Question 10 The current estimate of the RTT (round-trip time) is RTTo 5.0 ms and the initial value of the mean deviation (dispersion) Do = 0.7 ms. The further measurements resulted in the following values for RTT: M₁ = 3.8 ms; M₂ = 3.8 ms; M3 = 3.8 ms; M4 = 2.3 ms; M5 = 2.3 ms; M₁ = 5.0 ms; M7 = 10.0 ms. Using the Jacobson algorithm cal- culate the RTO corresponding to each measurement (assume the smoothing factors a = y = 0.875 for calculations of RTT and D, respectively). Explain the impact of the value of the parameter a on evaluation of the RTT.

The current estimate of the RTT (round-trip time) is RTTo 5.0 ms and the initial
value of the mean deviation (dispersion) Do = 0.7 ms. The further measurements
resulted in the following values for RTT: M₁ = 3.8 ms; M₂ = 3.8 ms; M3 = 3.8 ms; M4
= 2.3 ms; M5 = 2.3 ms; M₁ = 5.0 ms; M7 = 10.0 ms. Using the Jacobson algorithm cal-
culate the RTO corresponding to each measurement (assume the smoothing factors a
= y = 0.875 for calculations of RTT and D, respectively). Explain the impact of the
value of the parameter a on evaluation of the RTT.
