对分组交换网非平稳过渡过程的路由选择问题进行了分析.从系统控制论的角度,在多业务流多链路网系统环境中建立了描述信息包从源端到目的端传输的全过程和网络节点分流过程的状态空间模型;根据李亚普诺夫系统稳定性理论,对多个传输链路的利用率函数G(·)和节点分流矩阵R~d的过渡过程特性进行了分析,推导了其稳定过渡条件,从一个新的侧面,提出了分组交换网路由选择协议设计中应注意的问题.
This paper analyzes the routing problem of non-stationary transition of packet-switched networks.From the point of view of system control theory, the whole process of describing packet transmission from source to destination is established in multi-service and multi-link network system environment and According to the Lyapunov stability theory, the transitional characteristics of the utilization function G (·) of multiple transmission links and node transition matrix R ~ d are analyzed. From a new aspect, we put forward some problems that should be paid attention to in the design of packet-switched network routing protocols.
