ABSTRACT:
Within a transmitter (101), a quantity of data (201) to be transmitted is parsed into variable length, uniquely identified messages (202), which are in turn parsed into fixed-length, uniquely identified blocks (207-211). Messages are buffered and then transmitted to a receiver (103). Upon reception of a message-received communication by the transmitter (101) corresponding to a particular buffered message, that particular message is unbuffered. Upon reception of a message-partially-received communication by the transmitter (101) corresponding to a particular buffered message, those blocks corresponding to portions of the particular buffered message that were not adequately received (703) are retransmitted.
