Abstract

The embodiment of the invention provides a TCP acceleration proxy method and device, a satellite ground station and a readable storage medium, and relates to the field of satellite communication. When it is detected that TCP data is cached in the TCP data buffer area, whether the sending buffer queue has the residual length or not is judged; if yes, the size of the remaining length is obtained, the target TCP data are read from the TCP data buffer area according to the size of the remaining length, then the target TCP data are stored in the sending buffer queue, and the target TCP data are sent to the satellite link through the sending buffer queue. And if not, re-judging whether the sending buffer queue has the residual length after the preset time length. In this way, the matched target TCP data is read according to the residual length of the sending cache queue reflecting the residual bandwidth of the satellite link, data backlog is avoided, the data in the sending cache queue can be transmitted by the real-time transmission bandwidth of the satellite link, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of satellite communications, and in particular, to a TCP acceleration proxy method, device, satellite ground station and readable storage medium. Background technique [0002] In recent years, with the continuous development of satellite communication technology, the application of satellite communication has become more and more extensive, and making full use of satellite bandwidth resources has become a hot topic in the field of satellite applications. Since the satellite link is a high-latency link, in order to improve the throughput and bandwidth utilization of the satellite link, TCP (Transmission Control Protocol, Transmission Control Protocol) acceleration came into being. User online experience. [0003] In the prior art TCP acceleration proxy method, the satellite ground station will continuously receive user data and forward the user data to the satellite link for transmission to the satellite stati...
