一代又一代的专业技术人员}RDouglas 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。本书是其中的第二卷，作者深入探讨了TCP/IP的设计方案，考察了每个协议的具体细节及实现技术，并惹重介绍了协议软件的内部机制。贯穿全书的是一个利用ANSI C构建的可运行系统，用来讲解协议之间的交互操作、完整的实现过程及内部结构。

本书是关于计算机网络的经典教材。全书共三卷。第二卷在第一卷介绍了TCP/IP基本概念的基础上，进一步详细讨论了TCP/IP的实现细节。这一卷的突出特点 非常注重实际。作者利用程序代码实现了TCP/IP的每个技术细节，并且所有代码在书中均可找到，有助于读者深入了解并掌握TCP/IP的细节内容。书中附录分别给出了过程调用交叉参考表、程序代码中用到的C数据结构交叉参考表及Xinu函数和常量。
