Embodiment 1

[0037] figure 1 It is a flow chart of a virtual switching device data forwarding method provided in Embodiment 1 of the present invention, and the method includes the following steps:

[0038] Step S11: Using the vhost interface to receive the first network data transmitted by the virtual terminal, and transmit the first network data to the network bridge.

[0039] In the embodiment of the present invention, the virtual switching device, that is, a virtual network switching device based on ovs (ovs, open vswitch, open virtual switching standard), utilizes a virtual platform to form a switch component through software. Wherein, the virtual switching device can be set in a server, and a server can have dozens or even hundreds of virtual switching devices, and the number of ports of the virtual switching device can be flexibly set by the device manager, for example, can use The server performs software simulation to generate 200 virtual switching devices, and the ports of each v...

Embodiment 2

[0048] figure 2 It is a flow chart of a virtual switching device data forwarding method provided in Embodiment 2 of the present invention, and the method includes the following steps:

[0049] Step S21: Using the vhost interface to receive the first network data transmitted by the virtual terminal, and transmit the first network data to the network bridge.

[0050] This step is consistent with the above step S11, and will not be repeated here.

[0051] Step S22: Encapsulate the first network data with a preset protocol in the network bridge according to the pre-established encapsulation flow table, generate a forwarding data packet, and transmit it to the dpdk port.

[0052] This step is consistent with the above step S12, and will not be repeated here.

[0053] Step S23: Send the forwarded data packet to the destination terminal through the network card on the dpdk port.

[0054] This step is consistent with the above step S13, and will not be repeated here.

Abstract

The invention provides a method and an apparatus for forwarding data of a virtual switching device, and a computer device. The method for forwarding the data of the virtual switching device comprisesthe steps of: receiving, by using a vhost interface, first network data transmitted by a virtual terminal, and transmitting the first network data to a network bridge; performing encapsulation of a preset protocol on the first network data in the network bridge according to a preliminarily established encapsulation flow table to generate a forwarding data packet, and transmitting the forwarding data packet to a Data Plane Development Kit (dpdk) port; and sending the forwarding data packet to a target terminal via a network card at the dpdk port. According to the method for forwarding the dataof the virtual switching device provided by the invention, one network bridge in a one-off data forwarding process can be reduced and the data copies of a memory of a one-off virtual switching deviceare reduced; and therefore, the forwarding performance of the virtual switching device is improved.

Description

technical field [0001] The present invention relates to the field of virtual networks, in particular to a virtual switching device data forwarding method, device, computer equipment and computer storage medium. Background technique [0002] In the current NFV network (NFV, Network Function Virtualization, network function virtualization), it is necessary to construct a logical network on the physical network. [0003] The logical network includes a virtual switching device, and the network data of the virtual terminal is forwarded by the virtual network device. The existing virtual switching device involves multiple forwarding in the data processing process, and the data will be used when forwarding the data. copy, thereby reducing the forwarding performance of the virtual switching device. Contents of the invention [0004] In view of the above problems, the present invention provides a virtual switching device data forwarding method, device, computer equipment and compu...
