METHOD AND DEVICE FOR IMPLEMENTING TCP TRANSMISSION

摘要

Disclosed are a method and a device for implementing TCP transmission, aiming at improving the transmission performance of TCP connection crossing a 3G wireless network and increasing the bandwidth utilization rate of an air interface. The method for implementing TCP transmission comprises: a Transmission Control Protocol (TCP) proxy receiving data sent by a server, caching the data locally, and feeding an acknowledgment character ACK back to the server, the data being data required to be sent to a terminal through the TCP proxy after the TCP connection is established between the server and the terminal; performing data transmission through a wire between the TCP proxy and the server, and performing data transmission through the air interface between the TCP proxy and the terminal; and the TCP proxy sending the locally cached data to the terminal with full bandwidth, the full bandwidth referring to the maximum quantity of data capable of being borne by a transmission channel between the TCP proxy and the terminal.
