L'invention concerne un procédé de commande de transmission de données de service de grappe exécuté par un réseau central. Le procédé consiste à : établir une liaison entre des dispositifs de réseau lorsqu'une transmission de données de service de grappe est déclenchée, la transmission de données de service de grappe étant exécutée entre les dispositifs de réseau ; acquérir des identifiants d'adresse des dispositifs de réseau ; et émettre un identifiant d'adresse de destination requis pour la transmission de données de service de grappe aux dispositifs de réseau via la liaison entre les dispositifs de réseau. L'invention concerne en outre un procédé et un appareil de transmission de données de service de grappe, un dispositif de réseau central, et un dispositif de réseau. Comme le procédé et l'appareil de commande de transmission de données de service de grappe susmentionnés, le dispositif de réseau central, et le dispositif de réseau, n'ont pas besoin d'être pourvus d'un nom de point d'accès pour parvenir à une dérivation du réseau central, la mise en œuvre est pratique et facile.
