Course Objective:
After you complete this course, you should be able to: list all layers and their functionality of the ISO and Internet network architectures; describe the concepts underlying the design and implementation of the major protocols at various layers; setting up local area networks; design, code, and evaluate retransmission protocols; and more easily learn network protocols, applications, and systems independently.
Prerequisites by topics:
No prerequisite courses. However, please consult the instructor if you are not sure about the programming requirement.

Submitting Work:
You should submit your work through the CourseSite course website. Your submission should be plain text (ASCII), PDF, or a Microsoft Word file. Any other format will not be accepted, unless you arrange for an exception ahead of time due to special circumstances.
Homework assignments will be graded primarily for completeness and correctness.
Homework is due on every Monday at 23:55 (i.e. 11:55 PM). No late hand-in homework will be accepted. Exceptions will only be granted if an extenuating circumstance can be proven to the instructor's satisfaction.
Collaboration / Academic Honesty:
All graded work is expected to be your own, unless the instructor has authorized collaboration in writing. In particular, you are not allowed to ask anyone but the instructor for help with your homework or programming assignments. However, you are free to discuss the topics and concepts of the course with your classmates, as long as you do not discuss the specifics of any assignment. Any violation of this policy could result in failure of the course.

Please visit the following two websites and read all details of the academic integrity policy: Academic Integrity at Lehigh University: http://www.lehigh.edu/~indost/integrity.html and Improper Collaboration Policy: http://www.lehigh.edu/~ejk0/cheating.html. Another website about Ante-Plagiarism.
