Allocation of Spare Capacity for Shared Protection of Optical Paths in Transport Networks
ReferenceProceedings of the Third International Workshop on Design of Reliable Communication Networks (DRCN'01), Oct. 2001.
AbstractThe planning of capacity for shared protection is investigated. After recapitulation of the different protection schemes, the similarities between wavelength-allocation for light-paths and the sharing of network resources for protection is discussed. The concept of a protection sharing group (PSG) is introduced and an efficient algorithm to form PSG is presented. A heuristic approach to route the paths of a PSG is discussed. Using case studies for rings and a Pan-European network, the performance of the presented algorithms is evaluated.
