Abstract

Embodiments of the present invention provide a data transmission method, system and proxy equipment. The transmission method includes: establishing a TCP connection between the client and the Internet server, the proxy device interacts with the client in a wireless manner, the proxy device interacts with the Internet server in a wired manner, and the proxy device obtains the initial sequence number and response in the corresponding direction Serial number, and based on this, the data forwarding between the client and the Internet server is completed, and there is no need to establish independent TCP connections with the client and the Internet server, which will not affect the quality of service of the wireless network.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method, system and agent equipment. Background technique [0002] The client establishes a Transmission Control Protocol (TCP) connection with the Internet server through the mobile communication network. Wherein, the client and the mobile communication network are connected through a wireless link, and the mobile communication network and the Internet server are generally connected through a wired network. Due to the obvious time-varying characteristics of the wireless link, the data transmission rate and packet loss rate between the client and the mobile communication network change drastically with time. At this time, the TCP congestion control method for the wired network will be used to adjust the transmission strategy. However, due to the difference in transmission characteristics between wireless networks and wired networks, the T...
