Solution to Assignment 1 1. transmission delay = L/R where L = length of packet in bits, R = rate For 1Gbps link, transmission delay = 100/1000000000 = 100 ns For 100Mbps link, transmission delay = 100/100000000 = 1 μ s 2. a) transmission delay for 10 cars = 12 * 10 = 120 secs = 2 min. t1 = transmission delay at booth1 = 2 min. t2 = propagation delay from booth 1 to booth 2 = 100/100 = 1 hr.= 60 mins t3 = transmission delay at booth 2 = 2 min. t4 = propagation delay from booth 2 to booth 3 = 100/100 = 1 hr. = 60 mins. end to end delay = t1 + t2 + t3 + t4 = 2 + 60 + 2 + 60 =124 mins. = 2 hrs and 4mins. b) transmission delay for 7 cars = 12 * 7 = 84 secs t1 = transmission delay at booth1 = 84 sec. t2 = propagation delay from booth 1 to booth 2 = 100/100 = 1 hr. = 3600 sec t3 = transmission delay at booth 2 = 84 sec. t4 = propagation delay from booth 2 to booth 3 = 100/100 = 1 hr. = 3600 sec end to end delay = t1 + t2 + t3 + t4 = 84 + 3600 + 84 + 3600 = 7368 sec = 2 hrs 2 mins and 48 secs
