| Abstract: | GMPLS is the core technology in the next generation networks. The purpose of the paper is to present an algorithm to solve the problem of getting shortest paths in GMPLS networks. And the algorithm combined with heuristic character is the constraint-based shortest path first algorithm with SRLG constraints. Furthermore, the simulation is made in order to verify the performance and validity of the algorithm. At the same time, the results of the simulation are also deeply analyzed. |
