A virtual machine-based image processing method for many-to-one access

Abstract

The present invention provides an image processing method based on virtual machine-based many-to-one access, including: creating a simulator and a virtual machine unified service distributor on a server, and several clients access the virtual machine unified service distributor; The machine unified service distributor establishes a buffer I for each connected client to store the ID number of the submap sent to the corresponding client; at the same time, each client locally establishes a buffer h to store the received The submap of the submap, through the cache maintenance mechanism, ensures that the ID number stored in buffer I is completely corresponding to the submap stored in buffer h; when it is necessary to send submap C to the client, it is judged whether it exists in buffer I If the image ID number exists, it only needs to issue the image ID number instead of the sub-image C; the client can obtain the sub-image corresponding to the image ID number by searching the buffer h, and display it on the corresponding screen. location, thereby saving network transmission traffic and improving the speed of submap delivery.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to an image processing method based on virtual machine-based many-to-one access. Background technique [0002] With the promotion of virtual machine applications, the demand for multiple clients to connect to the same virtual machine also arises, for example: monitoring, playing slideshows, playing movies, and so on. [0003] Take playing slideshow as an example. For example, if 5 clients are connected to the same virtual machine, if 100 slideshows need to be played sequentially, the processing method is: while the virtual machine is playing the first slideshow, set the The first slide is sent to 5 clients respectively through the network, and the 5 clients display the image of the first slide respectively; then, while the virtual machine plays the second slide, the second slide slides are sent to 5 clients through the network respectively, then the 5 clients ...

AI Technical Summary

Problems solved by technology

It can be seen that the virtual machine needs to deliver 100 slides to 5 clients through the network, so that 5 clients can watch the virtual machine played by the virtual machine, which has the problems of large data transmission volume and serious network bandwidth occupation. ; Moreover, because the screen image usually occupies a large bandwidth, there is also the problem that the transmission speed of the screen image in the network is slow, which affects the viewing experience of the client
