Abstract

The invention relates to an interval type congestion control method for routers based on changeable load, which overcomes the over sensitivity of the existing RED(Random Early Detection) method to parameter setting and network environment and improves the threshold value in an RED from a point to an interval so as to obtain a new interval type RED method, namely, IRED (Interval Random Early Detection) algorithm, which obtains more strong robustness and better control under the load changeable network environment. Compared with the RED method, the performance of the system can be obviously improved by applying the method of the invention to carry out congestion control for routers, which leads to the decrease of loss rate of data packets, improvement of throughput of a network system and enhancement of stability. The method of the invention is a convenient and practical interval type congestion control method for the routers based on changeable load with excellent performance.

Description

technical field [0001] The invention belongs to router queue management and congestion control methods, in particular to a router interval congestion control method based on variable load, and belongs to an innovative technology based on the variable load router interval congestion control method. Background technique [0002] The Internet based on the TCP / IP protocol has become a global information infrastructure since the 1990s. Numerous data streams in the network meet at the router, which brings a great burden to the router. Although with the development of science and technology, the capabilities of network equipment continue to increase, and the network bandwidth continues to grow, but the development of hardware always lags behind the growth of demand. When the demand for any resource on the network exceeds the total available resources at a certain moment, A bottleneck will be formed at the resource, causing the queued packets to fail to be sent in time, the buffer ...
