CS536: Data Communication And Computer Networks (Fall 2020)

CS536 is the graduate-level course in Computer Networks at the Dept. of Computer Science at Purdue University. In this course, we will learn how to build Internet and go through main network protocols used by one of the largest and critical cyber infrastcture (Internet), which is used by almost everyone everyday. We will also use the Internet protocol suites to understand networking principles and why we built Internet this way and how to innovate next-generation Internet.

What's New

This fall, CS536 offers a hybrid teaching mode which mixes online and classroom experiences. Some of you must learn online (online experience enrollment or distant learning), and some of you are allowed to go to the classroom (following the unverisity's guidance regarding COVID-19.)

Grading Policy

Course Policy

You need to obey course polices for all the courses in the department of Computer Science, Purdue. Here, I higlhight some important ones.

What is New about COVID-19?

More can be found at Fall 2020 Resources.

No late submissions are accepted for credits!

All assignments are due on the dates and times specified. It is the responsibility of the students to manage their time so that the assignments can be submitted on time. NO late submissions will be accepted for credits except for a documented severe medical or family emergency (specified below).

Assignment Regrades

If you feel that you have been unfairly graded on a lab assignment, homework or exam, you should petition the appropriate TA or Professor in writing within two weeks of distribution of the graded work. After two weeks, NO regrade requests will be honored. For lab assignments, you are allowed to change a few lines of code if that makes your program work, but there will be a penalty per change.

No makeup Exams

No makeup exams will be given except for a documented severe medical or family emergency.

Academic Dishonesty

We wish to foster an open and collegial class environment. At the same time, we are vigorously opposed to academic dishonesty because it seriously detracts from the education of honest students. Because of this, we have the following standard policy on academic honesty, consistent with Purdue University's official policy and Purdue's Honor Pledge.

It is permissible to discuss a GENERAL METHOD of solution with other students, or to make use of high-level reference materials in the library or online. If you do this, you will be expected to CLEARLY DISCLOSE with whom you discussed the method of solution, or to cite the references used. Failure to do so will be considered cheating or plagiarism. The use of “method of solution” means a GENERAL discussion of technique or algorithm, such as one would reasonably expect to occur standing in front of a whiteboard, and precludes the detailed discussion of code or written assignments.

Specifically, looking at another student's code on his/her computer monitor or copying code from an online source is NOT allowed.

Unless otherwise explicitly specified, all written assignments or code that is submitted is to be ENTIRELY the student's own work. Using any code or copying any assignment from others or from an online source is strictly prohibited without advance prior permission from the instructor. This includes but not limited to the use of code others have submitted in the past, or solutions found on the Internet.

All students work is their own. Students who do share their work with others are as responsible for academic dishonesty as the student receiving the material. Students are not to show work to other students, in the class or outside. Students are responsible for the security of their work and should ensure that printed copies are not left in accessible places, and that filedirectory permissions are set to be unreadable/ to others (e.g. use “chmod -R 700 *” from your home directory. If you need assistance protecting your work, please contact your TAs.

Students who encourage others to cheat or plagiarize, or students who are aware of plagiarism or cheating and do not report it are also participating in academically dishonest behavior.

Be aware that we will use a software tool called MOSS(http:theory.stanford.edu aikenmoss/) to check for copying among submitted assignments. Additionally, the instructor and TA will be inspecting all submitted material to ensure honesty.

Any case of academic dishonesty will be dealt with by a severe grade penalty in the overall class grade and referral to the office of the Dean of Students.

Emergency Policy

In the event of a major campus emergency, course requirements, deadlines and grading percentages are subject to changes that may be necessitated by a revised semester calendar or other circumstances. Any changes will be posted to the course web page or on Piazza. Information about emergency preparedness can be found <a href=“http:www.purdue.eduehpsemergency_preparedness”>here<a>.

If you unfortunately experience a medical or any other form of emergency, please do contact your instructor as soon as possible (usually no later than 3 days within its occurance).


You can also review the policies page maintained by Professor Gene Spafford for additional information about academic honesty and other policies.


If you are experiencing stress or personal problems, Purdue provides counseling services through the Purdue CAPS Center. Please see CAPS for more details.
