Embodiment Construction

[0042] The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

[0043] In order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0044] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

[0045] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] In this embodiment, the user end records video through the camera to generate video data, and the user end compresses the video data before uploading it to the edge server for buffering, so as to reduce the amount of uploaded data. The edge server is deployed close to the edge of the network where the video data is generated, and has stronger data computing capabilities than the client,...

Abstract

The present invention relates to the field of cloud computing, and provides a video frame dispatching method based on edge computing. The method comprises the following steps of: generating a video task by a user terminal, performing compression of the video frame number, and sending a resource condition consulting request to a controller; receiving the request of the user terminal by the controller, and obtaining edge server resource information to each edge servers capable of being connected; updating an edge server list by the control terminal; calculating resource values c* and m* of the video task when the load is lowest in the range of the remaining resource of the edge servers by the controller; confirming a serial number e* of the edge server with the shortest total delay of the current task processing by the controller, and sending the edge server information to the user terminal; and sending the video task to the edge server with the serial number of e* for processing by theuser terminal, and uploading the processing data to a cloud server for storage, statistics and analysis after the edge server completes processing. The video frame dispatching method based on edge computing can effectively reduce the transmission and processing delay of the video task and can improve the resource utilization rate of the edge servers.

Description

technical field [0001] The present invention relates to the field of cloud computing, and more specifically, to a video frame scheduling method based on edge computing. Background technique [0002] The popularity of smart devices and the improvement of public monitoring systems have produced a large amount of video information, and more and more users are not only receivers of video information, but also producers of video information. The upgrade of the camera equipment has greatly improved the resolution of the video stream, and at the same time made the capacity of the video file larger, and the large-capacity video file is a great challenge to the bandwidth of the network and the processing capacity of the server. . Under the constraints of network bandwidth and server computing power, the transmission and processing of massive video files will generate a large delay, seriously affecting user experience and monitoring effects. [0003] In the field of video processing...
