A Model ForWindow Based Flow Control Packet-Switched Networks

Recently, networks have increased rapidly both in scale and speed. Problems related to the control and management are of increasing interest. However, there is no satisfactory tool to study the behavior of such networks. The traditional event driven simulation is slow when the network speed is high. The time driven simulation is against the nature of packet-switched networks. As Transmission Control Protocol (TCP) is the most widely used transport layer protocol, and it uses window based flow control mechanism, classic queuing theories involving Markov Chain assumptions are not applicable.
