Question

Frame arrives at a 100 mbps channel for onward transmission. if channel is busy when a frame arrives, it waits its turn in a queue. frame length is exponentially distributed with a mean of 10,000 bits/frame. for each of the frame arrival rates, find delay experienced by the average frame,including both queueing and transmission time

Answer 1

For this problem, use a formula from this chapter, but first state the formula. Frames arrive randomly at a 100-Mbps channel for transmission. If the channel is busy when a frame arrives, it waits its turn in a queue. Frame length is exponentially distributed with a mean of 10,000 bits/frame. For each of the following frame arrival rates, give the delay experienced by the average frame, including both queueing time and transmission time.

(a) 90 frames/sec.

(b) 900 frames/sec.

(c) 9000 frames/sec.
