简单网络管理协议（SNMP：Simple Network Management Protocol）是由互联网工程任务组（IETF：Internet Engineering Task Force ）定义的一套网络协议。简单网络管理协议(SNMP)是一种应用层协议, 便于在网络设备间交换管理信息。它是TCP/IP协议簇的一部分，也是一个标准的用于管理IP网络上结点的协议。网络管理员使用SNMP监视网络性能、检测分析差错、配置网络设备，发现和解决网络故障, 并计划网络增长。本文主要介绍了SNMP/MIB有关理论基础知识和数据的采集原理，并针对MIB信息库的单个对象和表进行分析，用java编程实现了数据采集功能。-Simple Network Management Protocol (SNMP: Simple Network Management Protocol) is the Internet Engineering Task Force (IETF: Internet Engineering Task Force) defines a set of network protocols. Simple Network Management Protocol (SNMP) is an application layer protocol, to facilitate the exchange of management information between network devices. It is the TCP/IP protocols as part of the cluster is a standard for managing IP network node protocol. Network administrators use SNMP to monitor network performance, detection of errors, configure the network devices, identify and solve network problems, and plan for network growth. This paper describes the SNMP/MIB related to basic knowledge and principles of data collection and information base for a single MIB objects and tables for analysis, using java programming the data acquisition.
