一种基于主动网络节点的分层管理模型研究

主动网络是一种新型的可编程网络结构,它为用户提供了可编程的接口,使用户可以对网络进行个性化的编程和设置,通过网络中的节点动态地注入所需的服务,但传统的网络管理已不能适应主动网络的管理.本文首先讨论了传统网络管理(NM)中存在的问题,分析了主动网络管理(ANM)体系结构与管理机制,重点讨论了一种基于节点为核心的主动网络分层管理模型,并分析了该模型的结构、管理机制、设计要点和各层关系,说明了此模型能够很好地适用于主动网络的特点和管理的需求.

A Study of the Hierarchy Management Model Based on Active Network Node

Active network is a kind of new programmable network architecture where network nodes not only forward packets,but also perform customized computation in the packet flowing through them.It provides a programmable interface to the user where users can customize the applications and set up network,and dynamically inject services into the intermediate nodes.However,the traditional prototype of network management does not accommodate to the management of active networks,or it cannot utilize the distributed computation capabilities that active networks provide.This paper analyses the problems of tradition network management(NM),the structure and mechanism of the active network management(ANM) system.It introduces a layered design pattern of active network management based on the kernel of management of active node.This pattern can take full advantage of initiative,dynamics and intelligence in order to realize the distribution of intellectual management in active network.This paper studies the structure of the management system,which is made up of network management node,active node(it is made up of managed node.)Local Mgrs SW,Modeler and Instrumentation,to monitor,set,analyze and control nodes.The paper expounds the management mechanism,design outline and each connection of the management system.In the end,this paper proves this pattern can adapt to the characters of active network and its management.
