Imagine that you are writing the data linksoftware for a line used to send data to you, but not from you. The other end uses HDLC, with a 3-bit sequence number and window size of seven frames. You would like to buffer as many out of sequence frames as possible to enhance efficiency, but you are not allowed to modify the software on the sending side. Is it possible to have a receiver window greater than one and still guarantee that the protocol will never fail? If so, what is the largest window that can be safely used?
