Question:

Imagine that you are writing the data link layer software 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 a 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 1, and still guarantee that the protocol will never fail? If so, what is the largest window that can be safely used?
