Pseudo-rate TCP: a congestion avoidance scheme with nearly optimized fairness and throughput

Abstract

As the bandwidth requirement on the Internet grows, the efficiency of networking protocol becomes an important concern. This paper proposes a so-called pseudo-rate TCP, which features both better fairness and higher throughput than TCP Vegas by exponentially increasing the window size to a derived bound. The pseudo-rate TCP avoids the typical problem that sources with shorter round-trip times always get better chance in allocating the bandwidth. We discuss two key mechanisms designed for pseudo-rate TCP, and compare its performance with TCP Vegas through system simulation. (C) 1999 Elsevier Science B.V. All rights reserved.
