【摘要】 随着全球范围内互联网的迅速普及,各种新兴的网络应用层出不穷,以IP类业务为主的数据业务量已经逐步取代传统的语音业务量,成为电信网的主流业务量。而电信网,也由传统的语音电话网络,过渡为以数据业务为中心的电信网。以突发性为主要特征的数据业务要求新一代的光传送网(OTN)具有动态带宽分配、业务流量调整、路由选择、网络故障保护与恢复等功能。可重构式光分插复用技术(ROADM)是近年来兴起的一种新型光网络节点技术,它在传统WDM网络节点技术OADM的基础上,通过一系列改进措施,使之具有灵活的光波长调度能力,是OTN技术在光域内理想的网络节点形式。本文研究的目的,旨在通过对ROADM在OTN中的应用方案的研究,在不同的ROADM原理之间对比研究,为不同的OTN网络环境,寻求最佳的网络节点形态。本文第一章对ROADM技术的产生背景进行分析,说明采用这种节点技术的必要性；第二章简要说明ROADM的应用环境,从WDM传送网向OTN传送网的演进；第三章介绍ROADM技术的原理和特点；第四章对比分析ROADM+OTN的网络形式相对于传统WDM网络的优势,对ROADM在OTN中的应用方案进行比较分析,在现有设备形式的基础上,提出复合型ROADM设备形态的构想；第五章介绍采用ROADM节点的OTN网络在开通期间的测试要点；第六章总结全文,并对ROADM技术未来的发展作出展望。更多还原

【Abstract】 With the global context, the rapid popularization of the Internet, an endless stream of emerging network applications, IP-class business-oriented data traffic has been gradually replacing traditional voice traffic into the mainstream of telecommunications network traffic. The telecommunications network, but also from traditional voice telephone network, the transition to data-centric telecommunications network business. With sudden as the main characteristics of the operational requirements of a new generation of optical transport network (OTN) with dynamic bandwidth allocation, business traffic shaping, routing, network failure protection and recovery capabilities.Reconfigurable Optical Add-Drop Multiplexing (ROADM) in recent years, the rise of a new type of optical network node technology, which in the traditional WDM network nodes based on the OADM technology, through a series of improvements, so that it has a flexible optical wavelength scheduling ability is OTN technology in the optical domain the ideal form of network nodes.The purpose of this study, designed for ROADM applications in the OTN in the study, in different ROADM principle of contrast between the studies, for different OTN network environment, finding the best form of network nodes. This first chapter of the ROADM technology, the background analysis shows the necessity of using this technology nodes; second chapter a brief description of ROADM application environments, from the WDM transmission network to the evolution of OTN transport network; third chapter describes the principle of ROADM technology, and characteristics; fourth chapter comparative analysis of ROADM+OTN form of a network as opposed to the traditional advantages of WDM networks, for ROADM applications in the OTN in a comparative analysis, in the form of existing equipment based on the proposed form of hybrid ROADM equipment vision; fifth chapter describes the test for Service Fulfillment in OTN network with ROADM nodes;sixth chapter summarizes the paper, and ROADM technology, the prospects for future development.更多还原
