| 中文摘要 | A fast protection scheme with low redundancy is needed for single link failures in wavelength-division multiplexing (WDM) optical networks. This paper analyzes the restriction of perfect pre-configured protection on pre-configured structures and then theoretically compares the protection offered by the pre-configured protection cycle (p-cycle) and that of the pre-configured protection path (p-path). A hybrid fast protection scheme was then developed which mixes the p-path and p-cycle. This scheme selects p-cycles and p-paths in various proportions as pre-configured structures for near optimal configurations by solving an integer linear programming (ILP) problem. Simulation results with the COST 239 topology show that this hybrid protection scheme provides 10% better in network redundancy than a pure p-cycle scheme. Meanwhile, it retains the merits of the p-cycle for fast protection. |
