Announcements

8.2.2007	Final grades: Group 2 Group 3. Here is a short explanation of how the grades were calculated.

3.2.2007	The grade exercises were published in the Assignments page. Appeals should be sent to David by email only! Please attach a scan of your homework.

30.1.2007	Here is the solution to the exam.
21.1.2007	Due to the senior staff strike, you can submit theoretical exercise 4 tomorrow, January 22nd. However, as mentioned before, we cannot guarantee the exercises will be returned before the exam if you submit after today at 14:00.
15.1.2007	Please note if you want to make sure that your theoretical exercise 4 will be returned before the exam you must submit it before 14:00 on 21/1. We cannot guarantee that submissions made after 14:00 will be returned before the exam.
4.1.2007	The submission date for Programming assigment 3 was postponed to 14.1.2007
3.1.2007	A fixed recitation was uploaded, I apologizes for the mistakes. Theoretical assignment 4 has been published. Submission due 21.1.2007.
26.12.2006	A misleading line was removed from the description of Programming Assginment 1. You are required to implement GBN, so no buffering is needed.
19.12.2006	Programming assignment 3 has been published. Submission due 11.1.2007. Please note the extra work for groups of three people.
19.12.2006	Theoretical assignment 3 has been published. Submission due 4.1.2007.
19.12.2006	Due to a strike, there will be no class Thursday. You are all welcome to the Tuesday class.
29.11.2006	Assignment grades were published.
24.11.2006	Due to concerns raised by some of the students we have changed the guidelines for submitting the programming homework. You are now only required to make sure the files can be READ from another account.
23.11.2006	Please note that some students are not submitting the homework in pairs. While you are allowed to submit the work alone, this is very unrecommended. An email was sent to all the students who submitted alone, so you can try to pair with someone else. For the very few teams who were allowed to submit in a group of three - note that your team will have to do an extra exercise at the end of the semester.
21.11.2006	Theoretical assignment 2 has been published. Submission due 6.12.2006.
19.11.2006	Programming assignment 2 has been published. Submission due 13.12.2006.
5.11.2006	The link to the 3rd recitation was fixed. Exams from previous years were added.
2.11.2006	Theoretical assignment 1 has been published. Submission due 22.11.2006.
30.10.2006	Programming assignment 1 has been published. Submission due 15.11.2006.
22.10.2006	Welcome to Communication Networks course.
