摘　　要：近年来,随着网络技术的发展,使得各种单一媒体相继成为网络传输中的数据,进而各种媒体的融合使得网络多媒体运用层出不穷。而传统网络最初是为数据传输而设计的,是典型的点对点通信模式,是为保证数据可靠传输而设计的,所用的传输协议多为点到点的协议,其所具有的特点将增加网络发送负载,带来网络延时,这就带来了带宽的急剧消耗和网络拥挤问题。组播技术被认为是WWW技术推广之后出现的最激动人心的网络技术之一。组播技术应用在一对多通讯情况下,能够有效的降低网络流量,提高网络通讯效率,减轻服务器负荷,并能改善传送数据的质量。With the development of the Internet technology in recent years,many single media have been turned into data in Internet transmission gradually and the combination of different Internet media has emerged in endlessly.However,the traditional network,which is typically in point-to-point pattern,was originally designed to transmit data reliably by Peer-Peer Protocol(PPP).This characteristic of the traditional network increases network-transmitting load and leads to network delay,which in turn bring about such problems as the rapid consumption of bandwidth and network jam.Multicasting technology is regarded as one of the most innovative technologies after the popularization of WWW.Under the circumstances of one-to-more communication,multicasting technology can reduce network flux effectively,increase the efficiency of network communication,abate the load of the Internet servers,and improve the quality of data transmitting.
