Title (EN) TRANSFERRING PACKETS BETWEEN VIRTUAL MACHINES VIA A DIRECT MEMORY ACCESS DEVICE
(FR) TRANSFERT DE PAQUETS ENTRE DES MACHINES VIRTUELLES PAR L'INTERMÉDIAIRE D'UN DISPOSITIF D'ACCÈS DIRECT À LA MÉMOIRE
Abstract:
(EN) An example computer system for transferring a packet includes a hypervisor to run a first virtual machine and a second virtual machine. The computer system also includes a first memory address space associated with the first virtual machine to store the packet. The computer system further includes a second memory address space associated with the second virtual machine to receive and store the packet. The computer system also includes a virtual switch coupled to the first virtual machine and the second virtual machine to detect that the packet is to be sent from the first virtual machine to the second virtual machine. The computer system further includes a direct memory access device to copy the packet from the first memory address space to the second memory address space via the direct memory access device.
(FR) Selon la présente invention, un exemple de système informatique pour transférer un paquet comprend un hyperviseur afin de faire fonctionner une première machine virtuelle et une seconde machine virtuelle. Le système informatique comprend également un premier espace d'adresse de mémoire associé à la première machine virtuelle afin de stocker le paquet. Le système informatique comprend en outre un second espace d'adresse de mémoire associé à la seconde machine virtuelle afin de recevoir et stocker le paquet. Le système informatique comprend également un commutateur virtuel couplé à la première machine virtuelle et à la seconde machine virtuelle afin de détecter que le paquet doit être envoyé de la première machine virtuelle à la seconde machine virtuelle. Le système informatique comprend en outre un dispositif d'accès direct à la mémoire afin de copier le paquet du premier espace d'adresse mémoire au second espace d'adresse mémoire par l'intermédiaire du dispositif d'accès direct à la mémoire.
