Consider the following network. In this network, three flows arrive to Section 1 with average flow rates; -10kbps, A=2kbps, A3=4kbps, and three flows arrive to Section 2 with average flow rates; A4-3kbps, As-5kbps, A6-2kbps. The number of packets in Section 1 and Section 2 are N=20, and N=50 packets, respectively. Packet sizes are fixed and 1000 Bytes. Calculate the average delay in (i) Section 1, (ii) Section 2, and (iii) whole system (i.e., Section 1 and Section 2 are combined). A = 10 kbps A = 2 kbps Section 1 Section 2 A = 4 kbps A = 3 kbps A5 = 5 kbps = 2 kbps
