Computer Networks: A Systems Approach (5th edition), by Peterson and Davie, Morgan Kaufmann, 2011, Hardcover ISBN: 9780123850591, eBook ISBN: 9780123850607. Note that while the class has a textbook, we will not follow its order of presentation; instead, we will use the textbook as a reference when covering each topic. The primary learning resources for this class will be the lecture slides and practice problem sets posted on Brightspace.

40% grade — Programming Labs

Lab Description	Regular	Honors
Lab 1: HTTP Web Client	5%	5%
Lab 2: HTTP Web Server	15%	15%
Lab 3: Distributed Routing	10%	5%
Honors Milestone	–	5%
Lab 4: Reliable Transport	10%	10%

Lab 1 and Lab 2 will be in C while Lab 3 and Lab 4 will be in Python. All labs must be done individually with no collaboration and no use of AI tools allowed. No extensions will be granted for lab submissions as students will be given ample time to finish each lab.

60% grade — Exams
There will be 3 exams (2 midterms and 1 final) each carrying 20% credit. The syllabus for the exams will be non-cumulative, i.e., the syllabus for the next exam will not include topics covered in previous exams. All exams will be closed-book with no collaboration and no use of AI tools allowed. Barring extraordinary circumstances (serious medical situations or family emergencies, accompanied by verification and a prior notification to the instructor), no make-ups will be granted for exams.

Students who are most active and helpful in answering questions on Piazza may receive bonus points.

Policy for Late Submissions

If a lab is submitted within 24 hours (1 day) after the deadline — 25% grade penalty.
If a lab is submitted within 48 hours (2 days) after the deadline — 50% grade penalty.
No lab submissions will be accepted beyond 48 hours (2 days) after the deadline.

Policy for Re-grade Requests

Students may submit re-grade requests for labs within 48 hours (2 days) after the grades are released. All re-grade requests must be submitted on Piazza as a private post with the title "Re-grade request for Lab [X]" followed by a justification for the re-grade request (without a justification, the request will be ignored). Any emails sent to the TAs or the instructor about the re-grade requests will also be ignored.

Unless expressly allowed, students are expected to complete all exams and programming labs by themselves. No use of AI tools is allowed for completing the programming labs and exams. However, students are allowed to discuss general issues with other students (programming techniques, clearing up confusion about requirements, etc.). Students may discuss particular algorithmic issues on Piazza (but they must not post or copy code!). If there is any doubt, students should contact the instructor.

Course staff will be using software designed to catch plagiarism and use of AI tools in programming labs and copying on exams. A student is considered in violation of the academic honesty policy regardless of whether they are the one "copying" or the one "being copied from".

Academic integrity is one of the highest values that Purdue University holds. Individuals are encouraged to alert university officials to potential breaches of this value by either emailing integrity@purdue.edu or by calling 765-494-8778. While information may be submitted anonymously, the more information is submitted the greater the opportunity for the university to investigate the concern. More details are available on our course Brightspace under "University Policies and Statements".

Punishments for academic dishonesty are severe, including receiving a failing grade in the course or being expelled from the university. By departmental rules, all instances of cheating will be reported to the Dean of Students. On the first instance of cheating on a programming lab or exam, students involved will receive a 0; the second instance of cheating will result in a failing grade in the course.

Use of Copyrighted Materials. All course materials, including lecture slides, practice problem sets, programming labs, exams, and solutions are subject to Purdue's copyright policies. Students must not share, distribute, or post any material on an online web site without checking with the instructor.
