Description
The goal of this course is to cover the introductory topics in networking. We will go through the standard protocols in each layer of the OSI stack and discuss design patterns commonly used in networking protocols. While part of the discussions will be on traditional protocols, one part of the course will focus on newer developments in the networking world. Specifically, we will discuss HTTP/2, Quic, MPTCP, data centers, and SDNs all in the context of the OSI stack.
Textbooks
I will teach the course top-down. There is no required textbook, but the recommended book is
Computer Networks, A Top Down Approach by Kurose and Ross [KR]
Prerequisites
Grading
(Tentative) There are several components in this class: Assignments, Projects, Exams, and Summaries. The grading criteria are as follows:
Midterm and Final exam: 40%
Project: 20%
Paper summaries: 4%
Assignments: 36% (12% each)
Project: The project is meant to be open-ended. Around 3 weeks into the semester, we will discuss possible project ideas. You should choose a project and submit a project proposal. Mid-way through the course, you will present a report on project progress. At the end, you will present your projects to the instructor and submit a project report.
I encourage students to do the project in groups of 2 or 3. If you want to do a project without any team members, come talk to me. The scope of the project is different if you have 1 versus 2 versus 3 team members. All project-related reports should be submitted before 9.00PM on the day they are due.
Paper summaries: There are 4 papers assigned for reading. For each paper, you are expected to provide a summary. More details on how to write a paper summary will be up on Piazza. Paper summaries should be submitted at 2.30PM on the day they are due (that is, just before class starts). No extensions are allowed. If you don't submit by the deadline, you forfeit the points.
For grading, I will choose the top 3 summaries.
Assignments: There will be 3 assignments in all. Assignments should be submitted before 9.00pm on the day they are due. The assignments are programming heavy. You can program in C or Python.
Submissions instructions and total attempts: We will use Blackboard for submissions. If you want to resubmit after you already submitted one version of your assignment/project/summaries, you may do so. But you are allowed a maximum of 2 resubmissions (i.e., a maximum of 3 attempts). Irrespective of anything else, your last attempt will be considered. This means, if you submit one version of your homework before the deadline and submit another version after the deadline, we will grade the later submission and grade you according to the late submission policy.
Grace period: You get a total 24 hours of grace period across your three assignments, starting from the first assignment deadline. So if you submit your first assignment 24 hours late, then you no longer have any grace period, but will not be penalized. If you submit your first assignment 12 hours late, you still have 12 hours of grace period left. Once your grace period is over, each assignment you submit late will be subject to the late penalty below. There is no grace period for summaries and projects.
After the submission deadline: If you submit your homework at hour h after your deadline (after your grace period), here are the grade penalties
- If 0 < h <= 5, 5% of your grade
- If 5 < h <=15 hours, 8% of your grade,
- If 15 < h <= 24, 15% of your grade
- If 24 < h <= 48, 30% of your grade
- If 48 < h <= 72, 40% of your grade
- If 72 < h <= 96, 60% of your grade,
- h > 96, you cannot submit the homework.
I should note here that I almost never give extensions on any submissions.

Deadlines: All deadlines are tentative in the beginning. The firm deadlines will be announced in class and posted on Piazza.
Discussion policy: All discussions will take place on Piazza. Please be respectful of your fellow classmates and your instructor when posting questions. If you post questions or comments on Piazza that I deem derogatory or otherwise not constructive, I will remove them.
You are expected to read your Piazza posts frequently. I will be posting important announcements on it.
Questions posted on Piazza can take up to 24 hours for a response from the instructor or the TA. If you ask a question very close to an assignment deadline, they may go unanswered.
Grading policy: I will not be able to give any individual student extra credit for additional work or projects. However, for projects that are especially good, I may award additional points. This is at my discretion.
Academic Dishonesty: I take academic dishonesty extremely seriously. Your assignments will be tested for plagiarism not only against your classmates but also with all past assignments. If I find evidence of dishonesty, I will immediately notify the Graduate Program Director and give you an F in the class.
