The following network is considered where Source 1 produces a Poisson stream of packets at an average arrival rate of 8000 packets per second, and Sources 2 and 3 produce Poisson streams of packets each at an average arrival rate of 2000 packets per second. R3, R2 and R1 can forward on each outgoing link packets of average size 1250 bytes at 100Mbits/sec. The distribution of outgoing traffic for routers R1 and R3 is describe in Table 2. Figure 4: Exercise 3 - Model Calculate and simulate the overall average delay experienced by packets: - arriving in sink 1 , from each source 1 and 2 ; 5 4 QS3 - QUEUEING SYSTEM 3 - arriving in sink 2, from each source 1,2 and 3; Note: In the calculation of the average delay experienced by packets between a source and a destination, when there are multiple paths between source and destination, the weighted average of the delays experienced on each path should be calculated.
