SCE signals start earlier than CE. As you = increase the number of flows the number of CE signals increases, and SCE = signals decrease until eventually all packets have CE markings and SCE = is not used. It=E2=80=99s still surprising though that with one flow that there=E2=80=99= s really just one CE signal then that=E2=80=99s it, yet the rate is = limited without drops. Is that somehow caused by TSQ?
