The receiver window size M is not equal to sender window size N so it must be bidirectional. If it is unidirectional, then the receive window should be 1 for Go-Back-N protocol and N for Selective-Repeat protocol. Then it is very straightforward: the minimum sequence number should be N+M. matt wiley attorney ct
