异步转移模式ATM作为一种新的交换和复接体制，已经被国际电联ITU挑选为宽带综合业务数字网B—ISDN的核心技术。ATM技术的主要目的是使数据业务、视频业务、话音业务等能在统一的全数字网络中实现传输和交换，同时提供灵活简捷有效的动态资源分配。文章在说明通信业务各自千差万别特征的基础上，进行业务归类，并给出几种公平排队服务算法。
Asynchronous transfer mode ATM as a new exchange and multiplexing system has been selected by the ITU ITU as the core technology of broadband integrated services digital network B-ISDN. The main purpose of ATM technology is to enable data services, video services and voice services to be transmitted and exchanged in a unified all-digital network while providing flexible and efficient dynamic resource allocation. Based on the description of different features of each communication service, the article classifies the services and provides several algorithms for fair queuing services.
