Course Description: The fundamentals of data communication networks. One goal is to give
some insight into the rationale of why networks are structured the way they are today and to
understand the issues facing the designers of next-generation data networks. Much of the
course focuses on various networks and their performance. Students are expected to have a
strong mathematical background and an understanding of probability theory. Topics discussed
include: layered network architecture, Link Layer protocols, high-speed packet switching,
queueing theory, Local Area Networks, and Wide Area Networking issues, including routing and
flow control and Wireless Communication.
