Congestion control with the double and hysteresis threshold in ATM networks
Sang Gug Jong, Yong Ohk Chin · 2002
A priority scheduling algorithm with double threshold and a traffic control mechanism with hysteresis effect are proposed. The double threshold priority scheduling is studied based on the minimum laxity threshold (MLT) and the queue length threshold (QLT). The hysteresis effect traffic control is specified by the hysteresis effect QLT and traffic rate control. According to the simulation results, it can be shown that the proposed dynamic priority scheduling has a better processing performance than the existing MLT and QLT algorithm. The results also demonstrate that the QLT with hysteresis effect and traffic rate control with the hysteresis effect enhance the performance in comparison with those of single threshold.
