摘　　要：提出了一个改进的稀疏分光器配置约束下的改进算法。在稀疏分光器配置约束下,多播路由不再是图论中"树"的形状,多播路由可能存在逻辑圈。现有的多播路由算法没有考虑这个特点,改进对此算法作了一下改进,通过仿真证明改进算法提高了网络性能。This paper presents an improved configuration of the sparse constrained by the improved algorithm. Spectrophotometer at sparse constrained configuration, multicast routing graph theory is no longer a ＂tree＂ shape, the existence of possible multicast routing logic circle. The existing multicast routing algorithms do not consider this characteristic to improve the look to improve on this algorithm, the simulation proved to improve the algorithm to improve network performance.
