dc.description.abstract在全光的WDM/DWDM網路中,為了能確保與滿足各種不同寬頻網路服務的需求,所以無論何種網路架構都必須提供良好的路徑保護切換(Protection Switch)與動態路由恢復(Dynamic Restoration)機制以避免網路不預期的發生故障(Failure)而造成大量的資料流失。故本論文將著重於討論光纖網路控制與故障管理技術的研究,對於在WDM/DWDM的網路架構下,提供良好的網路保護和恢復能力。因此,本論文研究將針於較複雜之WDM/DWDM-Based網狀網路使用1+1路徑保護方案(1+1 Path Protection Scheme)進行研究與探討;我們將提出兩種分配路徑方式與演算方法來分配尋找所需之主要路徑(Primary Path)與相對應的備用路徑(Backup Path) 。在模擬分析部分,我們將考慮備用路徑具互斥性(Link-Disjoint)與鏈結共享(Link-Shared)兩種方案進行討論。前者分配尋找備用路徑方式有較高的可靠度(Reliability),而後者之方式其路徑分配成功機率較高與有較好的網路使用效率。與當主要路徑發生故障時,計算切換到備用路徑的保護交換時間(Protection Switching Time)。最後我們將會依照網路的狀況去預測所能分配建立之路徑數目。zh_TW
dc.description.abstractAs various applications have been deployed in the internet flourishing, the network traffic has also grown quickly especially for the multi medium services, more network bandwidth and better quality are required rapidly. Therefore, the development of the network transport technologies are not only to increase the IP packets’ forwarding performance by using the hardware switching such as Asynchronous Transfer Mode (ATM) technology, recent researches are also devoted to forward the IP packets over the Dense Wavelength Division Multiplexing (DWDM) directly. These technologies have gradually moved the functions of IP layer, such as routing and route protection, down to lower layers (e.g. ATM, SDH/DWDM). However, the traditional methods used in the IP layer are no longer suitable for the use in the lower layers due to the lack of IP layer information in the lower layer and the layer violation. Then, the purpose of this project are to study the route allocation schemes under different IP over DWDM architectures and the route protection and restoration issues are also studied in according for the consideration of the network reliability.en_US
