CA 2466196

A hierachy multicasting system (100) includes multiple clients coupled together in a tree structure (102) through a routing process (300). Data is transmitted from a data source (101) to a root node (112) of the tree structure (102). The root node (112) uses its up-link capacity to reflect the data to its children (122, 124). Through various filtering steps, the routing process (300) optimizes the tree structure (102) for efficiency and realibility. In addition, users (612, 622) behind different firewalls (610, 620) may communicate with each other. Therefore, they can be connected in the same hierachy multicasting tree structure (600).

L'invention concerne un système de multidiffusion hiérarchique (100) comprenant plusieurs clients couplés dans une structure arborescente (102) par le biais d'un processus de routage (300). Des données sont transmises d'une source de données (101) à un noeud racine (112) de la structure arborescente (102). Ledit noeud (112) permet d'utiliser sa capacité de liaison montante pour réfléchir les données à ses descendants (112, 124). Au cours de diverses étapes de filtrage, le procédé de routage (300) permet d'optimiser la structure arborescente (102), de manière à apporter une certaine efficacité et une certaine fiabilité. En outre, des utilisateurs (612, 622) se trouvant derrière différents pare-feu (610, 620) peuvent communiquer entre eux. Ainsi, ils peuvent être connectés dans la même structure arborescente de multidiffusion hiérarchique (600).
