Buffer sizing for nonhomogeneous TCP sources

Abstract

Considering a single bottleneck model of TCP with a constant number of greedy and nonhomogeneous sources, and assuming that TCP timeouts do not occur, we establish necessary and sufficient conditions, related to the bandwidth delay product, to guarantee that the buffer will never empty. We also demonstrate by simulation that weaker conditions could be adequate to maintain high utilization in practice and discuss delay and packet drop rate implications. © 2005 IEEE.
