Re: [RPRWG] Simulation results



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

 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  - Jon
