US 2015/0319250 A1 · TECHNOLOGIES FOR ACCELERATING NETWORK VIRTUALIZATION

Abstract

Technologies for accelerated network virtualization include executing packet processing functions by a network virtualizer established in a provider partition of a computing device and offloading packet movement functions to a network interface controller of the computing device. In the illustrative embodiments, the network interface controller includes one or more tenant-facing ports, a provider-facing port, and an external network-facing port, which are used by the network interface controller to receive, send, and pass packets from, to, and between the various partitions of the computing device. To transmit a packet, the network virtualizer generates a provider header, and either the network virtualizer or the network interface controller encapsulates a packet received from the tenant partition with the provider header. To receive a packet, either the network virtualizer or the network interface controller strips a provider header from the received packet.

Claims25

Dependent claims

A computing device for accelerated network virtualization, the computing device comprising:

a host established on a tenant partition of the computing device;
a network virtualizer established in a provider partition of the computing device different from the tenant partition, the network virtualizer to generate a provider header;
and
a network interface controller having a first port to facilitate communication with the host of the tenant partition, a second port to facilitate communication with network virtualizer of the provider partition, and a third port to facilitate communication with a network external to the computing device,
wherein the network interface controller includes a packet handler module to pass packets between the tenant partition and the provider partition and transmit packets encapsulated with the provider header across the network via the third port.

2 more elements

One or more machine-readable storage media comprising a plurality of instructions stored thereon that, in response to execution, cause a computing device to:

generate, by a host of a tenant partition of a computing device, a packet for transmission from the computing device;
generate, by a network virtualizer established in a provider partition of the computing device different from the tenant partition, a provider header for the packet;
receive, by a first port of a network interface controller of the computing device, the packet from the host of the tenant partition;
communicate, by a second port of the network interface controller, with the network virtualizer to encapsulate the packet with the provide header;
and
transmit, by a third port of the network interface controller, the packet encapsulated with the provider header across a network external to the computing device.
