Chapter 9, Problem P10P

Explanation of Solution

Similarity between the estimating average delay and round trip time:

The above mentioned procedure will have same formulas and both results in the exponentially decreasing weights for the past samples.

Estimating average delay:

The generalized formula for the n sample is denoted as:

${\text{v}}^{\left(\text{n}\right)}\text{=}\text{u}{\displaystyle \sum _{\text{j=1}}^{\text{n-1}}{\left(\text{1-u}\right)}^{\text{j-1}}}\left|{\text{Δ}}_{\text{j}}\text{-}{\text{d}}^{\left(\text{n-j}\right)}\right|\text{+}{\left(\text{1-u}\right)}^{\text{n}}\left|{\text{Δ}}_{\text{n}}\text{-}{\text{d}}^{\left(\text{1}\right)}\right|$

Estimating round trip time:

The generalized formula for the n sample is denoted as

$$
