An information transmission method and device

Abstract

An embodiment of the invention discloses an information transmission method and device and relates to the electronic information technical field. Communication between virtual machines can be controlled by distributing identification, thereby reducing possibility of data leakage of node devices due to communication between the virtual machines. The method comprises the following steps: a first node device receives data sent to a target virtual machine from a source virtual machine, and detects whether the source virtual machine has virtual domain identification, wherein the target virtual machine locates in the first node device which comprises a virtual domain, and the target virtual machine locates in the virtual domain; the virtual domain identification is allocated by a management device, and is used for establishing a virtual domain where the source virtual machine locates through a node device where the source virtual machine locates; and if the source virtual machine has the virtual domain identification, the first node device sends the data to the virtual domain where the target virtual machine locates according to the virtual domain identification of the virtual domain where the target virtual machine locates. The information transmission method and device are suitable for communication transmission between the virtual machines.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to an information transmission method and device. Background technique [0002] Virtual machine technology is an essential technology to realize cloud computing application solutions. In the existing cloud computing solutions, it is necessary to realize the dynamic aggregation of cloud network resources and highly autonomous coordination between each node device in the cloud network, so that the boundary between virtual machines changes from traditional, single, explicit to fuzzy and generalized . [0003] The result of the blurring and generalization of the boundary between virtual machines is mainly: due to the requirements of cloud computing application solutions, it is necessary to realize the smooth communication between virtual machines, which leads to the limitation of communication between virtual machines The degree of reduction makes it possible for virtua...

Problems solved by technology

In practical applications, if there are node devices with low security level in the cloud network, and the virtual machines or virtual domains established on these node devices with low security level, due to the difference between the virtual machines in different virtual domains in the cloud network Occasionally or between different virtual machines in the same virtual domain, the restricted degree of communication is reduced, which actually causes the restricted degree of these node devices with low security level and other node devices in the system to be reduced, so that it is very It is easy to cause data leakage in other node devices in the system
