Problems solved by technology

However, h264 encoding requires additional time overhead, and the entire process of compression and decompression will cause a certain time delay. From the user's point of view, it means that the operation response lags: the user will only see the operation after a delay of a few tenths of a second. The final effect affects the user's experience of the cloud desktop

Abstract

The invention discloses an optimization method for image processing in an SPICE cloud desktop. The optimization method comprises the following steps: installing a libjpeg-turbo library on an SPICE server; when a connection is established between the SPICE client and the SPICE server, enabling the SPICE server to perform automatic testing and record the currently connected network bandwidth, maintaining the data traffic per second from the SPICE server to the SPICE client, and recording the updated data traffic per second at this time and the updated data traffic per second at the last time, so the speed and the compression rate of image compression of the SPICE cloud desktop, especially JPEG lossy image compression, are improved, the data transmission quantity of the SPICE cloud desktop under high resolution is controlled within 10M / s, and smooth experience of the SPICE cloud desktop in a low-bandwidth environment is ensured. Meanwhile, the universality and compatibility of the optimized SPICE cloud desktop are ensured, and the client can be ensured to normally interact with the cloud desktop on the premise of not changing.

Description

technical field [0001] The present application relates to the technical field of cloud desktop image transmission, in particular to an optimization method for image processing in SPICE cloud desktop. Background technique [0002] Cloud desktop is a typical application in the era of virtualization and cloud computing. By building a server cluster in the cloud data center, creating multiple virtual machines, and users remotely connecting to the virtual machines through cloud terminal devices, the cloud desktop can provide users with the same experience as the local PC. This technology allows administrators to only need the cloud data center for centralized system maintenance, which greatly reduces the workload of administrators, and also makes users no longer need to worry about data loss caused by local PC failures. It is increasingly favored by enterprises and individuals. favor. [0003] SPICE cloud desktop is mainly composed of three parts: SPICE protocol, SPICE server a...
