Problems solved by technology

[0005] In a virtualized environment, when the virtual machine and the physical network card send and receive each network data packet, they will use the queue selection algorithm to select the sending queue and the receiving queue. The calculation of the selection algorithm is repeated, and the efficiency of the system operation is low.

Abstract

An embodiment of the invention provides a multiple-queue or device selection method and a computing node. The method includes steps as follows: a selection strategy management unit of the computing node sends a reuse indication message to a first selection unit of the computing node, and the reuse indicating message is used for indicating the first selection unit to reuse a selection parameter which is computed by a second selection unit; the first selection unit acquires the selection parameter according to the reuse indication message; and the first selection unit determines a queue or device which is selected to be used in a first queue or device according to the selection parameter. In the embodiment, the computing node reuses the computed selection parameter, so that unnecessary computation can be reduced, and system performance is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computers, and more specifically, to a method for selecting multiple queues or devices and a computing node. Background technique [0002] Multi-queue network card is a technology that was originally used to solve the quality of service (QoS) problem of network input and output (IO). Later, with the continuous improvement of network IO bandwidth, single-core CPUs cannot fully meet the needs of network cards. Through Support for multi-queue network card drivers. When receiving packets, each queue is bound to different cores through interrupts to meet the packet receiving performance requirements of the network card; when sending packets, by selecting different queues, it can meet load balancing requirements and improve packet sending speed. [0003] With the development of virtualization technology, virtual network cards on virtual machines have also begun to use multi-queue technology. For ex...
