邁入二十一世紀,人類生活方式多元化,資訊交換的需求更多,因此通訊網路的發展將是非常重要的課題。為了提供顧客又好、又快的多媒體(包括語音數據與影 )服 ,以高密度分波多工(Dense Wavelength Division Multiplexing )技術為骨幹的傳輸架構,將是建立都會光纖網路的最佳選擇。 本論文主要在研究都會光纖網路系統的規劃設計與應用。首先探討如何降低多重服務供應平台(Multi-Service Provisioning Platform;MSPP)及 DWDM所構成的光纖網路的建設及維運成本。使用都會型網路規劃模擬分析軟體(MetroWAND)將固網電信公司使用中的網路拓樸(命為Ring-TP)與另外我提出的兩種網路拓樸(命為Mesp-TP1和Mesp-TP2),就其頻寬使用率、網路建構成本、網路生存性和擴展升級等四項作比較分析。 希望本論文的研究成果,對未來都會光纖網路的規劃設計與部署 能有所助益。 Stepping into the 21 centuries,the human life becomes multi-styles,there are more needs for information exchanges than before,so one of the most important subject is the development of communication networks to satisfy the requirements of human life。In order to provide customs with a high speed and high quality multi-media (including voice,data and images) service,the transmission structure via the backbone of the Dense Wavelength Division Multiplexing (DWDM) technique has been recognized asthe best choice to construct the Metropolitan optical networks。 Main research in this thesis is the planning design and applications of the Metropolitan optical network system。At first we discuss how to reduce the investment and maintainence cost for the optical network with MultiService Provisioning Platform (MSPP) and DWDM。Then,by using the application software of MetroWAND,we analyze the bandwidth utilization,network construction cost,network survival and expand upgrade,etc,by considering three network topologies。The first one is the Ring-TP which is used in the fixed network telecommunication company now,and the two are the Mesp_TP2 and Mesp-TP1 that are enhanced from the previous one to consider the effective capacity。 We hope that the study results of this thesis can be helpful for the planning design and deployment of the Metropolitan optical network in the future。
