For abundant bandwidth, all-optical mesh networks have been more and more important in communications, and multicasting is one of the key technologies to that. The problem to find a minimum multicasting tree is NP-hard, and all the existing algorithms are heuristics. Most of them are based on the idea of being greed. A greedy idea is always shortsighted. While it could get a good local effect, it...
The constructing of multicast light-trees in WDM network with sparse splitting has been proven to be an NP-complete problem. The Member-Only (MO) algorithm provides the best links stress and wavelength usage, and the Distance Priority (DP) algorithm reduces the diameter of tree and average delay, which are sensitive in multicast applications. In order to diminish the diameter of tree and average delay...
