Title: RE: [RPRWG] Fairness Ad-Hoc

We have run David and Harry’s original scenario. The results can be found at

http://www.ifi.uio.no/~steing/rpr/sim_res.ppt

We also doubled the STQ size, and found a large increase in the A1 jitter.

A1 jitter and A0 jitter seems to be the same. The A1 jitter is probably mainly caused by large negative shaper D values, as several people now have pointed out. We will try to implement shaping of STQ traffic tomorrow. Class A0 jitter will then be studied in more detail.
