The random early detection(RED) algorithm is an important queue control mechanism in router presently. Based on analyzing this algorithm, several improved algorithms are introduced briefly. The formula of calculating the data stream drop-rate in RED is mended, and the Nth degree RED algorithm is brought forward.This algorithm testified by the simulation software NS-2 can increase the throughput and reduce the drop-rate of data flow effectively.
