Question:

Consider an ARQ algorithm running over a 20-km point-to-point fiber link.

(a) Compute the propagation delay for this link, assuming that the speed of light is 2 × 10⁸ m/s in the fiber.

(b) Suggest a suitable timeout value for the ARQ algorithm to use.

(c) Why might it still be possible for the ARQ algorithm to time out and retransmit a frame, given this timeout value?
