Description

[0001] The present invention relates to a graphics processing system capable of improving the rendering performance of a web-based VDI,

The present invention relates to a graphics processing system for improving the rendering performance of a web-based VDI, and more particularly, to a web-based VDI protocol performance improvement function for improving graphics processing performance, And more particularly to a graphics processing system that improves the rendering performance of a web-based VDI that provides seamless web-based VDI services in response to an access environment.

Due to recent advances in hardware fabrication technologies such as CPU and memory, low-cost, high-performance personal computers (hereinafter referred to as PCs) are rapidly spreading, and the computing power of PCs has improved to the level of the initial supercomputer.

As the performance of personal computers is improved, the software used on personal computers is also demanding to accommodate increasingly colorful user interfaces and graphics intensive work.

In addition, graphics hardware technology is applied not only to existing graphics intensive tasks such as 2D / 3D and multimedia, but also to web browser rendering, flash, and Windows operating system.

Server-based software services (ie, server-based computing environments) are being applied to solve problems such as data security and PC management costs that occur in PC-based computing environments.

Technologies that support server-based software services include Citrix's XenDesktop, VMWare's VDI, and Microsoft's Terminal Services based on Remote Desktop Protocol (RDP).

For example, in order to service 3D and virtual reality contents, a 3D scene and related data are transmitted from a server to a client located at a remote place, and a technique of expressing the 3D scene and related data in a client of the user is provided. The 3D scene and related data generated by the vertex shader and the pixel shader, which require 3D acceleration for the server, are transmitted to the client of the user and the 3D streaming is realized through the 2D rasterizer at the user's client.

As described above, in the conventional server-based software service, the software is executed in the server, and the client PC performs only the terminal role. Therefore, the load of the server increases as the number of clients increases.

In addition, the conventional server-based software service has a limitation in processing high-performance graphics tasks such as 3D rendering by using a method of transmitting the result image executed in the server to the client.

Therefore, conventional server-based software services have problems such as resource waste of high-end client PCs, service limit due to server load, enormous server purchase cost, and slow service performance.

In a conventional server-based software service, a session management technology that is dependent on an operating system (OS) or a desktop service supports a plurality of users on a single server through a virtual machine.

This has a problem that OS dependency of a server providing a server-based software service, introduction cost of a server due to load of a virtual machine, and management constraints occur.

In recent years, with the spread of smartphone terminals and the development of wireless networks, VDI users' access environment has expanded from PCs to mobile terminals such as smart phones and tablets, and the need for web-based VDI protocols is increasing.

The existing web-based VDI protocol has a structure that is somewhat inappropriate for the web environment, such as client rendering and the use of the unsupported image format.

Accordingly, there is a need for a web-based concrete technique for improving the graphic processing performance in consideration of the web standard and adapted to various user access environments.

1, a graphics processing system for improving the rendering performance of a Web-based VDI according to an exemplary embodiment of the present invention includes a guest OS 10, a QEMU 30, a VDI service unit 100, , And a client device (200).

In order to provide a service pursued by the present invention, the VDI protocol is divided into three types, namely, host rendering, client rendering, and screen scraping, Loses.

Since the client rendering method performs graphic rendering at the client end, the amount of data to be transmitted from the host to the client is small, but a client with a certain performance or more is required.

The existing web-based VDI protocol mainly uses the client rendering method, but the client rendering method is not suitable because the web lacks the graphic rendering performance compared with the native application due to the multi-layer and hardware access restriction.

Disruption caused by graphic rendering delay degrades the quality of VDI service and user satisfaction.

And while the Web only supports limited image formats such as JPEG, GIF and PNG, the existing Web-based VDI protocol uses a variety of other image formats.

In addition, if a proxy server is used for communication with a web client, only a lot of computing resources are consumed and wasted only in data format conversion.

Accordingly, the present invention provides a Web-based VDI protocol structure for enhancing graphics processing performance that can improve the performance and resource efficiency of the Web-based VDI protocol because it minimizes the traffic according to the client access environment based on the host rendering.
