书籍介绍
这不是一本适合一次性读完的书，而是一座可以反复进出的网络世界。全书自应用层向下逐层剖析，从HTTP、P2P、RIP这类读者熟悉的应用讲起，一直深入到传输层与网络层的协议机理，把'数据究竟如何在主机间流转'讲得清晰透彻。它的独特之处在于分层视角：应用层由开发者掌控，运输层则由系统接管，这种'边界感'帮助读者理解协议之间如何分工协作。书厚、第一章难读、翻译被诟病，是绕不开的真实评价；但它被多所高校选为指定教材，前五章构成扎实基础，后续章节可自由取舍。适合想系统建立网络体系、又愿意啃厚书的入门者。
AI导读
核心看点
- 采用自顶向下方法，从应用层切入，逻辑清晰易懂
- 涵盖TCP/IP协议栈，深入解析网络层与传输层机制
- 结合P2P等现代应用案例，理论联系实际，生动直观
读者共识
- 内容全面且讲解透彻，是公认的计算机网络经典教材
- 自顶向下结构友好，但部分章节如第一章略显晦涩
- 翻译质量争议较大，建议条件允许者直接阅读英文版
精彩摘录
- "因为排队时延随时间变化，所以分组n发送到路由器n的往返时延实际上比分组n+1发送到路由器n+1的往返时延更大。的确，我们在上述例子中观察到了这种现象：到路由器6的时延比到路由器7的时延大。"
- "Whereas a transport-layer protocol provides logical communication between processes running on different hosts, a network-layer protocol provides logical communication between hosts."
- "rip是被当作一个应用层进程（虽然它是一个能操作UNIX内核中的转发表的特殊进程)来实现的，所以它能在一个标准套接字上发送和接收报文，并且使用一个标准的运输层协议。RIP是一个运行在UDP上的应用层协议。"
- "The application developer has control of everything on the application-layer side of the socket but has little control of the transport-layer side of the socket."
- "Many of today’s most popular and traffic-intensive applications are based on P2P architectures. These applications include file sharing (e.g., BitTorrent), peer-assisted download acceleration (e.g., Xunlei), Internet Telephony (e.g., Skype), and IPTV (e.g.,Kankan and PPstream)."
- "One interesting property of MAC addresses is that no two adapters have the same address. This might seem surprising given that adapters are manufactured in many countries by many companies. How does a company manufacturing adapters in China make sure that it is using different addresses from a compa"
- "EstimatedRTT = (1-α) · EstimatedRTT + α · SampleRTT"
- "Until the early 1990s the Internet was used primarily by researchers, academics, and university students to log in to remote hosts, to transfer files from local hosts to remote hosts and vice versa, to receive and send news, and to receive and send electronic mail. Although these applications were(a"

太厚了，比背笔记还沉，这科目听课挺涨知识，考试太恐怖。
很适合入门，难度小，当然第一章并不好读。有《Operating systems:three easy pieces》的那种亲切，并且同样会指出很多延伸阅读资料。虽然八百多页的厚度，但是仅前五章是基础内容，剩下的可以比较随意地取舍。非常好的书。
和第四版差不多，主要是更新……题目顺序和第四版打乱了😂
书是好书，就是期末让我一个星期学完这大砖头太残酷了！
好书，高校课本教材，大而全的优秀作品。
