Not using ecn. I did one ecn run but didn’t see much change. I did more runs at 950mbit- 20ms, 50ms 100ms and added a chart at the bottom of rtt vs fairness (same doc, link for reference):
There seems to be a weird asymmetry that happens sometimes at rtt 20ms and rtt 50ms. One run at 20ms (right after rebooting) looked good but an earlier one didn’t. Three runs at 50ms all showed some level of asymmetry.
I’ll have to move on to other work, but the results still show fairness working pretty well at 100ms. It sometimes works well at other rtts, but there are variations and sometimes asymmetries. It’s hard to pull apart.
