隨著多媒體及網際網路應用之快速發展,網路頻寬之需求日益加大。分波多工能提供Gb/s甚至Tb/s之大量頻寬,使之成為未來骨幹網路之最佳選擇。也由於其所攜帶之大量頻寬,單一之光纜斷裂便可能造成大量的資料流失。這使得具存活力之網路設計成為一項很重要的設計議題。在最近的研究中,Su提出「桶狀鏈路表示法」及相對之保護路由演算法。其具有簡單及適用於分散式系統之優點。但在這個演算法中,工作路徑為固定式,使之成為最少備用資源問題之區域最佳解。
在本論文中,我們藉由動態之工作路徑選擇於單一鏈路錯誤之條件下提兩個動態保護路由演算法:DWPRA及CDWPRA演算法。模擬結果顯示動態工作路由演算法能有效降低所需之備用資源。另一方面,我們也發現備用資源之分享能力與通量數及網路搶樸之平均節點分枝度有關。通量數越大、平均之節點分枝度越高,其備用資源之分享能力越好。
With emerging multimedia and Internet applications, it is continuously thirsty for more network capacity. Wavelength-division multiplexing(WDM) networks, which provide the communication bandwidth at order of gigabits or terabits per seconds, had been the candidate of future backbone networks. With the large bandwidth, single fiber cut will induce huge data loss. It makes survivability became a critical issues. In recent research, Su had proposed a bucket-based link metrics and corresponding algorithm. It is simple and suited for distributed system. But in this approach, the working path is fixed. It is implemented as a local optimal solution of minimum spare capacity problem.

In this thesis, we propose two dynamic protection routing algorithm DWPRA and CDWPRA by choosing the working path dynamically where only single link failure is considered. And the simulation results show that the dynamic working path approach can reduce backup resources more efficiently. We also find the sharing capability is associated with the number of demands and the node degree of the network topology. More demands or higher node degree, the more sharing capability will be.
