Modified RED Algorithm Based on Sampling Period

In dynamic networks Random Early Detection(RED) algorithm is sensitive to parameters, as wq etc.A Modified RED(MRED) algorithm is proposed, which discards low-pass filter and introduces a parameter freeze_time.This algorithm is simulated in two scenarios:"large delay and changing load","mixture flows of TCP and UDP".Experimental results show that in dynamic networks MRED algorithm achieves higher throughput and lower end-to-end delay, it can control the instantaneous queue better, and shows good robustness.
