An efficient mechanism for dynamic survivable multicast traffic grooming
We study sub-wavelength level protection for dynamic multicast traffic grooming. A lightpath-fragmentation based segment shared protection (LF-SSP) scheme is proposed. By properly splitting primary and backup lightpaths into segments, more efficient resource sharing for both traffic grooming and protection is achieved. Simulation results verify the good performance of the proposed algorithm. Effects of a few factors to algorithm performance have also been carefully evaluated.
