Create a protocol that will solve the problems you saw with Protocol 1 by doing some error-checking. The sender should be able to construct a single multi-packet message that is sent at once. Afterwards they can keep communicating to fix any errors in the transmission. Things to consider: How will the receiver know the order of the packets or if any are missing?
How will the receiver request missing packets and what will the sender do in response?
How will both sender and receiver know the full message arrived successfully?
Write the details of your protocol in the space below or the back of this sheet.
