4. One hundred voice sources are multiplexed at an ATM access buffer. Each voice source has an average talk spurt length of 0.8sec. Its average silent interval is 1.2sec. (a) What is the probability that a voice source is in talk spurt? (b) When in talk spurt, a source generates ATM cells at the rate of 100 cells/sec. Find the link capacity C₁, in cells/sec, if the link utilization p is to be set at 0.7. (c) Determine the overload region for the 100 sources, based on (b) above. (d) Fluid analysis is used to size the buffer. Approximate the survivor function by the G(z) ¹. What is r in this case if the unit of zis cells. 4.
