摘要： 针对当前低速组播业务请求与光网络高速波长传输容量的问题，基于光网络组播业务疏导模型，提出动态组播业务疏导算法，将新的组播业务请求疏导到已建立的光组播树上，达到提高网络资源的利用率、降低组播业务连接阻塞概率的目的。仿真结果表明，该算法可有效地改善网络性能。

Abstract: Aiming at the problem of the huge bandwidth gap between low capacity requirement of an individual multicast connection and high capacity offered by a wavelength channel in current optical networks, a multicast traffic grooming algorithm based on the multicast traffic grooming model is proposed by grooming new multicast traffic onto the optical multicast trees which have been built, in order to improve network resource utilization efficiency and reduce multicast traffic blocking probability. Simulation results show that the network performance can be improved significantly by the algorithm.

Key words: optical Mesh networks, Wavelength Division Multiplexing(WDM), multicast, traffic grooming
