Description

We investigate the effect of TCP Explicit Congestion Notification (ECN) with a new response strategy that is more aggressive in the short term, but preserves TCP long term behavior, without modifying the router marking rate. A less aggressive ECN decrease gives more incentives for end systems to become ECN-compliant, as ECN serves as an early warning sign in this case. Our analysis and simulation results demonstrate the effectiveness of the new algorithm in improving throughput and reducing fluctuations. We model a multiple bottleneck scenario with various types of traffic, and evaluate the effect of a number of parameters, including TCP flavor, increase/decrease parameters, buffer size, and random early detection (RED) parameters.
