A DUAL PROXY APPROACH TO TCP PERFORMANCE IMPROVEMENTS OVER AWIRELESS 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 stati on on opposite sides of the wireless link. The gateways respectively from space d 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., t o false readings of congestion on such link and the consequent unnecessary triggering of TCP congestion control/slow start mechanisms.
