Q21. Refer to Fig. 1 -Let us assume we send a single packet of size L bits from h1 to h2. The two intermediate nodes N1 and N2 each have a processing delay of Pd - There is no other traffic in the network Signal propagates at speed s Distance d3, rate R3 Distance d1, rate R1 N1 N2 h1 h2 Distance d2, rate R2 Figure 1 Give the mathematical expression for the total packet delay, as a function of Pd, L, R1, R2, R3, d1, d2, d3 and Show your calculations. Type: E 022. Refer to the same figure. Use the expression from the previous question to come up with a numeric answer when: L 10000 bits, Pd 0.5 msec, R1 1 Gbps, R2 2 Mbps, R3 10 Mbps, d1 - 5 km, d2 10 km, d3 10 km, s- 2.5 x 10 8 m/sec. What type of delay is the main contributor to the total delay? What is the numeric value of the total delay when: L 1000 bits, Pd 0.5 msec, R1 10 Mbps, R2 2 Mbps, R3 10 Mbps, d1 500 km, d2 1000 km, d3- 1000 km, S 2.5 x10 m/sec.
