具体描述
本书是全球最具有权威性和经典性的计算机网络教材，我国各大专院校也广泛采用此书作为计算机网络课程的基本教材。作者Tanenbaum 教授以高深的理论造诣和丰富的实践经验，在书中对计算机网络的原理、结构、协议标准与应用等做了深入的分析与研究。
全书按照网络协议模型（物理层、数据链路层、介质访问控制子层、网络层、传输层和应用层），自底向上逐层讲述每一层所用的技术与协议标准，并给出大量实例。全书内容全面详实，体系清晰合理，叙述由简入繁、层层深入，自底向上方法也符合人类从底层到高层的认识规律，因此是公认的最适合网络入门的教材。
随着计算机网络的发展，本版对相关内容进行了大量修订、更新和补充，具体更新内容如下：
•无线网络（802.12和802.16）。
•智能手机使用的3G网络。
•RFID和传感器网络。
•使用CDNs进行内容分发。
•对等网络。
•实时媒体。
•网络电话。
•延迟容忍网络。
