摘　　要：文章给出一种基于移动组的全序可靠多播协议-MGTOM(Mobile-group-based Totally Ordered Reliable Multicast)协议,借助于逻辑令牌环来实现。MGTOM协议实现了移动组多播的原子性和全序性,原子性用于保证多播消息能够最终传递到移动组内的所有移动Agent,全序性则保证任意一对多播消息都按照相同顺序被所有组内移动Agent传递。在多播算法中,为了保证原子性,所有收到多播消息的组成员必须回复,然后持有令牌的组成员作为Sequencer,对多播消息进行排序。In this paper, a mobile group-based totally ordered reliable multicast protocol, named MGTOM, is given, which is implemented by means of logical ring structure. M6TOM achieves atomicity and total ordering properties of mobile group multieast communications. The atomicity property ensures that multicast messages could finally be delivered by all group members while the total ordering property ensures that any pair of multicast messages could be delivered in same sequence by all group members. In multicast algorithm, in order to ensure the atomicity property, all group members which have received multicast messages should send replies while in to ensure the total ordering property, the group members who hold the token should sort the multicast messages.
