Abstract: Multicast is a special and high efficient communication mode in the computer network. In the multicast commumication mode, the senders/ sources send information to a group of selected receivers, mulitcast has the virtues of both unicast and broadcast, so, it plays a very important role in multipoint communication. In this paper, the mechanism and the characters of multicast are described. In addition,the implementation of multicast is illustrated concretely.
