Improving the Performance of Interactive TCP Applications Using Service Differentiation
Overview Interactive TCP applications, such as Telnet and the Web, are particularly sensitive to network congestion. Indeed, congestion-induced queuing and packet loss can be a significant cause of large delays and variability, thereby decreasing user-perceived quality. This paper studies different packet marking schemes and handling mechanisms in the network. For marking packets, two approaches are considered. First, it look into application-based marking, and show how the protection of Telnet traffic against loss can eliminate large echo delays caused by retransmit timeouts, and how, by limiting packet loss for Web page downloads, their delays can be significantly reduced, resulting in enhanced interactivity. Second, it considers differentiation based on TCP state, where a marking algorithm is presented that prioritizes packets at the source, based on each connection's window size.
