【摘要】在本文中，设计了一个针对TCP/IP网络的基于SNMP网络设备的MIB信息采集系统。这个系统采用三层模型进行设计，最底层负责SNMP中基本对象编码、定义，与设备连接通信等；中间层在底层的基础上定义了MIB对象，负责OID与MIB对象间的转换，分析MIB信息文件以生成MIB树型结构，单个MIB变量信息查询等功能；顶层，即界面层则在中间层的基础上实现了用户界面。设计中运用Java语言，运用Java-Applet技术，其存储在一个运行有Tomcat的服务器上，以接受用户请求，使用户能在任何一个支持Java运行时的浏览器上进行使用。系统在设定设备IP地址及端口号和读写共同体名后能查看相应设备的基本信息。在加载MIB信息文件后可自动生成MIB树型模式，用户则可根据需要查看设备各项细节，亦可进行设定操作。查看基本信息时，用户可自行选择是否自动刷新，这将有助于节省网络带宽和系统资源。

MIB information collection of network equipments based on SNMP 
【Abstract】In this text, I designed a MIB collection system of network equipments based on SNMP at the network of TCP/IP. This system adopts model of three layers to be designed, the bottom is responsible for basic SNMP objects’ code, connect communication with network equipments, etc.; The intermediate level has defined MIB target on the basis of ground floor, is responsible for the conversion among OID and MIB target, analyse MIB information file in order to turn into MIB tree type structure, such functions as individual MIB variable information inquiry, etc.; The top floor, namely the interface storey has realized user’s interface on the basis of the intermediate level. It is developed using Java language, and the usage Java- Applet technique, it is saving on the server that running the Tomcat, to accept the customer requests, and anyone with a browser supporting Java run time can use it. The system can look into basic information of the correspond equipments after setting the equipments IP address , port numbers , reading and writting community.After adding the MIB information document, the system can build a tree mode based on the document and then the customer then can look into various details of equipments according to his demand, and also can do some settings.While looking into the basic information, the customer can by oneself choose whether renovate automatically, this will contribute to the save of network bandwidth and system resourceses.
