内容简介
《TCP/IP详解》是已故网络专家、著名技术作家W. Richard Stevens的传世之作，内容详尽且极具专业，被誉为TCP/IP领域的不朽名著。
《TCP/IP详解·卷1：协议（英文版第2版）》是《TCP/IP详解》的第1卷，主要讲述TCP/IP协议，结合大量实例讲述TCP/IP协议族的定义原因，以及在各种不同的操作系统中的应用及工作方式。第2版在保留Stevens卓越的知识体系和写作风格的基础上，新加入的作者Kevin R. Fall结合其作为TCP/IP协议研究领域领导者的尖端经验来更新本书，反映了全新的协议和很好的实践方法。首先，他介绍了TCP/IP的核心目标和体系结构概念，展示了它们如何能连接不同的网络和支持多个服务同时运行。接着，他详细解释了IPv4和IPv6网络中的互联网地址。然后，他采用自底向上的方式来介绍TCP/IP的结构和功能：从链路层协议（如Ethernet和Wi-Fi），经网络层、传输层到应用层。
书中依次全面介绍了ARP、DHCP、NAT、防火墙、ICMPv4/ICMPv6、广播、多播、UDP、DNS等，并详细介绍了可靠传输和TCP，包括连接管理、超时、重传、交互式数据流和拥塞控制。此外，还介绍了安全和加密的基础知识，阐述了当前用于保护安全和隐私的重要协议，包括EAP、IPsec、TLS、DNSSEC和DKIM。
本书适合任何希望理解TCP/IP协议如何实现的人阅读，更是TCP/IP领域研究人员和开发人员的专业参考书。无论你是初学者还是功底深厚的网络领域高手，本书都是案头必备，将帮助你更深入和直观地理解整个协议族，构建更好的应用和运行更可靠、更高效的网络。
本书特色：
·W. Richard Stevens传奇般的TCP/IP指南，现在被顶端网络专家Kevin R. Fall更新，反映了新一代的基于TCP/IP的网络技术。
·展示每种协议的实际工作原理，并解释其来龙去脉。
