The traditional PID controller parameters are hard to tune timely under the rapid changes of the dynamic network circumstances, which affect the PID algorithm's control effects on network data flows. To alleviate the problem, a novel AQM algorithm based on PID controller is proposed, called the improved expert intelligent PID algorithm (IEI-PID). By combining expert knowledge with PID and adding more...
At present, most studies on the communication are based on simulation, but any theory needs to stand the test of the physical environment. This paper implements the embedding of PID AQM algorithm in software router-IPCop in the communication test network. And the comparison of results from NS2 simulation and the communication test network proved that the embedding method was correct. The method of...
Random Early Detection (RED) can effectively avoid transmitting congestion at routers, but RED can not provide bandwidth fairness. Different packet sizes are one of the reasons that damage fairness. RED routers provide little protection from some bulky data flows that use considerably more bandwidth than other flows in time of congestion. Modifying the formulas of calculating final packet-discard...
If TCP flows have smaller maximum-window sizes, the transmission rate of these flows will be controlled by rather maximum-window sizes than the drops from bottleneck link. So it is necessary to consider the effect of maximum-window size confined on studying the queue management in routers of the network. The formula of maximum discard probability for random early detection (RED) algorithm was derived...
