文中首先介绍传统SNMP网络管理系统结构并指出其在管理大规模异构网络时存在的不足,然后引入主动网络技术并对其在网络管理方面的优势进行分析,在此基础上提出一种基于主动代理技术的网络管理模型。重点描述作为该模型核心部件的主动代理的实现方法,对用于实现各种网络管理功能的主动报文进行设计。最后,给出一个例子进一步说明主动报文的封装技术,并对该网管模型设计中的相关问题进行进一步阐述。 This paper first introduces the structure of traditional SNMP network management system and points out its shortcomings in the management of large-scale heterogeneous networks. Then it introduces active network technology and analyzes its advantages in network management. Based on this, Agent technology network management model. It focuses on the implementation of the active agent, which is the core component of the model, and designs the active message for implementing various network management functions. Finally, an example is given to further illustrate the active message encapsulation technology, and the network management model design issues further elaborated.
