Question 1

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.If audio 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?

Question 2

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
