Show that in the Go-Back-N protocol, the size of the send window must be less than 2 where 'K' is the # of bits for sequence numbers; the size of the receive window is always 1. Use the timeline diagram for K = 5 to show the solution. What would be the relationship between the sender window size an the # of sequence bits in Selective-repeat protocol? Show the timeline diagram for K = 5 to show this relationship
