However, are 4 flows going to provide you stable working conditions in such a way that the bottleneck’s buffers are entirely full over an extended period without fluctuations due to the congestion-response of the individual flows? Also, what is the convergence time to reach stable working conditions and full buffer utilization at 4 flows?</div><div><br></div><div>Now, that being said. I don’t think that the exact number of flows is that important. They just need to be enough to fill the buffers in a stable way. All nit-picking on the number of flows just distracts us from actually solving problems on the Internet.</div><br><blockquote type="cite"><div><div>Anyway, is the structure of networkQuality<br>changing any in ippm?</div></div></blockquote><div><br></div><div>Yes, the IETF-draft is continuously evolving.
