An analytical model for the binary feedback scheme

An analytical model is developed for performance evaluation of the binary feedback scheme for congestion control in data communication networks. The relationship between the change of window site and the length of the source queue is discovered by introducing an auxiliary virtual packet blocking mechanism. Based on this relationship it is demonstrated that the system throughput can be computed locally by monitoring the traffic in the source node. The model is solved by a new mean valve analysis algorithm. The significance of this study is the provision of a uniform modeling approach which can be generally applied to other feedback control mechanisms. Finally, numerical examples are given to demonstrate the methodology and the validity of the analytical results.<
