CS3611 (Spring 2024): Computer Networks


Course Description:

This course will introduce students to the key concepts underlying wired and wireless networking with a focus on the discussion of the layered architecture of the network protocol. A variety of case studies will be drawn from the Internet, combined with several practical programming exercises. At the end of the semester, students are expected to understand, several concepts, including the Internet architecture, HTTP, DNS, P2P, Sockets, TCP/IP, BGP, Routing protocols, wireless and sensor networking, WiFi, cellular and satellite networks, security, etc., with the ability to analyze and design protocols and algorithms in networking systems.

In this semester, we will have a series of homeworks, which will help you better understand the concepts and protocols discussed during the lectures.

Instructions:
  • You are expected to carry out the homeworks by yourself.
  • For each homework, you are expected to submit a pdf file containing your answers to all questions via Canvas.
  • Your answer file should be written in English, otherwise it will not be graded.
  • Your answer file should be named as "StudentName_StudentID_HomeworkIndex.pdf". For example, HaimingJin_5080309195_Homework1.pdf for Homework 1.
Assignments:

In this semester, you are expected to carry out several lab assignments to obtain hands-on experience on computer networks. Specifically, the labs will offer you the opportunity to getting familiar with Wireshark, Mininet, socket programming, NFS, gRPC, etc.

Instructions:
  • You are expected to carry out the labs by yourself.
  • You will not need to go to an actual lab room for the labs, as they could be finished using your own PCs.
  • For each lab, you are expected to submit a report and the corresponding code via Canvas.
  • Your report should be a pdf file written in English, otherwise it will not be graded.
  • Your report should be named as "StudentName_StudentID_LabIndex.pdf". For example, HaimingJin_5080309195_Lab1.pdf for Lab 1. If there are multiple files (e.g., report and code) to be submitted for the same lab, please put all your files in a .zip file named as "StudentName_StudentID_LabIndex.zip".
  • Each lab assignment normally contains a tutorial and several questions. The tutorial will instruct you to set up the basic environment and install the tools necessary for the lab. In your report for each lab, you are expected to provide answers to all questions by using the installed tools or writing additional codes as required.
Assignments:
  • Lab 1: Set up Environment and Test Basic Softwares
