| 中文简介 |
本课程的目的是介绍计算机网络的关键概念和原理。本课程将结合自顶向下和自下而上的方法来研究互联网及其协议栈。讲述的网络架构、协议和应用程序实例包括电子邮件、Web和媒体流。本课程将涵盖支持此类网络应用程序所需的通信服务（如TCP/IP）。本课程在讲述实际网络（包括有线和无线局域网环境）中实施和部署通信服务之后，讨论网络管理问题。在整个课程中，将以互联网的架构和协议为主要例子来说明计算机网络的基本原理。 |
| 英文简介 |
The aim of this course is to introduce key concepts and principles of computer networks. The course will use a combination of top-down and bottom-up approach to study the Internet and its protocol stack. Instances of architecture, protocol, application-examples will include email, web and media-streaming. We will cover communications services (e.g., TCP/IP) required to support such network applications. The implementation and deployment of communications services in practical networks: including wired and wireless LAN environments, will be followed by a discussion of issues of network-management. Throughout the course, the Internet’s architecture and protocols will be used as the primary examples to illustrate the fundamental principles of computer networking.
