(FR) PROCÉDÉ, APPAREIL ET SUPPORT DE STOCKAGE LISIBLE PAR ORDINATEUR POUR OPTIMISATION DE RÉSEAU PERMETTANT D'ACCÉDER À UN SERVICE EN NUAGE À PARTIR D'UN RÉSEAU LOCAL
Abstract
(EN)
Apparatus and methods include receiving a first packet, the first packet including a first source Internet protocol (IP) address and a first destination IP address; adding a first outer header to the first packet to generate an encapsulated packet, the first outer header including a second source IP address and a second destination IP address; forwarding the encapsulated packet to a Server Load Balancer (SLB) associated with the second destination IP address; receiving a response packet from a front end server having a front end server private IP address; and saving the front end server private IP address to bypass the SLB.
(FR)
L'invention concerne un appareil et des procédés consistant à : recevoir un premier paquet, le premier paquet comprenant une première adresse IP (Internet Protocol) et une première adresse IP de destination ; ajouter un premier en-tête externe au premier paquet afin de générer un paquet encapsulé, le premier en-tête externe comprenant une seconde adresse IP source et une seconde adresse IP de destination ; transférer le paquet encapsulé à un équilibreur de charge de serveur (SLB) associé à la seconde adresse IP de destination ; recevoir un paquet de réponse d'un serveur frontal ayant une adresse IP privée de serveur frontal ; et enregistrer l'adresse IP privée de serveur frontal pour contourner le SLB.
