This course is an in-depth study of data communications and networks. The course covers design of, and algorithms and protocols used in, the physical, data link, network, transport, and application layers in the Internet; methods for modeling and analyzing networks and an introduction to network security. Programming projects will be required.

This is a junior-level course; I will not mandate you to come to class (you are still responsible for all the material covered in class). The class projects are a major part of this course, and please be aware that you will be working in groups of two.

We will be using Mycourses as a course discussion/bulletin board. You are expected to check it at least once every few days, use it as the first place to ask questions, and answer others' questions. The professor will regularly monitor the board, and your participation will count towards your grade.

Below is a rough schedule for the lectures in CSCI-351. This is subject to change; please check back often. Acknowledgement: lecture slides are built with the help of Prof. Alan Mislove, Christo Wilson, and David Choffnes's class.
