Question: Consider two hosts, A and B that are connected by a fiber optic transmission link of 6 Mbps with propagation speed of 12x108 m/s. Packet

Consider two hosts, A and B that are connected by a fiber optic transmission link of 6 Mbps with propagation speed of 12x108 m/s. Packet length is 1.5 Kb (Kilobits) and link length is 300Km.

a. What is the propagation delay from A to B - the amount of time from when the first bit of the packet is transmitted at A, until it is received at B?

b. What is the transmission time of the packet at A (the time from when the first bit of the packet is sent into the wire, and the time at which the last bit is sent into the wire)?

c. How long must a packet be so that the receiver is receiving the first bit at the same time that the sender is sending the last bit?
