摘　　要： snmp在基于tcp/ip的网络中具有重要的地位，然而传统的snmp管理软件大多是基于c/s结构的，并且是集中式的管理，这必然为网络管理带来了不便。随着网络的不断发展，网络规模不断扩大，网络的复杂程度也在不断的增加，这迫切的需要一种新型的可以满足各种网络管理功能的管理系统。web技术的出现解决了这一难题，将web技术与snmp相结合的网络管理能够允许管理人员通过www的方式去监测他们的网络，使用任何一种web浏览器，在网络任何节点上方便迅速地配置、控制以及存取网络的各个部分。wbm（web－based management）是网管方案的一次革新，将使网络用户管理网络的方式得以大大改善。 本文在详细分析snmp协议的基础上首先论述了传统的snmp网络管理模型的工作方式，指出其不足之处。然后通过代理技术将web技术与snmp网络管理技术结合，提出了一种更为方便实用的基于b/s结构的分布式管理模式，实现了一个基于web服务的网络管理模型swnms，并对该模型的具体实现进行相关的讨论。 该模型实现了网络拓扑的发现，具有一定的网络管理功能，初步开发了基于snmp的web分布式网络管理系统，实现了配置管理、性能管理、故障管理等功能。本文最后提出了一些该模型有待进一步研究的问题，如与corba、移动agent技术的结合问题，指出该模型的良好发展前景。 SNMP plays an important part in network management. But because the traditional SNMP software which is of the type of centralized management is based on the C//S structure, it is not convenient for the network management. With the development of the network, the scale and the complexity of network increase continuously. So a new kind of management system must be brought forward to meet the need of network management. The technology of Web can resolve the problem easily. The network management which combines the technology of Web and SNMP allows managers to administrate their network via WWW. The manager can use any form of Web Browser to perform the fast configuration and the control of any part of the network at any computer as he likes. WBM/(Web-based Management/) is a reform of network management. It helps the managers to administrate their network more easily. This thesis discusses the traditional SNMP management model based on the detailed analysis of SNMP protocol, and points out the shortage of management. Then by the combination of the Web technology and the SNMP network management technology using agent technique, a new distributed management model SWNMS based on the B//S structure which is more convenient for the network is brought forward. Also the implementation of this model is discussed in detail. The model realizes the discovery of network topology, and it has the function of network management. It is a distributed network management system of web based on SNMP and it realizes configuration management, performance management and fault management and so on. At the last of the thesis, some questions that need to be studied further have been brought forward, such as the combination with CORBA and mobile Agent. The thesis also points out the good developing prospect of the model.
