MAT 201B -- Media Networks and Services
Homework Assignment #1
Due in Class on Thursday 10/28/99
You are given three files. These have been tested and verified to work.
The three (plus one extra credit) parts of this assignment are:
- Understand the UDP client/server code and implement some
- Develop similar TCP client/server code.
- Develop similar code, but in JAVA, for both the UDP and
TCP echo clients/servers.
- Implement non-blocking UDP echo server/client in C.
The first part is likely to be the most vague part of the
assignment. The idea is that since I've given you the code
for doing the UDP echo server and verified that it compiles
correctly, there isn't much left to do. Therefore,
the goal of this part of the assignment is to get you
to understand what each step of the code does. To
a certain extent we did this in class, but doing it
will give you additional experience and understanding.
As a result, this part of the assignment asks you to do
two things: (1) report questions/answers you
generated while experimenting with this code, and
(2) modify the code to provide some additional
functionality and then document what you've done
The hardest part is always the first part. The
additional components of the assignment are relatively
straightforward and should follow closely from the
You should turn in a hard copy of all files and
any written answers.
In addition for correctness, points will be given based
on how well code is written and documented. NOTE: good
code/documentation does not imply that more or less is
better. The goal is to be efficient, elegant and succinct!
