网络管理论文：基于SNMP协议的Agent告警软件的设计与实现 【中文摘要】近年来,随着网络规模的扩容,异构程度地不断增加,网络技术有了长足的进步,现代网络已经演变成为一个复杂、多元化的“大系统”。现代网络发展进程中,安全的、可靠的、开放的、综合的、经济的网络管理;网络资源的合理优化配置;运行状态的实时监控已经成为必不可少的奋斗目标。随着网络技术的飞速发展,当今的网络环境正趋于复杂化,大型化。网络环境的正常、稳定运行是当前网络发展的重中之重。对网络环境的监控、测试、分析和告警,是网络稳定运行的重要保证。本文主要是利用SNMP技术,开发符合网络存储产品的网管代理软件。在文中通过SMI、MIB库、SNMP标准规范等多个方面详细阐述了SNMP协议的结构、组成及其应用。本次开发的Agent告警软件主要功能是当存储产品出现故障后通过SNMP协议发送告警信息通知管理站;同时能够支持不同网络环境和域之间的对接,能够满足可扩展性、过载保护、高可用性、长时间稳定运行等非功能性需求。该软件的告警内容主要分为硬件告警、RAID卡告警、操作系统告警、备份软件报警四部分。软件主要设计思路是通过模块化的开发方式,分模块对代理进行开发。文中详细分析了软件的功能需求、并针对相应的功能进行详细的设计。通过对SNMP引擎的阐述,完成了对代理核心的分析。后续通过代理工作流程和MIB库的分析,完善了整个告警代理软件的功能。最后在先前设计的基础上,成功利用net-snmp开发工具实现了网管告警代理软件的开发。 【英文摘要】With the rapid development of network technology, today’s network environment is to become more complicated, large-scale. The normal network environment, network development and stable operation of the current top priority. The network environment, monitoring, testing, analysis and alarms, is important to ensure stable operation of the network.This paper is the use of SNMP technology to develop products in line with network storage network management agent software. In the text by SMI, MIB database, SNMP standards and other aspects of SNMP protocol described in detail the structure, composition and application.The development of the network management agent software main function is to store the product after failure to send alarm information via SNMP management station informed; the same time be able to support different network environments and between the docking domains to meet the scalability, overload protection, high availability of long and stable operation and other non-functional requirements. The software is mainly divided into hardware alarm warning, RAID card alarm, alerting the operating system, backup software alarm in four parts. Main design idea is to software development through a modular way, sub-module of agent development. Analyzed in detail the software functional requirements, and the corresponding functi
