- Let di,si, and Ri 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. - Assume no queuing delays in the switches a.Draw a picture and label the components of delay (d,s,R etc.) b.What is the service time in each switch? c. In terms of di,si, and Ri,(i=1,2,3), and L, what is the total end-to-end delay for the packet? d. Now suppose: - the packet length is 1,500 bytes - the propagation speed on all three links is 2.5108m/s - the transmission rates of all three links are 2.5Mbps - the packet switch processing delay is 3 msec - the length of the first link is 5,000km, the length of the second link is 4,000 km, and the length of the last link is 1,000km. Consider a packet of length L that begins at end istem A and travels over three links to a destination end istem. These three links are connected by two packet vitches. - Let di,si, and Ri 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. - Assume no queuing delays in the switches a.Draw a picture and label the components of delay (d,s,R etc.) b.What is the service time in each switch? c.

Discuss. Why or why not? b) Can throughput at the Receiver can be greater than the Sender's transmission rate? Discuss. Why or why not
