Messages arrive randomly at rate 0.5 per unit time at a communication network with 3 nodes (computers). Each computer can queue messages and service-times are exponential with mean m[i] at node i. These values are given in the column headed m[i] in the table below. On service at a node a message transfers to one of the other nodes or leaves the system. The probability of a transfer from node i to node j is p[i,j]. Node 4 means "outside the system" so a message will transfer out of the system from node i with probability p[i,4].

Your task is to estimate the average time taken for jobs going through the system and the average number of jobs in the system.
