Abstract
(EN)
Transmit data over multiple communication channels in parallel with forward error correction. An optimized number is determined to partition a data segment of a given size into the optimized number of original packets of the same size, by reducing the cost of transmitting dummy data added to the original packets due to the partition, the data fields added to communication packets to support decoding, and redundant packets that are expected to be transmitted via a plurality of parallel channels before the termination of the transmission, as well as the computation cost that increases as a function of the number of original packets. Copies of packets are generated by distributing the original packets to the copies as initial packets and generating each subsequent channel-encoded packet by rejecting useless channel-encoded packets in view of packets assumed to have been received prior to the transmission of the subsequent channel-encoded packet.

La présente invention concerne la transmission de données sur de multiples canaux de communication en parallèle avec une correction d'erreur sans voie de retour. Un nombre optimisé est déterminé pour diviser un segment de données d'une taille donnée en nombre optimisé de paquets d'origine de même taille, en réduisant le coût de transmission de données factices ajoutées aux paquets d'origine en raison de la partition, les champs de données ajoutés aux paquets de communication pour prendre en charge le décodage, et des paquets redondants qui sont supposés être transmis par l'intermédiaire d'une pluralité de canaux parallèles avant la fin de la transmission, ainsi que le coût de calcul qui augmente en fonction du nombre de paquets d'origine. Des copies de paquets sont générées en distribuant des paquets d'origine aux copies en tant que paquets initiaux et en générant chaque paquet codé par canal suivant en rejetant les paquets codés par canal inutiles en vue de paquets supposés avoir été reçus avant la transmission du paquet codé par canal suivant.
