Homework Question 23. 1. Consider an ARQ algorithm running over a 40-km point-to-point fiber optic link. (10 points) (a) Compute the propagation delay for this link, assuming that the speed of light is 2 x 108 meters per second in the fiber. (b) Suggest a suitable timeout value for the ARQ algorithm to use. (Assume that transmission time for data frames and returning ACKs is insignificant, compared to link propagation delay.) (c) Why might it still be possible for the ARQ algorithm to time out and retransmit a frame, given this timeout value
