Abstract

La présente invention concerne un procédé de collaboration informatique et un appareil associé. Le procédé comprend les étapes suivantes : un second dispositif de réseau indique directement, à un premier dispositif de réseau, un mode de collaboration du premier dispositif de réseau, tel que le traitement, ou le transfert, ou le traitement et le transfert de données informatiques ; ou le second dispositif de réseau envoie des premières informations d'indication à un dispositif terminal, les premières informations d'indication étant utilisées pour indiquer le mode de collaboration du premier dispositif de réseau, de telle sorte que, lors de l'envoi de données informatiques au premier dispositif de réseau, le dispositif terminal indique le mode de collaboration au premier dispositif de réseau en transportant les premières informations d'indication dans l'en-tête d'un paquet de données transportant les données informatiques. Ainsi, une commande flexible du mode de collaboration du premier dispositif de réseau est mise en œuvre, de telle sorte que le premier dispositif de réseau peut effectuer une opération raisonnable sur les données informatiques reçues.
