摘　　要：基于通信网络的传输原理,利用马尔科夫随机过程理论讨论了由单路由器构成的简单网络的建模问题.分析了TCP窗口四种变化状态的马尔科夫特性,给出了状态转移矩阵,得到了一个单路由网络模型.该模型反映了窗口变化同数据包丢包概率之间的关系,同时给出了队列长度和窗口大小之间的关系.The modeling problem of communication network with single-route is discussed based on the grounds of advanced stochastic Markov process theory. And the Markov characteristics of the 4 states of TCP windows are analyzed. The state transformation matrix is given, and the communication network model with single-route is obtained. The relationships between the window varying and the probability of pack-drop, as well as between the queue length and the window size, are reflected by the proposed model.
