Reliable Delivery of Data
ADSP guarantees that data bytes are delivered in the same order as they were sent and that they are free of duplicates. It ensures that all data sent is delivered to the remote connection end's receive buffer. To accomplish this, ADSP associates a sequence number with each byte that it sends. ADSP discards any out-of-sequence data or any duplicates that are delivered. ADSP uses the sequence numbers to ensure that all of the data that one end sends is received by the other end. If data is lost, ADSP retransmits it. ADSP
can send the data again because the data remains in the sending connection end's send queue until the remote end actually receives a copy of it. For more information about how ADSP delivers data, see Inside AppleTalk, second edition.
