A method of controlling a Transmission Control Protocol (TCP) window size for data sent from a TCP sending node via a mobile network, the method comprising, at the TCP sending node:
receiving from a remote node a TCP request message requesting a TCP data stream, the TCP request message including a parameter relating least one of conditions in the mobile network and a presence of a TCP proxy node; using the parameter, determining an initial permissible window size for a TCP slow start mechanism; and sending towards a TCP receiving node a TCP data stream using the TCP slow start mechanism starting with the initial permissible window size.
