摘要
主动网络是一种新型的网络体系,不仅可以传送数据包,而且还可以执行数据包中特定的运算任务。主动网络为用户提供了可编程的接口,用户可通过网络中的节点动态地注入所需的服务。而传统网络管理不适应主动网络管理,因而不能发挥主动网络的分布式计算能力。讨论了一种基于节点的主动网络管理模型,分析了该模型的结构、管理机制和设计要点,并对网络拓扑发现和流量进行了分析。
Active network is a new framework where network nodes not only forward packets,but also perform customized computation on the packet flowing through them. It provides a programmable interface to the user where users dynamically inject services into the intermediate nodes. However, the traditional prototype of network management does not accommodate to the management of active networks, it cannot utilize the distributed copulation capabilities that active networks provides. This paper analysed the structure and mechanism of the active network management system, introduced a pattern of active network management, and studied the structure, management mechanism, design outline and each connection of the management system. The paper also studied the network topology discovery and traffic.
