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. Students will also program simplified applications
using socket programming in the course project.

Homework assignments are on a semi-regular basis.
We will have two types of projects. In the first type,
we will use a network simulator, Network Workbench (NW).
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 from osf1 if you cannot login directly.) 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).
The second type of project is socket programming based. You must be
familiar with socket programming in order to complete the project.
NOTE Assignments and Projects are individual efforts. We reserve the right to use MOSS to detect plagiarism. If your code does not compile, you get no credit.
Your grade will be calcuated as follows:
- 20% Projects
- 20% Assignments
- 25% Midterm exam
- 35% Final exam
