【摘要】 自动交换光网络(ASON)技术相较于原有的光传送网技术,更加可靠、灵活、高效,可提供动态的网络配置,提高了网络效率和快速的网络保护恢复能力,支持不同业务等级的客户需求,能够进行网络资源自动发现,更好地适应IP业务传送,代表着当前光传送网络发展的新方向,近几年在各电信运营商得到了较大规模的应用。本文作者从事光通信网络工程的规划设计工作多年。本文结合光传送网现状,对ASON关键技术及其在传输网上的应用进行着重分析,提出了ASON当前的建设策略,并对临汾联通的ASON工程进行了方案设计论文主要的研究工作如下：(1)对ASON的网络结构体系、关键技术进行了阐述;(2)针对临汾城域传输网的发展需要和其目前存在的主要问题,提出了城域核心传输网智能光网络改造方案并对其进行分析、评估,对网络建设进行详细阐述；(3)对建设的华为OSN7500智能光网络进行业务加载测试,对业务QOS保证性能进行分析论证。更多还原

【Abstract】 Compared with the old optical transmision network, Automatically Switehed Optical Network(ASON) is more relibale, flexible and efficient.It can offer dynamic configuration for network.It improves the efficiency of network and the abaility of rapid protection and restoration, and it supports business needs of dieffernt levels of service, and it can automatically discover network resources and better meet IP transmission.ASON currently represents the new dieretion of optical transmission network development, the telecommunications operators will apply ASON on the network on a larger scale in recent years.The author works on the optieal communications network planing and desingning for many years. According to status of the current optical transmission network, this paper analysis The key to ASON technologies and ASON applications on the transmission network, gives the current building strategy of ASON, and completes the programme design of ASON works for Linfen United Network Communications Limited. This paper will offer better information and guidance of building of ASON.The main research is as follows:(1)It does a close traeing researeh on ASON key technologies and its application at home and abroad.(2)Through a thorough analysis and discussion on the need of Linfen local transmission network and its existing problems, the Paper gives a transmission network-building solution which is based on ASON technologies.It also brings forth a detailed program of the network construction.(3)The network test of HuaWei OSN 7500 is expounded, and the QOS of the network performance is reasoned in the Paper.更多还原
