Problems solved by technology

It can be seen that when forwarding packets between local virtual machines in the existing way, it is necessary to perform a copy operation on buffer resources, that is, a memory copy operation is required, so that the efficiency of packet forwarding between local virtual machines is low. And cause the network card bandwidth resources to consume more

Abstract

The embodiment of the invention discloses a method and a device for allocating a single root-input / output virtualization (SR-IOV) network card buffering resource, which relates to the field of a communication system, can avoid the copy operation of the buffering resource in a message forwarding process among local virtualization machines, can improve the message forwarding efficiency among the local virtualization machines, and also can reduce the waste of the network card bandwidth resource. The method comprises the following steps of firstly acquiring the buffering resource from a preset public buffering resource pool, configuring the buffering resource into a transmitting buffering queue of a first virtualization machine, picking the buffering resource from the transmission buffering queue if a target address of a message is a local second virtualization machine, configuring the buffering resource into the receiving buffering queue of the second virtualization machine, and enabling the second virtualization machine to receive the message.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a method and device for allocating buffer resources of an SR-IOV network card. Background technique [0002] With the continuous development of science and technology, the application range of virtualization technology is also becoming wider and wider. Wherein, the SR-IOV (Single-RootI / OVirtualization, virtualization technology) network card is a network card supporting the virtualization technology. The SR-IOV network card can allocate buffer resources for multiple VFs (Virtual Functioning, virtual functions) corresponding to a VM (Virtual Manufacturing, virtual machine) according to a preset configuration scheme, so that messages can be sent and received between different virtual machines. [0003] When the existing SR-IOV network card implements message forwarding between local virtual machines, it first needs to copy the send buffer resource of the message from the send ...
