课程内容简介(Course Contents Introduction):

This course covers the basic concepts and principles of computer communication networks, where the main focus is the Internet. The network architecture is discussed in detail based on the layered reference model of the Internet, including the application layer, transport layer, network layer, and link layer. Moreover, this course covers advanced topics of networking, including wireless and mobile networks, multimedia networking, security in computer networks and network management. Particularly, a detailed explanation of popular Internet applications such as Web and P2P, transport protocols such as TCP and UDP, network layer protocol such as Internet Protocol, wireless local area network protocol such as 802.11, cellular Internet access mechanisms, multimedia networking protocols, computer network security issues such as authentication, integrity, key distribution, will be given, and the insight into their working principles will also be presented. Further, the instructor will teach the basic skills of doing research, including literature survey, problem formulation, and paper presentation.
