Chapter 1 Computer Networks and the Internet
引言 Internet-connected “things”: laptops, tablets, smartphones → game consoles, surveillance systems, watches, eye glasses, thermostats, cars… What you will learn ? —— a broad overview of computer networking and the Internet. Introducing some basic terminology and concepts. Examining the basic hardware and software components. The network’s edge(网络边缘): end systems(端系统) and network applications(网络应用). The core of a computer network(网络核心): links(链路) and switches(交换机) —— transport...
Chapter 1 R&Q
Review Questions What is the difference between a host and an end system? List several different types of end systems. Is a Web server an end system? There is no difference. Throughout this text, the words “host” and “end system” are used interchangeably. End systems include PCs, workstations, Web servers, mail servers, PDAs(Personal Digital Assistants), Internet-connected game consoles, etc. Yes. The word protocol is often used to describe diplomatic relations. How does Wikipedia...

Chapter 2 Application Layer
In this chapter, we study the conceptual and implementation aspects of network applications. We begin by defining key application-layer concepts, including network services required by applications, clients and servers, processes, and transport-layer interfaces. We examine several network applications in detail, including the Web, e-mail, DNS, peer-to-peer (P2P) file distribution, and video streaming. We then cover network application development, over both TCP and UDP. In particular, we...
Lab Checkpoint 0 networking warmup
1 在你的计算机上安装 GNU/Linux CS144 的作业需要 GNU/Linux 操作系统和一个支持 C++ 2023 标准的最新 C++ 编译器。请选择以下三个选项之一： 推荐：安装 CS144 VirtualBox 虚拟机镜像（说明在 https://stanford.edu/class/cs144/vm_howto/vm-howto-image.html）。 使用我们课程的优惠券代码，使用 Google Cloud 虚拟机（说明在 https://stanford.edu/class/cs144/vm_howto）。 运行 Ubuntu 24.04 版本，然后安装所需的软件包：12sudo apt update && sudo apt install git cmake gdb build-essential clang \clang-tidy clang-format gcc-doc pkg-config glibc-doc tcpdump tshark “风险自负”地使用其他 GNU/Linux...
Chapter 4 The Network Layer (Data Plane)
The network layer can be decomposed into two interacting parts: the data plane The data plane functions of the network layer—the per-router functions in the network layer that determine how a datagram (that is, a network-layer packet) arriving on one of a router’s input links is forwarded to one of that router’s output links. the control plane The control plane functions of the network layer—the network-wide logic that controls how a datagram is routed among routers along an end-to-end path...
Chapter 3 Transport Layer
Transport layer provides communication services directly to the application processes running on different hosts. 3.1 Introduction and Transport-Layer Services logical communication A transport-layer protocol provides for logical communication between application processes running on different hosts. Application processes use the logical communication provided by the transport layer to send messages to each other, free from the worry of the details of the physical infrastructure used to...
