It is often the case that a “different” puzzle presents an opportunity for a young scientist to say “Oh, I can solve this problem because it’s different”. Well, sure…but is it simpler, or simply different?
The question begs in a discussion of using reliable link layers in wireless to solve the problem of retransmissions and poor QOS. The problem is that artifact of retransmission distorts the use of the medium, because too many retransmits / congestion events occur, biasing the statistics and becoming unfair. The solution for the wireless approach is to use the same thing that causes artifacts of noise as an architectural solution.
