摘要: TCP/IP網(wǎng)絡(luò)中有一些路由選擇和流量控制方法只能保證系統(tǒng)局部最優(yōu)。本文引入現(xiàn)代控制理論,提出通過(guò)對(duì)TCP/IP數(shù)據(jù)通信網(wǎng)非線性狀態(tài)控制模型進(jìn)行線性近似,并借助李亞普諾夫原理的途徑判斷數(shù)據(jù)通信網(wǎng)整體穩(wěn)定性的方法;在穩(wěn)定性的基礎(chǔ)上,證明了數(shù)據(jù)網(wǎng)最優(yōu)控制可以具有路由最短和路由不形成環(huán)路等性質(zhì)。

Abstract: 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 entir stability of date communication networks, based on the Lyapnovn Priciple and approxmation of linearized network state control model, which is a nonlinear one in the nature. Forthmore, we confirm the conclusions of TCP/IP network optimazation such as: the shotest path is available as well as the optimal routing will never from routing link loop and so on. -
