Title
(EN) SYSTEM AND METHOD OF MULTICASTING MULTIMEDIA STREAMS
(FR) SYSTÈME ET PROCÉDÉ POUR LA MULTIDIFFUSION DE FLUX MULTIMÉDIAS
Abstract
(EN)
A method and system for multicasting a media stream in a telecommunications network. The system includes a broadcast user broadcasting a media stream. The broadcast user determines the destination addresses of each end user desiring to receive the media stream. The media stream is received by an IP router. Within a classification stage of a data-plane residing in the IP router is a replication filter action which replicates the broadcast media stream. The broadcast media stream is replicated with the exception of the destination address. The replicated media stream is sent to each destination address of the end users, thereby providing a multicast media stream to a plurality of end users without requiring a content server of the broadcast user to send multiple media streams.

L'invention concerne un procédé et un système pour la multidiffusion d'un flux média dans un réseau de télécommunications. Le système comprend un utilisateur de diffusion diffusant un flux média. L'utilisateur de diffusion détermine les adresses de destination de chaque utilisateur final souhaitant recevoir le flux média. Le flux média est reçu par un routeur IP. Dans un étage de classification d'un plan de données résidant dans le routeur IP, s'effectue une procédure de filtre de réplication qui réplique le flux média diffusé. Tout le flux média diffusé est répliqué, à l'exception de l'adresse de destination. Le flux média répliqué est envoyé à chaque adresse de destination des utilisateurs finaux, de sorte qu'un flux média de multidiffusion est fourni à une pluralité d'utilisateurs finaux sans nécessiter qu'un serveur de contenu de l'utilisateur de diffusion envoie plusieurs flux média.
