Pre-configured protection cycles (p-cycles) have drawn many attentions due to the fully pre-connected cyclic structures, ring-like speed, mesh-like spare capacity efficiencies and fast switching characteristics. In this paper, we propose a novel removal of loop back (RLB) approach with standard protocol extension (the flooding based distributed cycle pre-configuration (F-DCPC)) to solve the resource...
The hierarchical routing and wavelength assignment problem in Automatic Switched Optical Network (ASON) is researched. Based on our analysis, three adaptive algorithms called MLLR (Multi-Layer Least Loaded Routing Algorithm), WMLCR (Wavelength-graph-based Multi-Layer Least Congestion Routing Algorithm) and BMR (Backtracking-based Multi-Layer Routing Algorithm) are proposed. A platform named AHORSP...
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...
