[e2e] TCP Congestion Avoidance

[Scott Johnson]

I was wondering if there was a feeling among the list members if the 
approximation for TCP throughput developed by Matthew Mathis, Jeffrey 
Semke, and Jamshid Mahdavi in their 1999 (I believe it was 1999) paper 
entitled "The Macroscopic Behavior of the TCP Congestion Avoidance 
Algorithm" is still valid?  I am particulary curious if folks feel that 
it could be approximated as:  throughput <= ~0.7 * MSS / (rtt * sqrt 
(packet_loss)).  This representation came from a paper by Phl Dykstra 
titled Gigabit Ethernet Jumbo Frames (  
http://sd.wareonearth.com/woe/jumbo.html  ).

The topic came up at work and I didn't know if , with the passage of 
time, people still feel it is valid.  I would sincerely appreciate any 
comments.
