| 摘要 |
A retransmission method for use in handshakeless communication consistent with certain embodiments involves transmitting a sequence of packets from a packet source to a packet receiving device, each packet in the sequence of packets having a sequence number associated therewith, said transmitting including retrieving a next packet from a transmission buffer and transmitting said next packet; at the packet receiving device, determining that a packet has not been received by determining that a gap exists in the sequence numbers of received packets; sending a retransmission request from the receiving device to the transmitting device, such retransmission request requesting retransmission of a specified packet whose sequence number is in the gap in sequence numbers; at the packet source, receiving the retransmission request for the specified packet; at the packet source, determining if the specified packet remains available in the transmission buffer; if the specified packet is available in the transmission buffer, retransmitting the specified packet to the receiving device; and if the specified packet is not available in the transmission buffer, ignoring the retransmission request. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
