Problems solved by technology

[0003] Although the desktop cloud has many advantages compared with the traditional PC, it has the problem that it cannot support the smooth playback of ultra-high-definition resolution videos. If resource consumption is too large, user experience will be very poor, which significantly restricts the rapid development of desktop cloud

Embodiment

[0026] Such as figure 1 As shown, in the desktop cloud scenario, one server can connect to multiple clients, and each terminal device has a virtual desktop. The virtual desktop is transmitted between the client and the server through the SPICE protocol, and the SPICE Server is run on the server. Run the SPICE Client in the client, and the two cooperate with each other to complete the transmission of the virtual desktop according to the SPICE protocol.

[0027] Such as figure 2 As shown, the SPICE protocol is divided into multiple communication channels such as video, image, audio, keyboard and mouse, USB, and others. Each communication channel is implemented for a different function, and each channel is a socket. In order to improve the user experience, it is mainly optimized for the two channels with the largest transmission volume of video and images.

[0028] Such as image 3 As shown, the physical hardware customizes a dedicated FPGA accelerator card, which encapsulate...

Abstract

The iinvention method for optimizing the virtual desktop transmission based on the FPGA. A server side, a client side and an SPICE Server side are included; the server side is additionally provided with an FPGA card with a 10-gigabit network port. The method includes: transforming the SPICE Server end: enabling the SPICE Server end to directly call the FPGA to carry out video image compression ofthe desktop and a video, and directly sending the compressed desktop and video to the client through the network port; carrying out decompressing and displaying in the client by utilizing hardware characteristics; for information of other channels such as a keyboard and a mouse, a USB and the like, directly sending the information through the FPGA. The method provided by the invention not only can ensure ultrahigh video playing, but also can reduce consumption of physical resources at the same time. The invention mainly aims to solve the problem of poor user desktop experience in a virtualization environment, and provides a method for optimizing virtual desktop transmission based on an FPGA based on an SPICE virtual desktop transmission protocol.

Description

technical field [0001] The invention belongs to the technical field of virtual desktops, in particular to a method for optimizing virtual desktop transmission based on FPGA. Background technique [0002] With the development of cloud computing technology, desktop cloud technology is also developing rapidly. The desktop cloud adopts the operation mode of cloud terminal plus server, and the storage and operation of data are concentrated on the server. Smart distribution. It ensures the effective use of performance and reduces the investment in PC purchase. When the server does not reach the upper limit, it is only necessary to add terminals. Moreover, the data is stored on the server. Whether it is an unexpected power failure or an operation error that makes the terminal suddenly unusable, it can effectively ensure that the data will not be lost and reduce unnecessary losses caused by emergencies. Another benefit brought by centralization is the convenience of later maintena...
