They are well known to be using bbr and experimenting with bbrv2. So I fired off a capture during a big dropbox download... It negotiated ecn, my fq_codel shaper and/or my newly ath10k fq_codel's wifi exerted CE, osx sent back ecn-echo, and the rtt results were lovely. However, there is possibly not a causal relationship here, and if anyone is bored and wants to scetrace, tcptrace or otherwise tear this cap apart, go for it. http://flent-fremont.bufferbloat.net/~d/db.cap --=20 Make Music, Not War Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-435-0729
