说明：  本书是一本关于TCP/IP协议原理编程技术的教材，由两部分组成：第1部分系统地介绍了TCP/IP协议族的体系结构，并分别介绍了IP层、传输层和应用层中各种协议的具体原理和工作机制；第2部分介绍了基于socket编程接口的网络编程技术，重点讲述了客户端和服务器端编程应注意的问题、可用的模式和技术。 作为一本TCP/IP协议理论基础和编程技术的教材，本书既注重清晰地描述概念和理论，又做到了理论联系实际，能有效提高读者对TCP/IP的理解和网络开发能力。它可作为高等院校计算机、通信等专业的教学参考书，也可供从事相关开发工作和网络管理人员参考。
(This book is a book about TCP/IP protocol principles of programming technology, teaching materials, composed of two parts: Part 1 a systematic introduction to TCP/IP protocol suite architecture and introduced the IP layer, transport layer and application of layer in the various agreements specific principles and working mechanisms Part 2 describes the programming interface based on a network socket programming technology, focus on the client and server-side programming should pay attention to the problem, the available models and techniques. As a TCP/IP protocol theoretical foundation and programming techniques of teaching materials, this book not only focus on a clear description of concepts and theories, but also succeeded in linking theory with practice, can effectively improve the readers of TCP/IP network of understanding and development capabilities. It can be used as institutions of higher learning the computer, telecommunications and other professional teaching refer)
