a. Consider an audio conference call in Skype with N > 2 participants. Suppose each participant generates a constant stream of rate r bps. How many bits per second will the call initiator need to send? How many bits per second will each of the other N – 1 participants need to send? What is the total send rate, aggregated over all participants?
b. Repeat part (a) for a Skype video conference call using a central server.
. Repeat part (b), but now for when each peer sends a copy of its video stream to each of the N – 1 other peers.
a)
Given data:
Consider an audio conference call in Skype with N > 2 participants
That means, both schemes are used approximatley 25% more bandwidth.
Suppose each participant generates a constant stream of rate r bps.
Assume the first scheme has a playback delay of 5 packets.
So, the second scheme has a delay of 2 packets.
