内容简介：

本书是计算机网络方面的经典畅销教科书，凝聚了两位顶尖网络专家几十年的理论研究、实践经验和大量第一手资料，自出版以来已经成为网络课程主流教材，被哈佛大学、斯坦福大学、卡内基-梅隆大学、康奈尔大学、普林斯顿大学、威斯康星大学、普度大学、得克萨斯大学、芝加哥大学等众多名校采用。
　　第5版秉承了前4版的特点，通过丰富的、基于实例的指导，来帮助读者理解计算机网络及其构件。全书的重点在于“为什么这样设计网络”——不仅详细叙述当今网络系统的组成，而且还阐述关键技术和协议如何在实际应用中发挥作用，从而解决具体的问题。
　　本书与传统网络教材最大的不同在于，不是按照osi层次机械地介绍计算机网络，而是采用“系统方法”，将网络看成是交互式的复杂系统。每章开头都给出一些启发式的问题，引导学生或专业人员用新学到的知识来解决实际问题；同时，在每章的最后还会补充一些新的工具和资源，帮助读者巩固和加深所学知识，全面理解复杂网络及其应用的工作原理和工作方式。
