Le procédé consiste à : établir des relations d'association entre un système de diffusion en direct et au moins deux systèmes de réseau de distribution de contenu (CDN) ; déterminer, d'après des paramètres de fonctionnement actuels de chaque système CDN, des informations d'état de service de chaque système CDN, les informations d'état de service étant utilisées pour représenter les performances de service actuelles d'un système CDN autre qu'un système CDN défaillant ; et déterminer, d'après les informations d'état de service, un système CDN satisfaisant des conditions de service, et commuter le système CDN satisfaisant les conditions de service à un système CDN cible qui fournit actuellement des services au système de diffusion en direct, de sorte à fournir des données de service de diffusion en direct à l'aide du système CDN cible. Le procédé améliore ainsi la qualité d'une diffusion en direct et l'expérience de l'utilisateur.
