The course will present data communications fundamentals and computer
networking methods, using the ISO 7-layer reference model to organize
the study. Attention will be focused on the protocols of the physical,
data link control, network, and transport layers, for local and wide
area networks. Emphasis will be given to the Internet Protocol Suite.
Some advanced topics, such as network security, wireless and mobile
computing networks, will also be covered. Students will program
simplified versions of the protocols as a part of the course project.

Homework assignments are on a semi-regular basis.
We will use a network simulator, Network Workbench (NW), for course
projects. This simulator enables the study and implementation of various
networking protocols in a "virtual reality", where network devices
(namely, routers and switches) are simulated and your protocol
implementations can be tested and debugged. The official platform is
site-unix (meaning that the TA will grade your projects on that
platform). Currently, it points to zeus.ite.gmu.edu. On site-unix, the current version of NW, nw42, can be found
at /usr/local/nw42. (Note that, for security reasons, you can
login into site-unix only from osf1.) To install nw42 in your home
directory, follow the instructions in
Alternatively, you can install NW on your PC from
netlab.gmu.edu/NW. Note that site-unix is the only official
platform. You are responsible for resolving any compatibility issues
before submitting (although we expect few such problems).
Your grade will be calcuated as follows:
- 5% Participation
- 15% Projects
- 20% Assignments
- 25% Midterm exam
- 35% Final exam
