 |
An interview
about our Computer Networks and Wireless Networks Laboratories. |
30-April-2007
|
Here is the
best projects of HW4 (e-mail
client, SMTP/POP3 mail client). |
5-April-2007
|
The first midterm: 10 April 2007, Tuesday,
at 13:00, 2-hour exam, in class. |
|
The topics for the exam: Chapters 1, 2,
3 (up to page 228, including Chapter 3.4) and
Ethereal (but Lab topics are not included) |
|
Look at
this page for questions asked in previous years and their solutions. |
|
Examine and study some of these
best projects (typical HW2 Solutions) by running them to understand real TCP/UDP socket
programming. |
|
The homework assignment 5:
HW5 , return your solutions until
12:00 on Monday, 9 April. Late assignments will not be accepted. |
|
The solutions of the homework assignments:
HW1 solutions ,
HW3 Solutions,
HW5 Solutions. |
28-March-2007
|
The first programming assignment HW2
is updated after your questions related to grading and the program
messages. Please download HW2 again. |
|
Concentrate on TCP/UDP socket and network programming parts of the
program, not GUI and other Java related problems. For example, if you
have some difficulty in reading from a text file (quotes.txt) in Java,
just use an array to hold your quotes for the initial version of the
program. Add more features later, after you have done the required
networking features of the program. |
|
You should send an e-mail to me to get an appointment time for
Friday HW2 demo in the lab. Write the names of your project team and
your section (English or Turkish). Your time for demo will be sent to
you and your team will come to the lab at your time (15 minutes before). |
27-March-2007
|
The program demonstrations will be held on Friday, 30 March, between
14:00 - 16:30 in the Lab. No late assignments will be accepted. |
14-March-2007
|
Please take your first and second homework assignments,
HW1 and
HW2, return your solutions on their
due dates. Late assignments will not be accepted. |

Welcome to
CENG 362 Comuter Networks!
This course has a top-down approach (from
Application Layer to Physical Layer) focusing on the Internet and
lab experiments, networking applications using network analyzer (Ethereal), and
a high level programming language, Java. |
|
In this course,
you will learn
IP
packets journey from Application Layer down to Physical Layer
through net past routers, firewalls and transatlantic cables and
wireless communication media. It will be
interesting to watch the following 12:40 minute Warriors-of-the-Net movie before we start this journey. You can
download this movie from
here or
its web site. (optional)
|
|
Your course and lab TA
Mustafa Sarıöz (for CENG
362) and
A. Volkan Gürel (for
BILM 362) will make their announcements
on their web pages. The weekly lab schedule, solutions, and announcements
related to his activities will be posted
there. Start to visit their web pages regularly.
