Communication Networks - Semester A 2012/13

The course introduces fundamental concepts of computer networking. We will also discuss Internet protocols and applications.
We will mostly follow the textbook "Computer Networking" by Kurose and Ross (See in the textbooks section below).

Wireshark's website
On the Debian machines in our school you will find it under Applications -> Internet.

Closed-books final exam will be held on 14.02.2013, 09:00.
You may bring 4 pages (i.e. 2 two-sided sheets) with you to the exam.

Please see the exam instructions.

A collection of past exams is available here. Please note:

1. The topics covered are not identical in all years.
2. Some errors were previously found in the published solutions, so don't take them for granted.
