Suppose N 4 and the reliable data transfer protocol is Selective Repeat. Assume that che sequence number space is set appropriately, i.e., it is at least 2N 8. Suppose at time t, the cvbase is 5 at the receiver. True or false: the receiver can receive a packet of sequence number 1 at time t, and in that case, it should send ack1. Briefly justify your answer.
