Abstract

The invention discloses a TCP congestion control algorithm based on adaptive parameters. The method comprises the following steps of: during network data transmission, as the number of congestion windows increases, enabling a network to enter a congestion avoidance phase from a slow start phase; if retransmission timeout occurs in the congestion avoidance phase, determining that the network generates congestion and beginning to execute the TCP congestion control algorithm based on adaptive parameters, and dynamically controlling the sizes of the congestion windows and a slow start threshold value by setting the adaptive parameters; determining whether the network is recovered from the congestion by detecting whether the congestion windows are in a threshold range, if not, continuing executing the congestion control algorithm until the network is recovered from the congestion. With the adaptive parameters, the TCP congestion control algorithm enables the network to adaptively adjust congestion window values and the slow start threshold value according to an actual situation so that the network can get rid of congestion quickly and the utilization rate of the network is improved and vigorous network jitter is avoided.

Description

technical field

[0001] The invention relates to the technical field of computer network transmission control protocols, in particular to a TCP congestion control algorithm based on adaptive parameters. Background technique

[0002] According to statistics, if the retransmission event occurs in the web server, overtime retransmission accounts for 70%, and in common video browsing websites, overtime retransmission also accounts for about half. In the specific data transmission process, network congestion will seriously affect the performance of data transmission, and the processing strategy for overtime retransmission largely determines the transmission performance of the network.

[0003] In the prior art, there are already many technical solutions for network congestion control. For example, the application number is: CN201310002460.3 discloses a TCP congestion control method based on the throughput change rate ECN mechanism. Since the main operation of this method is in On...
