3) Show, through a detailed scenario/example, why GBN protocol would fail in case the sender's window size exceeds 2-1, where k is the number of frame bits for the sequence number. Considering that the window size is set to what it is expected to be. Is there any possibility that GBN could produce the same performance obtained by the Unrestricted Protocol? If no, explain clearly why this is infeasible. If so, explain clearly how, or under what conditions, GBN could produce the same performance of the Unrestricted Protocol. 3) Show, through a detailed scenario/example, why GBN protocol would fail in case the sender's window size exceeds 2-1, where k is the number of frame bits for the sequence number.
