RESEARCHES ON ENTIRE STABILITY AND OPTIMAZATION OF TCP/IP NETWORKS
TCP/IP网络的整体稳定性和优化研究

In TCP/IP networks, some routing decision and flow control algorithms can guarantee only partitioned optimazation of networks. In this paper, we use modern control theory to develop a new method to judge the entire stability of date communication networks, based on the Lyapunov principle and approximation of linearized network state control model, which is a nonlinear one in the nature. Forthmore, the conclusions of TCP/IP network optimization are comformed, such as: the shortest path is available as well as the optimal routing will never form routing link loop and so on.
