Abstract

La présente invention concerne un procédé pour extension parallèle de la technologie de direct pour multimédia en diffusion en flux en P2P. En l'occurrence, une fois que la source de publication multimédia à diffusion en flux a enregistré l'information de programme pour une pluralité de serveurs tampons multimédia en diffusion en flux, chacun en ce qui le concerne, la source de publication multimédia à diffusion en flux envoie périodiquement les données du multimédia à diffusion en flux aux serveurs tampons multimédia en diffusion en flux, et une fois que le serveur tampon multimédia en diffusion en flux s'est connecté au serveur de gestion principal, le serveur tampon multimédia en diffusion en flux enregistre la liste d'information multimédia en diffusion en flux; le serveur de gestion principal met en mémoire toute liste de serveurs tampons multimédia en diffusion en flux, et met à jour périodiquement l'information de serveur tampon multimédia en diffusion en flux, le serveur de gestion P2P communique périodiquement avec le serveur de gestion principal, rend compte de l'information de départ du serveur; le client se connecte d'abord au serveur de connexion, conformément à la situation de charge de tous les serveurs courants de gestion P2P, le serveur de connexion sélectionne un serveur de gestion P2P dont les numéros de peuplement ne sont pas pleins et se connecte au serveur de gestion P2P, par l'intermédiaire du serveur de connexion, le client sélectionne le serveur de gestion P2P à petite charge, faisant un ordonnancement entre une pluralité de serveurs de gestion P2P pour extension parallèle, ainsi le problème de l'encombrement du réseau est résolu effectivement.
