Necdet:
The models we previous released are specific for BE traffic only. I
have recently extended the simulator to handle the high priority traffics,
and have observed some problems for the high priority traffics as Jon mentioned.
We are in the process of trying different alternatives to fix them, and
should be able to share the simualtion results and ideas with you soon.

Necdet, No,
I didn't use the AT&T models, I programmed it myself.Annex
G notes that the formula over and underestimates thereal
value. I will try to get a better estimation, and check thatwith
the simulations. Regards,Jon -----

Jon,
Thank you for the good work. It seems like our formulas in Annex G is
off quite a bit specially for conservative mode. Did you use the models
from AT&T? If there is no modeling error, we need to find out the root
cause of it and modify our formulas.
Thanks.

Yes,
it is better to change only one parameter at a time. New results with fixed
500km ring are here:http://www.ikn.tuwien.ac.at/~nthuma/simRes2.pdf

Jon,
Thank you for running these simulations. These are very valuable. The
only think that is not clear to me from the result is whether the buffer
requirement is linearly increased with number of nodes or with the size
of the ring. Can you please run the same simulations for a fixed size ring
say for 500km with varying number of nodes as in your graphs? After that
we can determine whether the number of nodes affect the buffer requirements
or not and based on that we can modify the formulas if necessary.
Thanks.

Dear
all, I finished the simulations
about the maximum stq buffer occupancy withfixed values for stqLowThreshold
and stqHighThreshold andstqFullThreshold set to infinity, as Necdet proposed.
You can get the results here:http://www.ikn.tuwien.ac.at/~nthuma/simRes.pdf
