Consider a communication session between two computer nodes through a network of interconnected switching/routing nodes. Typically, the data link provides reliability be performing automatic repeat request (i.e. ARQ or retransmission) for erroneous frames on a hop-by-hop basis. If is desired to design a network that utilizes reliable physical links (such as fiber optics) where bit error rates are infinitesimal, would it be wise to maintain the retransmissions function on a hop-by-hop basis? Explain and justify your answer pointing out example technologies and implemented standards.
