Abstract

L'invention concerne un procédé, un appareil et un système pour traiter un paquet, lesquels peuvent améliorer l'efficacité de transfert de paquet. Un dispositif de commande détermine un chemin de transmission d'un service cible, le chemin de transmission comprenant au moins deux nœuds de traitement ; le dispositif de commande génère respectivement une politique de traitement pour chaque nœud de traitement sur le chemin de transmission, chaque politique de traitement étant utilisée pour indiquer le saut suivant du nœud de traitement correspondant dans le chemin de transmission ; le dispositif de commande envoie, à chaque nœud de traitement, une relation de mappage entre une politique de traitement générée pour le nœud de traitement et une identification de service du service cible, la relation de mappage étant utilisée pour permettre à un nœud de traitement qui reçoit un paquet transportant l'identification de service du service cible de déterminer la politique de traitement correspondante sur la base de la relation de mappage reçue par le nœud de traitement, et de traiter le paquet selon la politique de traitement, et l'identification de service étant attribuée au service cible par le dispositif de commande et étant utilisée pour identifier de manière unique le service cible.
