Course OverviewThis course introduces students to the basic principles of computer networks. Although current technologies will be discussed, the emphasis is on understanding the important concepts in modern computer networks and issues that affect design and implementation. The programming assignments require a good background in programming in C or C++ and will involve UNIX system calls. Some of the material covered in CS 2303 (systems programming concepts) will be assumed. Knowledge of some material in CS 3013 (operating systems) shall also be helpful.

Academic Honesty: Cheating or plagiarism will not be tolerated and will result in an NR grade for the course. Discussing assignments and approaches to solving them is permitted, but the expectation is that programs turned in are work of that programming team. It is fine to find algorithms or code from publicly available sources such as a textbook or a public website. However, you must document the source clearly in your code and in your program documentation. Failure to do this will be treated as plagiarism.
Class Websites: The class website is at http://www.cs.wpi.edu/~emmanuel/courses/cs4514/C07/. A myWPI class website has also been set up. The discussion board should be used for asking questions to avoid excessive emails and so that everyone can benefit from answers given. Emails should be used only for specific questions which are unique to you.
Class email: You have automatically been added to the class email list: firstname.lastname@example.org. The TAs and I will use this mailing list to send information to the class. Since everyone receives email sent to this alias, judicious and courteous use of this alias is expected. Inquiries which are specific to the TA/SA should be sent to email@example.com. The TA/SA will answer most of your questions regarding the programming assignments. I will answer questions about understanding concepts, policy issues or when the TAs are unable to answer your questions.
- Reading is mandatory, working ahead is encouraged.
- Exams are based on lectures, readings and assignments so class attendance is strongly encouraged.
Grade Policy: 40% exams (2 exams), 45% programming assignments (3), and 15% written homeworks (3)
http://www.cs.wpi.edu/Help/documentation-standard.html specifies the CS Department Documentation standards. Please follow these guidelines in all your documentation. Every function or subroutine must include the author of the function. This is critical to grading team projects.
All assignments should be submitted using the turnin facility (For more info on turnin, see http://www.cs.wpi.edu/Help/turnin.html). Please include a README file with each assignment to provide information to assist the TAs in grading your programs.
All programs turned in must compile and execute on one of the WPI Unix platforms. You are encouraged to develop your programs on WPI Unix machines because historically students have had difficulties porting their programs from other operating systems and because you may be given test files that work only on the CCC machines. Turned in programs that do not compile will not be graded and will receive a grade of 0. Points will also be deducted for programs without comments.
Late Assignment CreditLate programming assignments (turned in after the start of class on the due date) will be penalized 15 percent per day. Assignments will not be accepted after the start of class on the Friday following the due date. Since solutions to written homeworks will be handed out on the due date, written homeworks will not be accepted after the due date.
