Abstract

Procédé d'attribution d'une adresse IP de multidiffusion à partir d'un nom d'espace (301) de longueur en bits variable et d'un nom de commande (302) de longueur en bits variable, dans un réseau de télécommunications IP utilisant UDP, comprenant les étapes suivantes : Hacher(306) sur une première longueur fixe en bits le nom d'espace pour obtenir un nom d'espace haché Hacher(306) sur une seconde longueur fixe en bits le nom de commande pour obtenir un nom de commande haché Former un identificateur de groupe haché (303) d'une troisième longueur fixe en bits, par juxtaposition (308) des bits du nom d'espace haché et du nom de commande haché, la troisième longueur fixe en bits de l'identificateur de groupe haché étant la somme de la première longueur fixe en bits et de la seconde longueur fixe en bits, Former une adresse IP(305) par juxtaposition (308) des bits d'un préfixe de multidiffusion (304) et de l'identificateur de groupe haché(303).Method for assigning a multicast IP address from a variable bit length space name (301) and a variable bit length control name (302), in an IP telecommunications network using UDP, comprising the following steps: Hash (306) on a first fixed length in bits the space name to obtain a hashed space name Hash (306) on a second fixed length in bits the command name to obtain a hashed command name Form a hashed group identifier (303) of a third fixed length in bits, by juxtaposition (308) of the hash space name and hashed command name bits, the third fixed length in bits of l hashed group identifier being the sum of the first fixed length in bits and the second fixed length in bits, Form an IP address (305) by juxtaposition (308) of the bits of a multicast prefix (304) and the hashed group identifier (303).
