Abstract

Conformément à des modes de réalisation, la présente invention concerne un procédé, un dispositif et un système de sauvegarde de serveur multimédia. Le procédé consiste : à détecter si chacun de multiples serveurs multimédias qui prennent en charge des conférences multimédias fonctionne normalement ou non; lorsqu'il est détecté qu'un premier serveur multimédia ne peut pas fonctionner normalement, à distribuer la conférence multimédia prise en charge par le premier serveur multimédia à un ou à plusieurs seconds serveurs multimédias qui peuvent fonctionner normalement; à récupérer la conférence multimédia prise en charge par le premier serveur multimédia sur le ou les seconds serveurs multimédias qui peuvent fonctionner normalement; à donner l'instruction à un terminal de conférence de changer l'adresse de réception et le port de réception du serveur multimédia en adresses de réception et en ports de réception du ou des seconds serveurs multimédias, et à appeler le terminal de conférence à rejoindre de nouveau la conférence multimédia. L'invention concerne également un support de stockage informatique.
