S-38.188 Computer Networks (Spring-04)
Project work part 2
General guidelines
- The assignments must be solved in groups of two.
- All answers must be the students' own and original
contribution.
If the answers consist of copy pasted material from the book, lecture slides, Internet or other students'
answers, the student group will not pass the project work and
other measures may also be taken.
- D-line is Wednesday March 24th 2004 at 12:00. Reports may be
returned in exercise class or into the box under the notice board in the
G-wing.
- Reports may be returned in English or Finnish.
- You may ask questions concerning the
simulation during exercise classes on Wednesdays from 12-14
o'clock (S5) on 10.3. and 17.3. By default questions asked by e-mail will not be
answered, it is assumed that students use the exercise class for asking questions.
- If necessary a FAQ page will be created on the web page
concerning the problems: http://www.netlab.hut.fi/opetus/s38188/2004/harj/FAQ.shtml. In the grading it is assumed that you
know what is mentioned in this FAQ.
- The third part of the project work (done with the same group of 2) can be submitted only
if the first and second part have been successfully passed by the
group.
- Grading results of part 2 of the project work will be announced
latest on Friday April 2nd 2004.
Grading
- Grading results
- Part 2 of the project work is graded as pass or fail. (Part 1 of the project work is worth 22 points. To pass part 1 you need 12 points.
From part 3, you can obtain a grade of 0, 1, 3, or 5. If you get 17 or more points from part 1, your passing grade from part 3 is increased by one.
Then the possible grades for the project work are 0, 2, 4, or 6.)
The final grade of the course is 25% the project work grade and 75% the exam grade.
- Note that if you do not pass part 2 of the project work, you may not do the
third part of the project work and may thus not take the exam nor finish the course. Next chance is then spring 2005!
General guidelines-ns2
- Part 2 will be carried on using the ns2 simulation tool.
http://www.isi.edu/nsnam/ns/
You should start familiarizing yourself with the tool as soon as
possible.
http://www.isi.edu/nsnam/ns/tutorial/index.html
- Weekly times are reserved from the UNIX workstation classrooms
http://www.ee.hut.fi/unix/
of the department (B201 and B215) for you to do your
assignment Wed 12-18 during the period 10.3.-28.4.
- The simulation program is installed on the SunOS 5.8 sun4u architectures in room B215.
You can use command uname -srm to verify the
architecture.
- In order to use the workstations you need to have the access right of the department.
If you are a student of the department and you have a UNIX user
name, you should have the access right of the department
automatically. Students from other departments should check if
they can log on the workstations. If you do not have access,
please e-mail me with the subject of your e-mail
containing the text "S-38.188 username xxx", where xxx is your
username. I will take care of registering your username.
- You can also install ns2 on your own computer, but the course personnel
will not be able to give more than minimal support on how to do it.
Using ns2
- Connect yourself to a workstation, where ns2 is installed.
- To load the program to your own path, give the command
source /p/gen/courses/S38/S38.188/use
The script should tell you what UNIX shell you are using and what
command you should give next (same source command but file
use replaced with use.xxx). If you have a bash
shell, then you give the source command with the file
use.sh.
- Run the simulation file saved as xxx.tcl with the command ns xxx.tcl
- In order to save disk quota use a tmp directory for temporary files and compress your output files with
gzip.
