Let 0, 50, 100, 150, 200, 250 specify the timestamps of 6 consecutive VoIP packets and 26, 71, 133, 171, 239, 276 specify the corresponding received times of the same six packets. a. Using the exponentially weighted moving average, find the estimated delay after every packet is received by the client (except the first one).
Use the formulla di = (1-α)di-1 + α(ri-ti)di=(1−α)di−1+α(ri−ti) where i=1, 2, ,5 α=0.2 r1=71, t1=50t etc.
b. Using the exponentially weighted moving average, find the estimated deviation of delays calculated in the previous part. Use the formula vi=(1-β)vi-1 + β ri-ti-di| where β=0.1:i=1,2,…,5, v_0=0
c. Using the calculated values in previous parts and the following formula, schedule the playout time of packets with timestamps 50,100,…,250:
playout time= ti+di+Kvi
where K = 5.
d. Does there any packet miss its playout schedule time; i. e. is there any packet whose playout time is scheduled earlier than its arrival time? If so, what should be the minimum value of K so that we have no packet playout loss.
