Abstract

Selon l'invention, un dispositif de commande distribue des informations de routage et des informations d'entrée de protocole de résolution d'adresse (ARP) à une machine virtuelle (VM). Les informations de routage indiquent qu'un saut suivant d'un flux à envoyer au réseau externe est une passerelle de réseau externe logique pré-créée, et les informations d'entrée d'ARP comprennent une adresse de contrôle d'accès au support (MAC) de la passerelle de réseau externe logique. Le dispositif de commande distribue une table de flux à un commutateur. La table de flux indique qu'un flux dont l'adresse MAC de destination est l'adresse MAC de la passerelle de réseau externe logique doit être transféré à une passerelle de réseau externe réelle.
