Abstract
A matrix M is used to determine groups of potential regenerator placements and obtain potential end-to-end optical paths by selecting desired sequences of regenerators. Then, a hierarchical guided search may be employed to efficiently select desired N-tuple disjoint optical paths from the potential optical paths. The hierarchical guided search may employ a search graph and a search tree to guide the search and to eliminate candidate nodes and optical paths early in the search process.
