摘要
组播是一种应用广泛的点到多点或多点到多点的通信方式。本文剖析了光层组播的特点,在综合分类的基础上,对光网络组播路由算法的最新研究进展进行了归纳和总结,指出了其面临的问题与挑战,并对今后需重点研究的方向进行了展望。
Multicast provides a means of point-to-multipoint or muhipoint-to-muhipoint communication, which has several applications. First, the character of optical muhicast was analyzed. Second, the newest advance of muhicast routing algorithm in optical networks based on the integrated classification was summarized. Finally, the corresponding problem and challenge were indicated, and the further direction which is critical to the problem was foreseen.
