异步传输方式环形网络的结构与协议

Structure and Protocol of Asynchronous Transfer Mode Ring Network

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 adopting slotted structure and suiting for multi - service. It has wideranging applied foreground. The basic concept, work principle. network structure, applied characteristic. cell format, protocol reference model, composition of access unit, block of cell access control are introduced indetail by this paper. Several key ATMR technologies,that is, network window control, reset scheme andpriority service are researched and analysed.
