A survivable connection usually requires computing link-disjoint primary and backup paths. Finding a min-sum pair of link-disjoint paths whose total cost is minimized can be solved in polynomial time. However, adding extra requirements may render the problem NP-complete. In this paper, we study different variants of the min-sum link-disjoint paths problem. We examine the complexity of these problem variants and provide exact and heuristic algorithms for them.
