摘要： ＡＴＭ多点到多点连接存在数据信元穿插的问题。提出了一种基于令牌的协议。该协议能够协调各结点对多点连接的访问以避免数据信元穿插，并有一套公平保障和优先级机制，充分保证各结点对多点连接使用的机会均等和紧急数据能得到及时地发送。另外，该协议还有易于扩充结点、扩展容量以及易于在现有ＡＴＭ网络设施上实现等优点。

Abstract: Multipoint-to-multipoint connection (multipoint connection) is one of the best solutions to multipoint communication over ATM networks. In this paper, a protocol based on token is proposed. which can prevent data cells from different sources in the multipoint connection from interieaving. The protocol can control access of nodes to the multipoint connection with no any additional equipment. A fairness and priority mechanism is also provided to ensure the fair and urgent access of nodes tp multipoint connection. Moreover, this protocol makes multipoint communication easy to add or drop nodes, to extend capacity and easy to be carried out in existing ATM networks infrastructure.
