Please write an explanation for each step.
Consider two packets, each of length, L bytes sent one of often after the other from Alice to Bob in the following network. S4,32 and sa ane stone-and- forward routers with negligible packet processing time. Bul and Bus are bandwidth. The propagation delay of each four links are Tpms. Bar | Alice BWI BW2 R$1 BWI S2 53 Bob as a) Draw a timing diagram for packet pair in the network assuming other interfering traffic in any of the links. Clearly label all e BWI) BW2. Also assume that there is the values. b) Find an ex expression for the parket pair disperete dispersion, which is defined as the gap between the arrival of the last bit of the first parket and the first bit of the second packet at Bob 1 c) Finel o the pocket pair dispersion for a network with ta tms , BWI = 1 Gbps and L=1000 bytes for the two cases Bw 2 = 10Mbps and BW 2 = 100 Mbps о d) ls pasket pair dispersion a good indicator of the bottleneck in the between Alice and Bob? What factors affect the accuracy of the method 2 network path may
