Title
(EN) METHOD OF FORWARDING IN A MULTI-HOP ACCESS NETWORK
(FR) PROCEDE D'EXPEDITION DANS UN RESEAU D'ACCES A SAUTS MULTIPLES
Abstract
(EN)
Method of forwarding executed by a node of a multi-hop access network, said node comprising a plurality of output tunnels, the method of forwarding comprising; a step of receiving a data packet of a multimedia stream, a step of processing said data packet by a scheduler, and - after said step of processing, a step of determining at least one output tunnel from among said plurality of output tunnels, to which to transmit said data packet, by consulting a forwarding data base, characterized in that it comprises, before said processing step, a step of associating, with the data packet, at least one output tunnel and a first number representative of a quality of transmission with which the multimedia stream must be transmitted to said output tunnel, said forwarding data base comprising a record per output tunnel of said plurality of output tunnels, each record containing an aggregation identity (IDag)representing a product of prime numbers, each of said prime numbers representing a quality of transmission with which a multimedia stream must be transmitted to the output tunnel of said record, said step of determining comprising, for each record of said forwarding data base; a step (F72) of testing a condition representing the divisibility of the product represented by the identity of aggregation of the record by said at least one prime number associated with said data packet during the associating step, and when said condition is satisfied, a step (F74) of transmitting said data packet to the output tunnel of said record.

Procédé d'expédition exécuté par un nœud d'un réseau d'accès à sauts multiples, ledit nœud comprenant une pluralité de tunnels de sortie, le procédé d'expédition comprenant; une étape de réception d'un paquet de données d'un flux multimédia, une étape de traitement dudit paquet de données par un ordonnanceur, et - après ladite étape de traitement, une étape de détermination d'au moins un tunnel de sortie parmi ladite pluralité de tunnels de sortie, vers laquelle transmettre ledit paquet de données, en consultant une base de données d'expédition, caractérisé en ce qu'il comprend, avant ladite étape de traitement, une étape d'association, avec le paquet de données, d'au moins un tunnel de sortie et d'un nombre premier représentatif d'une qualité de transmission avec laquelle le flux multimédia doit être transmis vers ledit tunnel de sortie, ladite base de données d'expédition comprenant un enregistrement par tunnel de sortie de ladite pluralité de tunnels de sortie, chaque enregistrement contenant une identité d'agrégation (IDag) représentant un produit de nombres premiers, chacun desdits nombres premiers représentant une qualité de transmission avec laquelle un flux multimédia doit être transmis vers le tunnel de sortie dudit enregistrement, ladite étape de détermination comprenant, pour chaque enregistrement de ladite base de données d'expédition; une étape (F72) de test d'une condition représentant la divisibilité du produit représenté par l'identité d'agrégation de l'enregistrement par ledit au moins un nombre premier associé audit paquet de donnée lors de l'étape d'association, et lorsque ladite condition est vérifiée, une étape (F74) de transmission dudit paquet de données vers le tunnel de sortie dudit enregistrement.
