Question: Transmission delay and propagation delay Consider two hosts, A and B, directly connected by a link of 2500 Km, propagation speed 2.5*108 m/s, and transmission

Transmission delay and propagation delay Consider two hosts, A and B, directly connected by a link of 2500 Km, propagation speed 2.5*108 m/s, and transmission rate 8 Mbps. Assume zero queuing delay.

a) How long does it take to move a packet of length 1000 bytes from one A to B?

b) Assume the transmission time of the packet is dtrans and the propagation delay dprop. Suppose that host A begins to transmit a packet at time t=0. At time t= dtrans where is the last bit of the packet?

c) Suppose dprop is greater than dtrans. At time t= dtrans, where is the first bit of the packet?

d) Suppose dprop is less than dtrans. At time t= dtrans, where is the first bit of the packet?

e) You want to urgently deliver 40 terabytes of data from Buffalo to San Francisco. You have available a 100 Mbps dedicated link for the data transfer. Would you transmit the data over this link or use FedEx overnight delivery instead? Explain (write down any assumptions).
