摘要:

随着视频数据的迅速增长,大规模视频处理业务需求急剧增加.如何及时处理视频数据获取有效信息,进而向用户快速提供视频分析业务是亟待解决的重要问题.针对此问题,提出一种面向大规模视频处理的边缘功能模块化及重组部署方法(EFMR).该方法将视频处理业务下沉到网络边缘,利用网络功能虚拟化,将边缘服务器中的视频业务请求根据其内在相关性进行功能细粒度划分,按需匹配并最大化复用资源,实现重组部署,从而以较小代价实现边缘视频业务处理功能的平滑扩展.实验结果表明,EFMR方法不仅降低了边缘服务器的接入与响应时延、业务的推理时间,而且还节省了大量的计算资源,提高了视频处理业务部署速度.

Abstract:

With the rapid growth of video data, the demand for large-scale video processing tasks increases dramatically. How to process video data in time to obtain effective information and provide users with video analysis services quickly is an important issue to be solved. Aiming at this problem, a new deployment method of Edge Functions Modularized and Reorganized (EFMR) for large-scale video processing is proposed. This method sinks video processing services to the edge of the network. Using network function virtualization, video service requests sent to the edge server are divided fine-grainedly based on their inherent process correlation, and resources are matched and redeployed on demand based on the division results. In this way, we can smoothly expand the edge video service processing capabilities at a small cost. Experimental results show that EFMR method not only greatly reduces the edge server’s access and response delay, reduces the inference time, but also saves a lot of computing resources of edge servers and speeds up the deployment of video processing services.

Key words: mobile edge computing, network function virtualization, modular, reorganized, fine-grained
