PACKET TRANSMISSION/RECEPTION APPARATUS AND METHOD USING FORWARD ERROR CORRECTION SCHEME

摘要

A packet transmission/reception apparatus and method is provided. The packet transmission method of the present invention includes acquiring a source payload including partial source symbols from a source block, generating a source packet including the source payload and an identifier (ID) of the source payload, generating a repair packet including a repair payload corresponding to the source payload and an ID of the repair payload, generating a Forward Error Correction (FEC) packet block including the source and repair packets, and transmitting the FEC packet block. The source payload ID includes a source payload sequence number incrementing by 1 per source packet. The packet transmission/reception method of the present invention is advantageous in improving error correction capability and network resource utilization efficiency.

1. A packet transmission method comprising:
identifying a mode of source packet block generation; generating a source packet block that includes at least one source packet, a source packet including a source payload and a source payload identifier (ID) of the source payload; generating a repair packet block that includes at least one repair packet, a repair packet including a repair payload corresponding to at least one source payload and a repair payload ID of the repair payload; and transmitting the repair packet block, and wherein the source payload ID includes a source payload sequence number that starts from an arbitrary value and is initialized to 0 after reaching a maximum value, and wherein the mode of source packet block generation provides information on a size of the source payload.
