CIS 432/532 Introduction to Computer Networks - Fall 2003

Announcements

All announcements will be emailed to the class mailing list before being posted here. You must add yourself to the class mailing list to receive these announcements. This can be done by executing the command grpmod -au username cis432 where username is your username.

15 October: Program #1 Code and Binaries Available

The class website now has a Sample Code section with example usage of the socket functions you will need. The DuckChat header file, a Makefile, and Solaris binaries for the client and server are available from /cs/classes/03F/cis432/code/program1 on the department systems. You can use the provided client and server to test your programs as you develop them.

31 October: program submissions

Some students have asked how to submit the program once it is complete. Please submit your source code via email to the GTF. Please include a README file that includes your name and any special information I need to know about your program. This includes compilation instructions and any known limitations of your program.

The program is due on midnight at the end of Tuesday.

4 November: Homework 2 solutions

Astute students have observed some small errors in the solutions to Homework #2 previously posted to the class website. In problem 6, an additional RTT_0 was missing to account for setting up the TCP connection to the webserver. In part B of problem 13, the change in Beta was not reflected in the solution originally posted. Also on problem 13, the problem states that the LAN transfer time may be ignored.

If your homework had the correct solution on your homework, please bring it to the GTF for the course to have your grade adjusted.

5 November: Program #1 solutions

I have sent email acknowledging the Program #1 submissions I have received. If you submitted your program, but did not receive an acknowledgement, please contact me.

The source code for the sample client and server are now online at /cs/classes/03F/cis432/code/program1.

6 November: Program #2, Homework #3, Chapter 4 slides now online

Programming Assignment 2, Homework 3, and the slides for Chapter 4 are now all available online.

6 November: Program #2 undergraduate topologies available

For the undergraduate version of Program 2, I have placed a script to generate topologies in the code directory of the class website. It's available here:
http://www.cs.uoregon.edu/classes/03F/cis432/code/program2/

or you can access it directly on the department Solaris machines:
/cs/classes/www/fall/cis432/code/program2

This script starts up several servers, joining them together in different topologies. It will start up 3 different topologies, although you will probably only want to test with one of them at a time. At the beginning of the script is a variable that you must change to point to your server binary.

26 November: Program #2 extra credit

An extra credit section has been added to the graduate programming assignment. Also, the extra credit section in the undergraduate assignment has be elaborated.
