Title (EN) IDENTIFICATION AND RE-TRANSMISSION OF MISSING PARTS
(FR) IDENTIFICATION ET RETRANSMISSION DE PARTIES TRONQUEES
Abstract:
(EN) The invention relates to a method for file delivery in a system capable of one-to-many transmission, the method comprising transferring one or more data blocks from a sender to at least one receiver, identifying a data block expected to be received but not received at all or incorrectly received at the receiver, and taking action to re-transmit said data block. In the method, said identification is performed on the basis of a block number, an encoding identifier and certain other identification information.
(FR) Cette invention concerne un procédé de distribution de fichiers dans un système pouvant effectuer une à plusieurs transmissions. Le procédé consiste à: transférer un ou plusieurs blocs de données d'un expéditeur à au moins un destinataire; identifier un bloc de données attendu mais pas reçu du tout ou reçu de manière inappropriée par le destinataire; et entreprendre la retransmission du bloc de données. Pour mettre en oeuvre le procédé de l'invention, cette identification se fonde sur un nombre de blocs, un identificateur de codage et certaines autres informations d'identification.
