CSCI 1680 is an undergraduate course in computer networks. We will cover the technologies supporting the Internet, from Ethernet and WiFi through the routing protocols that govern the flow of traffic, and the web technologies that are generating most of it. A major concern is understanding the protocols used on the Internet: how they work, their shortcomings, what the issues are, and what improvements are on the horizon.

Prerequisites: CSCI 0320, CSCI 0360, or consent of the instructor.

  • Lecture time: Tu/Th 10:30-11:50
  • Location: CIT 368

Course Conventions

The course uses a number of conventions which are noted here.

Course Policies

Collaboration Policy

The collaboration policy is available as a handout. You must print, read, and sign the collaboration policy before returning it to a TA so that you can receive credit for the assignments.

Incomplete Policy

Incompletes are granted only under exceptional circumstances (e.g. severe illness, death in the family, kidnapping, etc.; too heavy of a course load is not sufficient reason for an incomplete). Getting a dean to certify your reason for requesting an incomplete helps, but is not sufficient.

Late Policy

Students will be allowed a total of two (2) late days to be used on homework assignments free of charge. Late days may not be used for the programming assignments. Students will be penalized 25% of the assignment's value for each day it is late (but you will not be penalized for more than the assignment's value).
