Adaptive control method of network data flow for QoS providing

Problem of Quality of Service (QoS) providing in computer networks in case of uncertainty of data transferring processes is examined. Method of random early detection (RED) for congestion avoidance in networks is analyzed. Modification of adaptive RED (ARED) is offered. This modification consists in adjusting parameter, that are used during determination of average queue length in router´s buffer, on a base of queue stability condition and dynamic adjustment of maximum probability of packets drop in case of congestions. Reducing of networks parameters amount, that are used for adjusting of active queue management algorithms, on a base of their ranking towards availability and importance, is offered.
