A DUAL PROXY APPROACH TO TCP PERFORMANCE IMPROVEMENTS OVER A WIRELESS INTERFACE

摘要

A dual split-TCP connection (Fig. 1) for improving throughput in a data transmission system containing a wireless link is described. A pair of gateways are individually associated with a subscriber unit and a base station on opposite sides of the wireless link. The gateways respectively from spaced TCP proxy terminations for a pair of terminal machines, such as an end user machine and a server, between which data packets are exchanged over the system. Transmision over the wireless link itself employs an optimized wireless protocol or another non-TCP protocol such as UDP. Such elimination of the use of TCP over the wireless link minimizes delays attributable, e.g., to false readings of congestion on such link and the consequent unnecessary triggering of TCP congestion control/slow start mechanisms.
