I happen to be at Infocom in Toronto, VPN’d into Cisco San Jose, and did a ping to you: ping -c 10 swm.pp.se PING swm.pp.se (212.247.200.143): 56 data bytes ... --- swm.pp.se ping statistics --- 10 packets transmitted, 10 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 249.368/342.038/456.376/71.902 ms 3 seconds is unusually high, although naval satcom is frequently in the 1.5-2.5 ms range. But I have a sample that I measured in a Dublin hotel that observed standing latencies of around 280 ms to San Jose, frequent latencies of seven seconds, and a peak of 9286 ms. Yes, the hotel DSL was horrendously misconfigured. It makes a great graphic for presentations. > -- > Mikael Abrahamsson email: [email protected] > > _______________________________________________ > aqm mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/aqm ---------------------------------------------------- The ignorance of how to use new knowledge stockpiles exponentially. - Marshall McLuhan
