1. Consider the TCP procedure for estimating RTT. Suppose that α = 0.1. Let SampleRTT₁
be the most recent sample RTT, let SampleRTT₂
be the next most recent sample RTT, and so on.

a. For a given TCP connection, suppose four acknowledgments have been returned with corresponding sample RTTs: SampleRTT₄, SampleRTT₃, SampleRTT₂, and SampleRTT₁. Express EstimatedRTT in terms of the four sample RTTs.

b. Generalize your formula for
n
sample RTTs.

c. For the formula in part (b) let
n
approach infinity. Comment on why this averaging procedure is called an exponential moving average.
