FARED: Fast adapting RED gateways for TCP/IP networks

Abstract

Random Early Detection (RED) is a widely deployed active queue management mechanism to improve the performance of the network in terms of throughput and packet drop rate. The effectiveness of RED, however, highly depends on appropriate setting of its parameters. In this paper, we propose a Fast Adapting Random Early Detection (FARED) algorithm which efficiently varies the maximum drop probability to improve the overall performance of the network. Based on extensive simulations, we show that FARED algorithm reduces the packet drop rate and achieves better throughput than Adaptive RED (ARED) and Refined Adaptive RED (Re-ARED). Moreover, FARED algorithm does not introduce new parameters to improve the performance and hence can be deployed without any additional complexity. � 2012 Springer-Verlag.
