Receiver-Window Modified Random Early Detection (RED-RWM) Active Queue Management Scheme: Modeling and Analysis

In this paper, we present a mathematical model for a novel TCP congestion control approach called Receiver-Window Modification (RWM). RWM could be used with any of the present Active Queue Management (AQM) schemes, such as Random Early Detection (RED), Adaptive Random Early Detection (ARED), and BLUE queues to reduce congestion at the ingress and gateway routers. We extend the work done on stochastic modeling of RED-ECN gateways to RED-RWM gateways. Using this model, we provide a weak convergence theorem for the number of connections; thus leading the way to more relaxed configuration of RED-RWM gateway parameters. We use a Monte Carlo simulation method to compare outcomes of our mathematical model with those of NS2 simulation experiments.
