Abstract

The embodiment of the invention discloses an information communication method and device and a computer readable storage medium, and the method comprises the steps of determining the state informationof an access control service when a communication instruction is received; when it is detected that the state information is preset state information, intercepting a transfer event that the virtual address of the target processor is written into the source processor; calculating a real address according to a preset relationship and the virtual address; writing the real address into the source processor, and responding to the communication instruction, so that the source processor realizes information communication with the target processor according to the real address. Therefore, during information communication, the virtual address of the target processor is written into a transfer event of the source processor to intercept, the real address is calculated according to the preset relation and the virtual address and written into the source processor, so that on the premise that the time for translating the virtual address through the upstream device is saved, information communication failure caused by the fact that the source processor uses the virtual address for communication is avoided, and the information communication efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of computer communication, in particular to an information communication method, device and computer-readable storage medium. Background technique [0002] With the development of computer and Internet technology, virtualization technology has developed rapidly. A platform using virtualization technology hides the actual physical characteristics of a specific computing platform. Multiple operating systems can run on one platform, and each operating system can access the resources it needs when needed, thus providing users with an abstract and simulated environment. Computing environment (that is, virtual machines), these virtual machines run in independent spaces without affecting each other, which significantly improves the work efficiency of computers or servers. [0003] In the prior art, a specific application of a virtual machine is a cloud computing platform. The cloud computing platform use...
