摘要： 当前使用的IP组播模型不提供接入控制,任何用户可以向组播地址发送数据,也可以任意加入组播组成为成员接收数据.在具体分析了组播参与者①的不同类型和对接入控制的不同要求后,引入了策略控制系统,提出了基于策略的组播接入控制,给出了该系统的模型,并具体阐述了用户接入时的请求、应答、配置ACL的过程.

关键词: 策略, 组播, 接入控制, ACL

Abstract: The current multicast model provides no access control mechanism.Any host can send data directly to a multicast address or join a multicast group to become a member.After analyzing the different types of multicast participants and the requirements of access control, a multicast access control system based on policy ACL is put forword.And after the model of this system is given, the process of requesting, replying and ACL configuration of the host access is also elucidated in this paper.

Key words: multicast, ACL, policy, access control
