71% 9:12 MM x Networked L a Networked Life: 20 Questions and Answers by Mung Chiang Chapter 13: How does traffic get through the Internet? Problems 13.1 Packet switching (a) Stalistical multiplexing Suppose you have a 10 Mbps link shared by many users. Fach user of the link generates 1 Mbps or data 10% of the lime, and is idle 90% of the time. ir we use a circuit switched network, and the bandwidth allocation is equal, how many users can the link support? Call this number N. Now consider a packet switched network. Say we have M users in tolal, and we want the probability of a a user being denied service be less Wrile down the expression that must be solved in the form of f (M, N) 0,01, Solve this numerically for M. (Hint: Use the binomial CDR.) (b) Resource pooling We will consider modeling a shared resource and
