P10. Consider a packet of length L 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. Let d;, s;, and R; denote the length, propagation speed, and the transmission rate of link i, for i = 1, 2, 3. The packet switch delays each packet by dproc: Assuming no queuing delays, in terms of d;, s;, R, (i = 1, 2, 3), and L, what is the total end-to-end delay for the packet? Sup- pose now the packet is 1,500 bytes, the propagation speed on all three links is 2.5 · 10°m/s, the transmission rates of all three links are 2.5 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay?
