Jon,
stqSize(0) in this graph is a lot smaller than the one that you sent
earlier (simRes2.pdf). Is there a conversion problem here (byte vs bits
etc)?
Another information that could be very valuable is how long is the priority
inversion when we fix the stq size to the values given in the draft. A
delay jitter histogram would be very useful. I am especially interested
in jitter values exceeding 2 x 256 x MTU time.
Thanks.

Jon,Thanks
for your interesting work. A couple of questions (if it is not too much..:):Do
you have the values of the localFairRate for station 0 ? Can you make a
graph that shows how this value changes with time for the aggressive and
the conservative modes ?Leon
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
