【摘要】 随着社会信息化进程的加快,网上新业务层出不穷,使得人们对网络接入带宽的需求持续增加。尽管主流接入技术从拨号逐渐过渡到速度更快的ADSL和以太网,但是这些技术并未克服最后一公里的瓶颈问题,而光纤到户FTTH正好实现了人们对网络宽带的追求。网络管理系统用以监视、控制并协调所有可管理对象。随着网络的发展,主机数量多、网络分布广、网络结构复杂。网络设备和主机设备由不同厂商供应,多种系统及网络协议并存。系统和网络维护人员有限,系统日常维护和管理相当困难,使得网络管理更加重要。简单网络管理协议SNMP 是目前广泛使用的一种易于实现的网络管理协议,得到众多厂家的支持和广泛使用,已成为网络管理领域中事实上的工业标准。本文所设计实现的网络管理系统实现对FTTH 网络进行网络拓扑、性能和故障管理。本文首先介绍光纤到户FTTH 的市场背景、光纤接入网基本概念和模型、网络管理标准、网络管理功能要求及FTTH 网络管理系统的现状。在进一步对SNMP 的协议的组成、通信模型、管理模型和FTTH 接入网的解决方案的相关知识讲解后,再对基于SNMP 的FTTH 网络管理系统进行系统分析、概要设计、详细设计和实现。更多还原

【Abstract】 With the fast information process of our society, more and more kinds of new business spring out in the Internet, which makes the need of access network bandwidth keep increasing. Although the much fast ADSL and ethic network are replacing the way of dialing, these technology can not solve the bottle neck problem of the last mile. However, the FTTH(fiber to the home) satisfy the people’s need of network bandwidth. The system of network management is used to monitor, control and harmonize all the administrable objects. With the development of network technology, the number of hosts in network is becoming bigger, the distribution of network is becoming more wider and the structure of network is becoming more complicated. The devices and hosts of network are supplied by different manufacturers, which results in many kinds of systems and protocols exist in the network. The limits of persons for the network system maintenance work make daily maintenance difficult. So the management of network becomes very important. At present, the SNMP(simple network management protocol) is one protocol used widely and realized easily, which has been supported by many manufacturers and became the actual standardization protocol in the network management of the industry. The network management system in the paper is used to realize the management of topology, performance, fault of the FTTH network. In this paper, the market background of FTTH network, the model and conception of OAN (optical access network), the standard and function requirement of network management, and the actuality of FTTH network management are introduced at the first. After introducing the constitution, communication model, the management model and the solution of the FTTH access network, the paper provides the system analysis, summary design, detail design and realization of the FTTH network management system based on SNMP.更多还原
