Homework ? You mean the question is at a high level.
I use R. It is just the simulation part that I am investigating.
Several
papers on Capacity Planning that I am working on are useful for
analyzing log traffic using R for GOF tests etc. But I am not able to
find many papers on using R or r-java to generate traffic that
simulates
distributions. SciPY could be useful here but it looks like
interfacing
R and Java can help.
Maybe I am on the wrong track here but the only other option seems
to be
expensive simulators.
I'm sure Rui would be happy to get a small consulting fee to show you
how to do it in one line of R code.

Hello,
Homework?
There's a no homework rule but see inline.

Hi,
I am looking for some assistance with these requirements.
We
are trying to simulate web requests to hit a web applications. Let's
assume I have a url to hit that requires a username and password.
1. These web requests should have exponential inter arrival times.
Poisson process. See any introductory text.
And see the help page for ?rexp
2. Generate self-similar traffic. I am not very sure about the
properties of this traffic. Is Variance Time plot used for analyzing
if
the data received from this simulation is self-similar ?
See the argument 'rate' in the help page above. Set it to a single
value.
How does R help in creating a program that can generate this
traffic ?
Simply by making of this a straightforward to program an assignment.
Hope this helps,
Rui Barradas
Thanks,
Mohan
