Carleton University Department of Systems and Computer Engineering SYSC4005/5001 Simulation of Discrete Event Systems First In Class Exam (5:30pm -7:00pm) February 12, 2009 Problem 1 Perform a manual simulation for the two-processor system shown below. Incoming packet inter-arrival times are assumed independent of each other and distributed as in table 1. Arriving packets that find both processors busy are departing from the system and assumed blocked (i.e. lost). Service times in processors s1 and s2 are independent and identically distributed with the distribution as in table 2. Table 1 Table 2 We assume that 7 packets arrive and we simulate the system till it empties. The service times and inter-arrival times are derived using the random digits from the following table. When both processors are available processor one is used first. a) (5%) Generate the necessary inter-arrival, actual arrival and service times for all packets and fill the table Inter-arrival times 1sec 2sec 3sec 4sec
