Abstract

The routing technology is one of the key technologies in Automatic Switched Optical Networks (ASON). In this paper, we proposed a hierarchical approach for the dynamic establishment of constraint-based ligbtpaths in an ASON network. The algorithm performs multi-constraint path calculation on a transformed graph of interconnected border routers to find a feasible route based on the global state information present in each border router. We presented simulation results that have shown that the suggested scheme is capable of satisfying the requested with acceptable blocking probability at different traffic loads.
