Simulation and Exploration of RCP in the networks
Changhua He · 2003
RCP (Rate Control Protocol) is a rate-based congestion control algorithm, which can reduce the flow duration for small size files comparing with TCP slow start mechanism. Before transmission the sender and the routers will interact to achieve an optimal rate, in order to minimize the flow duration. We simulate and explore RCP in the networks with M/Pareto traffic. The result shows the optimal rate depends on the background traffic load and incoming traffic load of the bottleneck link. Furthermore, RCP works very well because some error in the optimal rate won’t influence the flow duration greatly. Theoretically we work out the expression for queue size of a single queue with M/General traffic when the transmission rate is greater than the link capacity, and we describe a method to calculate the upper bound of the queue size when the transmission rate is less than the link capacity. Based on this, we explain the simulation results when M/General is specified as M/Pareto process. 1.
