Method and system for transmitting data based on Virtio port

Abstract

The invention discloses a method and a system for transmitting data based on a Virtio port, and belongs to the technical field of virtualization. The method comprises the following steps: when a Vswitch receives a first data content sent by a physical network card, the Vswitch determines a first Vswitch logic port for sending the first data content, and adds a port identifier of the first Vswitchlogic port to the first data content; the Vswitch sends the first data content to a Vrouter through the first Vswitch logic port and a Virtio port shared between the Vswitch and the Vrouter, and the Vswitch sends the second data content to the Vrouter through the second Vswitch logic port and the Virtio port shared between the Vswitch and the Vrouter; the Vrouter receives the first data content through a first Vrouter logic port uniquely corresponding to the port identifier of the first Vswitch logic port, and sends the first data content to a first virtual network card corresponding to the first Vrouter logic port. According to the method disclosed in the invention, data transmission performance can be improved.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to a method and system for transmitting data based on a Virtio port. Background technique [0002] The virtualized network includes components such as Vrouter (virtual router) and Vswitch (virtual switch). Virtio technology is a paravirtualized device abstract interface specification. Virtio ports are usually used to transmit data between Vrouter and Vswitch. Among them, the Virtio port on the Vswitch side can be called Virtio_host port, and the Virtio port on the Vrouter side The port may be referred to as a Virtio_user port. [0003] Vswitch can be connected to multiple Vrouters, and each Vrouter can create a Virtio_user port for the virtual network card of the tenant network it manages. If a tenant network is configured with multiple virtual network cards, the Vrouter needs to be created for each virtual network card of the tenant network. A Virtio_user port, correspondi...

Problems solved by technology

[0005] Each Virtio port needs to occupy a certain amount of memory resources. When many Virtio ports are created, a large amount of memory resources will be occupied, which will have a great impact on data transmission, resulting in low transmission performance.
