异步传输方式环形网络（ATMR）是一种采用时隙结构适于多种业务的高速存取网络，具有广泛的应用前景。本文详细地介绍了ATMR的基本概念、工作原理、网络结构、应用特点、信元格式、协议参考模式、存取单元的组成及信元存取控制模块。对ATMR的几项关键技术，即网络窗口控制、复位方案和优先权服务进行了研究和分析。
Asynchronous Transfer Mode Ring Network (ATMR) is a high-speed access network that uses slot structure for a variety of services and has a wide range of applications. In this paper, the basic concepts, working principle, network structure, application characteristics, cell format, protocol reference mode, access unit composition and cell access control module are introduced in detail. Several key technologies of ATMR, that is, network window control, reset scheme and priority service are studied and analyzed.
