Provides students with an introduction to research in the fields of computer networking and distributed systems. Explores recent research advances in these fields, covers several sub-areas of specialty and ongoing research in them, gives students practice on how to read and analyze scientific literature in different sub-areas, and provides mentoring and guidance on how to conduct novel research in these fields. Also provides students with an overview of how research is conducted, from systems building to measurement and analysis, and from writing research papers to writing academic research proposals.
The class will once per week for a 100-minute session.
By the end of this course, I expect you to:
As this course is closest to a seminar course, the structure will consist of three components:
Lectures providing an overview of topics For the first meeting, and occasionally thereafter, the format will be lectures to provide the necessary background for subsequent research topics covered. There will weekly assignments consisting of background reading.
Reading and Discussing Papers The majority of the course will consist of reading and discussing papers from different areas of networking and distributed systems. The focus will be on different styles of research, and how the results are presented. Where possible, I will invite researchers to join our Zoom to discuss their experience and field questions from students.
Project presentations The final week of the class will consist of student presentations of their semester-long research project. Each group will be expected to make 20-minute presentations on their research project, followed by leading a 10–15 minute discussion of their findings.
The official prerequisite for this course is CS 3950, or permission of the instructor. It helps tremendously to have taken CS 3700. This course will be largely discussion- and project-based, and you will be expected to actively participate in class.
The class forum is on Canvas. I typically used Piazza for this purpose, but am using this semester as a trial run of migrating to Canvas for simplicity (and to reduce student exposure to data collection from other parties).

There is no textbook for this course.
Leading the discussion involves two tasks. First, you will make an approximately 10 minute presentation that describes the motivation, goals, and results of the paper. Second, after this presentation and for the remainder of the allocated time slot, you will lead the discussion on the paper. It is you just to ensure a lively atmosphere for discussion, while being careful to stay on the topic of the paper. I will let students sign up to lead the discussion for the papers they choose.
If you are an audience member, you are expected to have read the paper and to participate in the discussion. This is a seminar course, meaning that the point of the course is to have a discussion. Not participating in this part of the course is not an option. The list of the papers will be available on the course website.
This course will have weekly homework in the form of a review of the paper being discussed in class that week. Each review is due by noon of the day it is discussed. All reviews must be submitted via https://northeastern-cs4950sp21.hotcrp.com/
Slip days may be used on the homeworks; absent any use of slip days, homework will be marked 20 points off per day that they are late, up to 2 days.
Each student will form a team of two to identify an approved research project in the area of computer networking. Students first will identify a research area of interest, one or more research questions, one or more testable hypotheses, and an intuition of how to prove or disprove the hypothesis. These items must be written up as a research proposal and shared with the professor. Each team will then meet with the professor to discuss, refine, and ultimately win approval for the project.
After approval, the students must begin initial work on the project and come up with a timeline and milestones for completing the research project by the end of the semester. This must be shared with the professor for feedback.
At approximately one month before the end of the term, students must complete their first milestones. Each group will present to the class, for no more than 10 minutes, their research ideas, initial results, challenges, and lessons learned.
Finally, each team must submit a writeup of their research and findings. Students will review each other's research writeups, address issues that arise from those reviews, and prepare and give a 20-minute presentation on their research.
There are no exams in this course.
You are expected to attend each class meeting, as attendance and active participation during meetings comprises a large fraction of your grade. If you must miss class (e.g., you are ill or have some other obligation), please contact the instructor to discuss how to make up the time missed in class.
The breakdown of the grades in this course is:
Any requests for grade changes or regrading must be made within 7 days of when the work was returned. To ask for a regrade, attach to your work a page that specifies (a) the problem or problems you want to be regraded, and (b) for each of these problems, why do you think the problem was misgraded.
To calculate final grades, I simply sum up the points obtained by each student (the points will sum up to some number x out of 100) and then use the following scale to determine the letter grade: [0-60] F, [60-62] D-, [63-66] D, [67-69] D+, [70-72] C-, [73-76] C, [77-79] C+, [80-82] B-, [83-86] B, [87-89] B+, [90-92] A-, [93-100] A. I do not curve the grades in any way. All fractions will be rounded up.
It's ok to ask your peers about the concepts, algorithms, or approaches needed to do the assignments. We encourage you to do so; both giving and taking advice will help you to learn. However, what you turn in must be your own, or for projects, your group's own work. Looking at or copying code or homework solutions from other people or the Web is strictly prohibited. In particular, looking at other solutions (e.g., from other groups or prior CS 4950 students) is a direct violation. Projects must be entirely the work of the students turning them in, i.e. you and your group members. If you have any questions about using a particular resource, ask the course staff or post a question to the class forum.
All students are subject to the Northeastern University's Academic Integrity Policy. Per CCIS policy, all cases of suspected plagiarism or other academic dishonesty must be referred to the Office of Student Conduct and Conflict Resolution (OSCCR). This may result is deferred suspension, suspension, or expulsion from the university.
If you have a disability-related need for reasonable academic accommodations in this course and have not yet met with a Disability Specialist, please visit www.northeastern.edu/drc and follow the outlined procedure to request services. If the Disability Resource Center has formally approved you for an academic accommodation in this class, please present the instructor with your "Professor Notification Letter" at your earliest convenience, so that we can address your specific needs as early as possible.
Title IX makes it clear that violence and harassment based on sex and gender are Civil Rights offenses subject to the same kinds of accountability and the same kinds of support applied to offenses against other protected categories such as race, national origin, etc. If you or someone you know has been harassed or assaulted, you can find the appropriate resources here: http://www.northeastern.edu/oidi/titleix/
The university has put into place a robust plan to make the campus healthy and safe for all --- but you must do your part. On August 22, all students received an email from Senior Vice Chancellor for Student Affairs Madeleine Estabrook on the expectations for behavior both on campus and off campus. Please read it carefully today.
