A PACKET FORWARDING CONTROL METHOD FOR TCP PERFORMANCE IMPROVEMENT IN MOBILE NETWORKS

摘要

PURPOSE: A packet forwarding control method for improving a TCP(Transmission Control Protocol) performance is provided to allow a user to use a smooth handoff method and a RED(Random Early Detection) buffer management method in a mobile IP(Internet Protocol) path optimization process. CONSTITUTION: A portable terminal forwards packets received from a terminal corresponding to a first FA(Foreign Agent) to a second FA via a buffer of a base station. The corresponding terminal does not catch an access point of the portable terminal. The base station manages the first FA. The base station determines a forwarding process or a discarding process for packets based on RED state information.
