目 录内容简介
《通信网基本概念与主体结构》(英文版)(第2版)除对第1版内容进行了更新外，还广泛引入了网络协议分析仪分析各种协议的操作过程。《通信网基本概念与主体结构》内容大致分为三部分。第一部分为综述，由前两章组成。主要通过广泛应用的网络业务介绍网络的变革与发展；并通过网络提供的服务讨论网络协议的分层模型和不同层之间的交互作用。
第二部分以电话网、局域网、分组交换网这些基础网络为例，介绍网络体系结构的基本概念和低层协议的主要技术。这部分包含第3章至第7章，其中，第3章介绍数字传输技术的基础知识，内容有不同媒体信息的数字化描述、数字调制、编码、检错、纠错、信道特性及各种传输媒质特性等。第4章介绍电路交换网络中的几种复用和交换技术，重点是SONET。第5章讨论对等层协议，主要讨论数据链路层的ARQ差错控制协议，滑动窗机理，以及实用的PPP协议和HDLC协议。第6章首先详细讨论媒质访问控制技术，包括随机访问、预约访问、信道化访问，然后对以太网、令牌环、FDDI和无线局域网的基本知识和协议作了简要介绍。第7章讨论分组交换网，介绍了几种常用的路由算法，并对不同类型的流量管理机制作了较为深入的分析。
第三部分讨论TCP／IP和ATM这两种主体网络，并进一步阐明基本的网络概念如何体现在这两种主体网络之中。此外，对当前某些热点课题也作了必要介绍。这部分由5章组成，其中，第8章讨论TCP／IP网络的结构和相关协议，包括IP、IPv6、TCP、UDP、内部路由协议和组播路由协议等。第9章讨论ATM网络，主要介绍ATM层和ATM适配层，并对信令和PNNI路由选择作了基本介绍。第10章介绍现代网络结构中的基本概念和主要协议，包括综合服务、区分服务、互连模型以及RSVP、MPLS、RTTP、SCP等协议。第11章介绍网络安全协议和加密算法。第12章讨论网络中的多媒体技术和相关标准，包括数据压缩、信号编码以及分别用于图像和视频编码的JPEG、MPEG标准。
