摘　　要：针对目前IP组播中,对于组播组成员缺乏有效控制的情况,提出了一种基于客户机/服务器模型的IP组播数据传输机制。服务器负责审核组播组成员身份的合法性,并保存通过认证的成员列表;客户机用于实现组播数据的发送和接收,为了保证数据的安全性,在发送和接收数据前需要向服务器进行必要的验证。客户机与服务器之间采用请求/响应方式,利用TCP协议进行通信。根据这种新的IP组播传输模型,重新设计了组播数据的接收和发送过程。Presently, it is ineffective to control the multicast member in IP Multicast, so a way of IP Multicast transmission based on Client/Server model are provied. The Server take charge of checking the IP multicast members＇ identification, and saving the legitimate member list; In client part, the sending and receiving multicast data are achieved. In order to ensure the security of data, it is essential to check the client＇s identification to server. The communication in Client and Server is using request/response way and TCP/IP protocol. According to this new IP multicast model, the sending and receiving process of multicast data are re-designed.
