  • 摘要: 針對彈性光網絡中多鏈路故障100%保護的資源消耗冗余度較高的問題，該文提出一種最小故障風險損失的概率保護(MFRL-PP)策略，在多鏈路故障時為業(yè)務提供高效率的概率保護。在MFRL-PP策略中，該文設計了一個綜合考慮鏈路負載和故障風險的代價函數，為業(yè)務選擇故障風險小且頻譜資源消耗少的概率保護光路。當最小故障風險路徑無法傳輸時，為進一步降低概率保護光路的故障風險損失，該文還設計了一種非對稱業(yè)務流分流的最小故障風險損失概率保護機制，以便選擇故障風險損失最小的分流路徑組作為傳輸光路。同時，在傳輸光路的頻譜分配階段，提出了基于最大頻譜重合度的可用頻譜塊選擇策略，以減少頻譜碎片的產生。仿真結果表明所提策略不僅有效地提升了頻譜利用率，還較好地實現了帶寬阻塞率與故障風險的平衡。
    Abstract: Due to the high resource redundancy of full protection for requests multi-link failure in elastic optical networks, the strategy of Minimum Fault Risk Loss Probability Protection (MFRL-PP) is proposed to protect the request with high spectrum-efficiency. In the MFRL-PP, a link cost function integrated considering the link payload and fault risk is designed to choose the protection lightpath, which has minimum fault risk and consumes a small amount of spectrum resource. When the minimum fault risk lightpath is unavailable for shortage of idle spectrum resource, for further reducing the failure risk of the probability protection lightpath, a minimum fault risk loss probability protection mechanism for the non-symmetrical flow is designed to split the flow into two sub-flows for easily selecting the protection branch lightpath with the minimum fault risk loss. Moreover, in the phase of spectrum allocation for the lightpath, for reducing the number of spectrum fragmentations, a spectrum allocation strategy based on the maximum spectrum coincidence degree is put forward to allocate spectrum resource. The simulation results indicate that the proposed MFRL-PP algorithm can improve the spectrum utilization, and provide a better tradeoff between the bandwidth blocking probability and fault risk degree.
