Question

Suppose that the five measured SampleRTT values are 106 ms, 120 ms, 140 ms, 90 ms, and 115 ms.

Answer 1

Answer:

a) 100.75,   103.15,    107.756,    105.536,   106.72

b) 5.06,    8,       14.061,       14.43,    12.89

Explanation:

Measured sample RTT values : 106 ms, 120 ms, 140 ms,  90 ms,  115 ms

First estimated RTT value = 100 ms

∝ = 0.125

β = 0.25

First DevRTT value = 5 ms

A)   Compute the EstimatedRTT after each of these SampleRTT values is obtained,

Formula for estimated RTT = ( 1 - ∝ ) . estimated RTT + ∝.sample RTT

B). Compute  the DevRTT after each sample is obtained,

Formula for DevRTT = ( 1 - β ) . DevRTT + β. | sample RTT - Estimated RTT |
