For the network-of-queues with probabilistic routing given in Figure 19.3, sup- pose that that each server serves at an average rate of 10 jobs/sec; that is, p= 10, Vi. Suppose that r2 = r3= 1. Suppose that p12 = P2,out = 0.8, P23 = P13 = 0.2, P1,out= 0, and p31 = 1. What is the maximum allowable value of ry to keep this system stable? Example: Network of Queues with Probabilistic Routing This is shown in Figure 19.3. Here server i receives external arrivals ("outside arrivals") with rate r. Server i also receives internal arrivals from some of the other servers. A packet that finishes service at server i is next routed to server j with probability pij.
