图书介绍:人们运用ATM技术的根本目的是提供更加丰富多彩的宽带应用,而这些新应用的增长点主要来源于商业用户和居民宽带用户。本书从高层应用的角度出发,着重研究ATM技术如何向居民用户提供先进的宽带业务。ATM论坛的首任主席FredSammartino评价该书:“这是第一本全面反映居民宽带网络领域最新进展的专著......不仅如此,该书还深入剖析了基于ATM技术的端到端的业务结构,正是这种结构才使未来的交互式宽带应用走向实践。”本书共分三部分:第一部分主要从多媒体应用和因特网的需求出发讨论宽带业务的应用特征,包括应用分类、业务量需求和应用QoS描述等;第二部分介绍了ATM技术的基本原理和信今规范;第三部分详细描述了居民宽带网络的结构,包括基于xDSL的ATM技术以及HFC网与ATM相结合的新结构和新方法。本书既适合大专院校通信与计算机专业的研究生和高年级本科生作为参考书,也可供从事电信和计算机类的工程技术人员阅读。
