Analyze packet delays and playback buffer data in a multimedia transmission scenario. Determine delays of packets 2-8, identify packets not arriving in time for playout, and calculate minimum playout delay for timely arrival. Evaluate data in the playback buffer at specific times in the transmission process.
E N D
a. What are the delays (from sender to receiver, ignoring any playout delays) of packets 2 through 8? Note that each vertical and horizontal line segment in the figure has a length of 1, 2, or 3 time units. 2 3 4 5 6 7 9 10 11 12 13 14 15 16
b. If audio playout begins as soon as the first packet arrives at the receiver at t = 8, which of the first eight packets sent will not arrive in time for playout?
c.Ifaudio playout begins at t = 9, which of the first eight packets sent will not arrive in time for playout? d. What is the minimum playout delay at the receiver that results in all of the first eight packets arriving in time for their playout?
Question2 • See figure 29.17 what is the amount of data in the playback buffer at each of the • following times? • a. 00:00:17 • b. 00:00:20 • c. 00:00:25 • d. 00:00:30
