Next round trip time = $\alpha$ * Initial round trip time + ( 1 - $\alpha$  )*Actual Round trip time

                                      = 0.9*(90) + (1- 0.9)*86

                                      = 89.6 ms

Na462  Is it correct answer ??

It is asked to find the Next Round Trip Time provided with the Initial Round Trip Time(IRTT) and Actual Round Trip Time(ARTT) and Smoothening Factor α. So by using the Basic Algorithm for TO(Timeout Computation)

NRTT = α(IRTT) + (1-α)ARTT

So the formula becomes;

NRTT = 0.9(90) + (0.1)86

NRTT = 81 + 8.6

     = 89.6ms

Yes Magma its correct

Answer 1

using timeout timer basic algorithm which is dynamic and used to avoid congestion

NRTT=(alpha)*IRTT+(1-alpha)*ARTT;

ARTT=actual round trip time,ARTT=actual RTT and NRTT is next RTT

NRTT=(.9)*90+(.1)*(86)

NRTT=89.6
