| Abstract(in English) | When an end-to-end wavelength path is established, a primary/backup redundant route pair for the path should be prepared in order to assure the reliability. In addition, an SRLG (Shared Risk Link Group), such as a cable or a disaster-expected area, -disjoint route pair is required, between its primary and backup route. This paper shows a method that can produce k SRLG-disjoint redundant route pairs between a specified start node and an end node by applying k-SPF (Shortest Path First) algorithm. Moreover, this proposed method is evaluated by applying the method to a network with links that have the same SRLG IDs because they are accommodated in the nodes located in a disaster-expected area. |
