一代又一代的专业技术人员把Douglas Comer的《用TCP/IP进行网际互连》视为了解那些使因特网得以运转的协议和技术的敲门砖，它思路清晰，简单易懂。本书是其中的第三卷，作者讲解了应用程序软件如何利用TCP/IP在因特网上通信，并且这一版对全书内容进行了重新组织和全面更新。书中解释了客户一服务器范例及应用程序用于网络通信的套接字API，讨论了如何使用基本工具来创建服务器，并重点强调了实际的设计过程和技术，这些概念对于编程人员都是非常重要的。

本书是关于计算机网络的经典教材，是目前美国大多数大学所开设的计算机网络课程的主要参考书。目前国内外能见到的各种关于TCP/IP的书籍，其主要内容都参考了本书。本书的特点是强调原理，概念准确，深入浅出，内容丰富新颖。全书共分为三卷。第三卷主要讨论应用软件如何使用TCP/IP，重点研究了客户-服务器范例，并考察了分布式程序中的客户和服务器，举例说明了各种设计，讨论了应用网关和隧道技术。
