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: 18% (Proposal: 2%, Progress: 2%, final project report and presentation: 16%)
Paper summaries: 6%
Assignments: 36% (12% each)
Midterm and final exam: Midterm and final exam carry 20% each of your final grade. The final exam is not comprehensive. Both midterm and final exams are in-person and closed book but you can bring a cheat sheet. More details about the cheat sheet will be discussed in class.
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. If you are a Ph.D. student and want to do a project related to your research, do 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 8.30AM 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 will be 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.

Others
CSE 522: If you are registered for this class as CSE 522 (basic project), you will do exactly the same as anyone registered for CSE 534. The only change is that you will do the project in a single-person team.
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.
COVID changes: All classes will be recorded and uploaded to blackboard (however, I cannot gaurantee the quality of the recordings and I will not be able to re-record. So if there is a class where the recording doesnt work or if I forget switching my microphone on, then you are on your own). However, I expect everyone to attend class barring extenuating circumstances.
Masks: All students should wear masks in the class. The instructor will also wear masks at all time. If anyone does not wear a mask, I will have to ask you to leave
Laptop and devices: I have a no-laptop and no-device policy in class. Please put away your laptop and devices. I will accomodate students who have accessibility requirements or other needs, if send me email or come talk to me.
Statement regarding dealing with attendance and class schedule: Students are expected to report for examinations and submit major graded coursework as scheduled. If a student is unable to report for any exams or complete major graded coursework as scheduled due to extenuating circumstances, the student must contact the instructor as soon as possible. Students will be requested to provide documentation to support their absence and/or may be referred to the Student Support Team for assistance. Students will be provided reasonable accommodations for missed exams, assignments or projects due to significant illness, tragedy or other personal emergencies. In the instance of missed lectures the student is responsible to go over the slides from the previous lecture. The lecture will be recorded and posted but can be of varying quality.
