Abstract

L'invention appartient au domaine technique de l'Internet. Elle concerne un procédé et un appareil de transfert de paquet. Le procédé consiste à recevoir un paquet envoyé par la couche réseau et à déterminer si le paquet est le premier paquetage d'un flux de paquets. Si le paquet est le premier paquetage du flux de paquets, le paquet est transféré à la couche application. Si le paquet n'est pas le premier paquetage du flux de paquets, le procédé détermine si le paquet est le premier paquetage d'un message dans le flux de paquets. Si le paquet est le premier paquetage du message dans le flux de paquets, le paquet est transféré à la couche application. Enfin, si le paquet n'est pas le premier paquetage du message dans le flux de paquets, le paquet est transféré à la couche réseau. La présente invention permet de déterminer si chaque paquet d'un flux de paquets est le premier paquetage d'un message dans le flux de paquets. Si oui, le paquet est transféré à la couche application, pour résolution. Sinon, chaque paquet est transféré directement à un réseau. Le transfert d'un grand nombre de paquets ne devant pas être résolus, à un réseau, ne permet pas seulement d'améliorer l'efficacité de transfert d'un paquet. Il permet également de réduire la charge de la couche application qui résout le paquet.
