This paper considers fundamental measurements
which drive TCP flows: throughput, RTT and loss. It is clear
that throughput is, in some sense, a function of both RTT
and loss. In their seminal paper Padyhe et al [1] begin with a
mathematical model of the TCP sliding window evolution process
and come up with an equation showing
that TCP throughput is
(roughly) proportional to 1/RTT √p where p is the probability
of packet loss. Their equation is shown to be consistent with data
gathered on several links. This paper takes the opposite approach
and analyses a large number of packet traces from well-known
sources in order to create a data-driven estimate of the functions
which relate TCP, loss and RTT. Regression analysis is used to fit
models to connect the quantities. The fitted models show different
behaviour from that expected in [1].

This paper tries to establish the relationship between TCP throughput and fundamental qualities like round trip time, flow size and loss. The approach is data driven considering large numbers of publicly available data sources.
