The 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.
