Abstract
Development of multimedia services on the Internet invites people's more and more attention to multicast technology. This paper analyses Internet Group Multicast Protocol and Controlled Multicast Protocol (CMP). Authentication and MD5 digest are used in CMP to provide a multicast router the ability of control. The paper gives one way to implement CMP in the service of Internet TV of 3Tnet Broadband Information Network. Furthermore the paper gives some idea to improve CMP so that it can be extended to adapt different multimedia services.
