Consider a Go-Back-N sliding window algorithm (1 packet is 250 bytes long) running over a 100km point-to-point fiber link with bandwidth of 100 Mbps.

a. Compute the one-way propagation delay for this link, assuming that the speed of light is 2 x 10⁸ m/s in the fiber. b. Suggest a suitable timeout value for the algorithm to use. List factors you need to consider. c. Suggest N to achieve 100% utilization in this link.
