Consider a packet of length 1,000 bytes that begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Assume that the propagation speed on all three links is 2.5 x 108 m/s, the lengths of these links are 5,000km 4,000km, and 1000km, respectively. The transmission rates for the three links are 2Mbps, 10Mbps, and 1Mbps, respectively. The switch processing delay is 3msec. What is the end-to-end delay
