| 摘 要： | 研究了波分复用(WDM)网状网中动态多播业务量疏导,提出一种新的辅助疏导模型,其可以描述当前网络资源状况和节点分光特点,并动态更新.进而提出一种有效的多播业务量疏导启发式算法(MGA),将业务的多播选路和波长分配同时完成.仿真表明,该算法在波长连续性限制、网络波长和节点收发器数目有限的情况下,具有较低网络阻塞率.

| Abstract: | This paper studies the dynamic multicast traffic grooming problem and proposes a novel auxiliary grooming model.The layered graph model can represent current network resource states and is modified adaptively.On this grooming graph model,multicast routing and wavelength assignment can be realized at the same time.We propose a multicast traffic grooming algorithm(MGA),and the simulations show it has lower network blocking probability under the constraints of wavelength continuity and limited wavelength and transceiver resources. |

| Keywords: | wavelength division multiplexing(WDM) multicast routing traffic grooming auxiliary grooming model |
