Abstract:

Multicast provides a means of point-to-multipoint or multipoint-to-multipoint communication,which has several applications.First,the character of optical multicast was analyzed.Second,the newest advance of multicast 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.

Key words: WDM, optical network, multicast, routing algorithm
