摘　　要：主动网络是一个可编程的网络计算平台，它为用户提供了可编程的接口，允许用户或应用在网络内部定制自己的数据包处理方法。网络中传送的数据包是由用户数据和数据处理程序共同构成的主动包，主动包经过网络节点转发处理时．通过执行主动包中的程序代码来决定数据包的转发行为：传统网络管理不能发挥主动网络的分布式计算能力，不适应主动网络管理。本文讨论了一种基于节点的、用主动报文实现主动网管功能的主动网络管理模型，重点对管理报文的结构、转发机制和主动包路径转发算法进行了分析。Active network is a programmable platform which owns distributed calculating ability. Tt provides some interfaces for programmers to call. Within an active network, programmers can customize their own methods to process data packages. Data package in an active network contains both user information and process cod. When an active data package arrives at a network nod, it will be transmitted to next one, the whole course is controlled by the commands which exist in an active data package. Distributed calculating ability is not offered in a traditional network, and as a result, active network management is not available in such kind of environment. IN this paper, we talk a network model over which is based on active message management, and the management message structure, transmission mechanism, arithmetic of transmission path choosing are adequately analyzed and discussed.
