The Research of Adaptive Network Congestion Control Algorithm Based on AQM

摘要

Congestion control has been emphasis of network research. The researchers proposed some algorithm of congestion control in order to continuously reduce the packet dropping possibility, and improve the link utilization ratio. First the paper directed the user by comparing some typical AQM control algorithms, enabled them optimize the network transport performance using more reasonable control algorithm in different network environment. Finally the paper proposed a new congestion control algorithm,which by predicting the instantaneous queue length of next time to decide congestion. It can find the congestion at the earliest time and make the best of network resource. The simulation result shows the proposal can detect the congestion in time in the changing network condition, and make the output smooth.
