ABSTRACT:
Mechanisms in which reliable communication is enabled without having to wait for a final acknowledgement message. An upper layer issues a send request. The message is then placed in a send queue. If data in the send queue is less than (or equal to) a predetermined threshold at this stage, the packet is sent, a successful transmission report is returned to the caller, and the data is copied to an internal buffer for use in case transmission was unsuccessful. If the amount of data in the send queue is more than that predetermined threshold, the packets are sent. Subsequently, each time an acknowledgement is received, the determination is repeated until the amount of unacknowledged data in the send queue is less than or equal to the predetermined threshold. Then, the successful transmission report is returned to the caller.
