[Example: For link X, can we say that most packets/bytes stay on that continent? Or that most packets have a minimum end-to-end delay of at least S seconds? Or that most packets on that link during this period of time traverse more than one congested link on their path from source to destination?]
For round-trip time measurements greater than 500 ms, to what extent is this delay due to queueing delay? to routing problems? to delay at the end-node?
Answers. Quick summary, so far: A range of more than 10:1 in round-trip times seems common, but with most (85%, in one case) of the connections having round-trip times between 15 and 500 ms.
Quick summary: Deployment is increasing rapidly, both for web
browsers and for web servers.
Quick summary: There is a significant deployment of NewReno TCP, as
compared to Reno or Tahoe TCP.

already has pointers to Curtis Villamizar's 1994 paper
on "High Performance TCP in ANSNET", and to Sean Doran's web page
showing RED turned on at a site at Ebone.
* WRED is enabled on Cisco GSRs on overloaded links at AS1 (Genuity), to reduce queueing delay. Experience has been positive. (Reported by Derek Fonda of Genuity, October 2000.)
