Problem 1: Examine Figure 1, and consider time increments in milliseconds (ms). A sender begins sending packetized audio periodically at t=1. The first packet arrives at the receiver at t=8. Figure 1 a. What are the delays, in ms, from sender to receiver (ignoring any playout delays) of packets 1 through 7 ? b. If audio playout begins as soon as the first packet arrives at the receiver at t=8, which of the first seven packets sent will not arrive in time for playout? ( 2 points) c. If audio playout begins at t=9, which of the first seven packets sent will not arrive in time for playout? d. What is the minimum playout delay (in ms) at the receiver that results in all of the first seven packets arriving in time for their playout
