Title (EN) METHODS AND SYSTEMS TO OFFLOAD OVERLAY NETWORK PACKET ENCAPSULATION TO HARDWARE
(FR) PROCÉDÉS ET SYSTÈMES DE DÉLESTAGE DE PAQUETS ENCAPSULÉS D'UN RÉSEAU SUPERPOSÉ À UN MATÉRIEL
Abstract:
(EN) A method for offloading packet encapsulation for an overlay network is provided. The method, at a virtualization software of a host, sends a mapping table of the overlay network to a physical network interface controller (NTC) associated with the host. The mapping table maps the identification of each of a set of virtual machine (VM) of a tenant on the host to an identification of a tunnel on the overlay network. The method, at the virtualization software, receives a packet from a VM of the tenant. The method sends the packet to the physical NIC. The method, at the physical NIC, encapsulates the packet for transmission over the overlay network by using the mapping table. The method of claim also tags the packet by the virtualization software as a packet that requires encapsulation for transmission in the overlay network prior to sending the packet to the physical NIC.
(FR) L'invention concerne un procédé de délestage de paquets encapsulés d'un réseau superposé. Au logiciel de virtualisation d'un hôte, le procédé envoie une table de mappage du réseau superposé à un contrôleur d'interface réseau physique (NIC) associé à l'hôte. La table de mappage mappe l'identification de chacune d'un ensemble de machines virtuelles (VM) d'un locataire sur l'hôte par rapport à une identification d'un tunnel sur le réseau superposé. Au logiciel de virtualisation, le procédé reçoit un paquet, d'une VM du locataire. Le procédé envoie le paquet au NIC physique. Au NIC physique, le procédé encapsule le paquet en vue de la transmission sur le réseau superposé, au moyen de la table de mappage. Le procédé selon l'invention étiquette également le paquet avec le logiciel de virtualisation en tant qu'un paquet nécessitant une encapsulation en vue de la transmission sur le réseau superposé, avant d'envoyer le paquet au NIC physique.
