Question: Consider a sliding window ARQ protocol running over a 80-km point-to-point fiber link. The data rate is 100 Mbps and the ACK packet size is

Consider a sliding window ARQ protocol running over a 80-km point-to-point fiber link. The data rate is 100 Mbps and the ACK packet size is 40 bytes. --------- What is the one-way propagation delay for this link, assuming that the speed of light is 2 10⁸ m/s in the fiber ? -------- What is a feasible timeout value for the protocol? Explain your choice. -------- Explain why it is still possible for the protocol to time out at the transmitter and retransmit a frame, given this timeout value?
