Novel Routing Algorithms for Hierarchical Architecture in ASON
The hierarchical routing infrastructure in Automatic Switched Optical Network (ASON) is researched. Three operational algorithms MLLR (Multi-Layer Least Loaded Routing Algorithm), MLCR (Multi-Layer Least Congestion Routing Algorithm) and MROB (Multi-Layer Routing Algorithm based on backtracking) are proposed. In these algorithms, the resource coordination and balancing of multi-domain and multilayer are considered based on the fixed alternate hierarchical routing. A platform named AHORSP (ASON based hierarchical optimal routing & signaling platform) supporting our routing optimization scheme is proposed and demonstrated. Based on the platform the average block probability can be reduced effectively with acceptable time performance by these algorithms.
