Course Description

This course will cover the basic principles of networking with a focus on protocols, implementations, and issues specific to the Internet. We will study how routing, transport, and internetworking protocols work using the Internet family of protocols as examples. A significant part of the course will focus on higher layer protocols and the application layer. We will selectively implement new protocols and network services; as such, this course will have rather a substantial programming component.

Final Project


Please keep up with and participate in the class forum. I will use the forum for broadcast announcements and to answer questions that may be interesting to more than one of you.  Further, the forum is the best medium for asking questions about homework, for debugging your programming environment, and for posting the latest Internet rumor.  Thus, unless it is private, post to the forum before writing e-mail.

Attendance, Group Interactions, and Class Participation

This is a senior-level course; I will not mandate you to come to class (you are still responsible for all the material covered in class).  The class project is a major part of this course, and please be aware that you will be working in groups of four. Lastly, note that 5% of your grade is based upon class participation.   This is to encourage you to voice your ideas in class and to post them to the forum.  Minimally, I must know your name by the end of the term in order for you to get any points for class participation.
