Method and device for sending data package

Abstract

The embodiment of the invention provides a method and device for sending a data package, and relates to the field of communication. The method and device for sending the data package are used for controlling the speed of sending the data package to a target device by a virtual switch. The method comprises the steps that the visual switch establishes a first virtual network interface card corresponding to a first visual machine in a physical machine, the data package is sent to the first visual network interface card after the data package which is sent through a corresponding second visual network interface card by the first visual machine is received, wherein the first visual network interface card is equipped with a first data package sending rule, the visual switch receives the data package which is sent by the first visual network interface card according to a first sending speed, and the data package is sent to the target device according to the first sending speed. The method and device for sending the data package are used for sending the data package to the target device by the visual machine.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending data packets. Background technique [0002] In server virtualization technology, when a virtual machine configured in a physical machine sends data packets, it needs to send the data packets to the destination device (such as a physical network card or other virtual machines configured in the physical machine) through a virtual switch. During the process of sending packets, it will occupy physical resources (such as bandwidth resources of the physical network card, computing resources of the CPU, etc.). The normal operation of the device (such as other virtual machines configured in the physical machine), therefore, it is necessary to control the data packet sending rate of the virtual machine. [0003] In an existing method for controlling the data packet sending rate of a virtual machine, a data packet sending rule is configured in the physical...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the rate at which the virtual switch sends data packets to the destination device is uncontrollable. If the destination device is another virtual machine configured in the physical machine, the virtual switch sends the data packet to other virtual machines configured in the physical machine. There is no need to go through the physical network card in the process of the machine, so the control of the data packet sending rate cannot be realized
