教学目标 Course Objectives

课程以互联网为载体，介绍现代计算机网络的基本概念和原理，重点介绍协议、架构和实现问题。课程首先介绍如何基于

已有的网络协议和架构来实现网络应用程序（如电子邮件、FTP）。接下来按照自顶向下的方式介绍网络协议的架构及各

层协议：应用程序、传输、网络、数据链路和物理层，以及层次化背后的原理及具体应用。课程的高级主题中探讨了包括

软件定义的网络、无线网络在内的多方面前沿技术。

Using the Internet as a vehicle, this course introduces the underlying concepts and principles of modern computer

networks, with emphasis on protocols, architectures, and implementation issues. Students will first learn how to

implement network applications (e.g., e-mail, ftp) using the existing network protocols and architectures. Students then

study how/why these protocols and architectures work by using the layered organization of the Internet in a top-down

fashion: Application, Transport, Network, Data Link and Physical layers. The course will also cover advance topics

including software-defined networking, wireless networking.

16.

预达学习成果 Learning Outcomes

成功完成本课程后，学生将获得以下技能：

1.熟悉层次化的网络通信架构（OSI 和 TCP/IP）。

2.了解客户端/服务器模型和有代表性的应用层协议。

3.学习 sockets 编程以及如何实现客户机/服务器程序。

4.了解可靠数据传输的概念以及 TCP 如何实现可靠性传输。

5.了解拥塞控制的原则和公平高效的权衡考虑因素。

6.学习路由算法和 IP 协议的语义和语法。

7.了解错误检测的基本知识，包括奇偶校验、校验和以及 CRC 方式。

As a result of successfully completing this course, students will:

1. Become familiar with layered communication architectures (OSI and TCP/IP).

2. Understand the client/server model and key application layer protocols.

3. Learn sockets programming and how to implement client/server programs.

4. Understand the concepts of reliable data transfer and how TCP implements these concepts.

5. Know the principles of congestion control and trade-offs in fairness and efficiency.

6. Learn the principles of routing and the semantics and syntax of IP.

7. Understand the basics of error detection including parity, checksums, and CRC.
