Embodiment Construction

[0067] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0068] Some solutions are proposed in the related art to reduce the frequency of interaction between the virtual sending end and the virtual receiving end running in the host during a data transmission. For example, allocate a large shared memory area within the host. The disadvantage of this is that when there are many VM-VM pairs or VM-Host pairs that need to communicate through shared memory on the host, a large memory is allocated for each VM-VM pair or VM-Host pair It will cause insufficient host memory, which will seriously affect the performance of the host. Moreover, when the length of data transmitted by a VM-VM pair or a VM-Host pair is less than ...

Abstract

The invention aims to provide a method and device for switching a shared memory area, a storage medium and electronic equipment so as to solve the problem of low performance of communication between avirtual sending end and a virtual receiving end based on a host shared memory area in the prior art. In order to achieve the purpose, the invention provides a method for switching a shared memory area, the shared memory area is located in a host, and a virtual sending end and a virtual receiving end run on the host. The method comprises: acquiring data parameter information of communication datasent by the sending end in history, judging whether the data parameter information meets a preset parameter condition or not, and if the preset parameter condition is met, generating an instruction for instructing to switch the shared memory area used by the sending end and the receiving end.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method and device for switching a shared memory area, a storage medium, and an electronic device. Background technique [0002] With the development of computer technology, communication scenarios between virtual machines to virtual machines (VM-VM) and virtual machines to hosts (VM-Host) are increasing day by day. A common method is to perform VM-VM communication or VM-Host communication through a TCP / IP network. However, this method has disadvantages such as high communication delay and low bandwidth. In related technologies, in order to reduce the communication delay and increase the communication bandwidth, a scheme of performing communication from a virtual machine to a virtual machine and from a virtual machine to a host by reading and writing a shared memory is proposed. [0003] Specifically, process a in virtual machine 1 and process b in virtual machine ...
