This course provides an introduction to computer networks, focusing especially on their architecture and on the algorithms that enable both large-scale networks (such as the Internet) and smaller scale networks (such as ad-hoc networks connecting personal devices).

This course assumes that students have taken an introductory programming course and can program in Python. We also assume that students have taken an algorithms course (e.g., CSCI-UA.0310) and are familiar with basic graph algorithms (e.g., determining whether a graph is cyclic, computing shortest paths, trees, etc.).


No textbooks are required for the class. However, if you prefer having a textbook we recommend both

  • Kurose and Ross: Computer Networking: A Top-Down Approach (7th Edition).
  • Peterson and Davie: Computer Networks: A Systems Approach (Version 6.0 available online)

When possible we will provide chapters corresponding to the lectures.

Additionally you might benefit from looking at slides and lecture notes from:
