Computer Networks and Data Communications
This course describes the transport of multi-media information among distributed computer systems, emphasizing the "convergence" of real-time and non-real-time information transmission and processing. Concepts covered in some detail include: (i) the services that require secure, errorless, and very high-speed transmission of inter-related real-time and non-real-time information, e.g. Voice Over Internet Protocol (VoIP), Peer-to-Peer (P2P) sharing, Video on Demand (VOD); (ii) how computer network architects and designers enable these services by engineering computer networks (particularly the modern Internet) that meet these service requirements. In particular, the course emphasizes how modern communication protocols underlie modern computer network architecture and design.
At the end of the course, students will be able to:
Apply general design principles to the design of different types of computer networks (access, core, backbone).
Describe the basic functionality of the most important protocols in each protocol layer used in the Internet.
Explain, using network design principles and protocol layering techniques, how the Internet supports multi-media services, e.g. voice, video, and data integration.
Use a software-based protocol analyzer (packet sniffer) to examine the detailed workings of various Internet protocols.
