Notice of Violation of IEEE Publication Principles - TCP-Equivalent Window-Averaging Rate Control Scheme

Abstract

New rate control schemes are necessary for Internet streaming flows to smoothly use the available bandwidth. To equally share the Internet bandwidth with existing TCP flows, these schemes should meet the TCP-equivalent criterion, i.e. the same rate as TCP under the same network conditions. This work proposes a window-averaging rate control (WARC) scheme to sends packets at the average rate that a TCP flow may use over a fixed time interval. Considering the TCP rate only over a fixed interval leads WARC to forget the historical loss condition more quickly than other schemes and thus have faster increasing rate when additional bandwidth becomes available. The analysis and simulation demonstrate that WARC does approach the equivalent bandwidth as TCP, exhibit the faster convergent behaviors, and meanwhile have smoother rate than existing schemes.
