[ih] TCP RTT Estimator

[David Finnigan]

Craig, I know that you did a lot of important work and (co)authored some 
papers on this subject. I am mostly interested in why that smoothing 
algorithm was initially chosen, and what consideration (if any) had been 
given to other methods of estimating round trip time for the purpose of 
computing an RTO.
