More Information
Summary:A packet transmission apparatus to transmit a packet limited in arrival deadline through a best-effort network includes a packet automatic retransmission section to control retransmission of an undelivered packet, a forward error correction coding section to add redundant packet to a data packet block, and a redundancy determining section to dynamically determine redundancy of the redundant packet based on observed network state information so that a loss rate after error correction at a receiver achieved by only the retransmission of the undelivered packet satisfies an allowable loss rate after error correction.
