Abstract

In this paper we investigate the reliability of Random Early Detection (RED) gateway. For the RED buffer behavior a new model based on Markov chains is offered. The reliability of RED gateway is defined by an average rate of accepted packets. We examine the impact of RED tuning on the reliability by taking into account stick-slip nature of traffic intensity. The goal of the proposed model is to improve RED buffer management by using a technique of traffic intensity change detection.
