The Cloud Streaming Service Migration in Cloud Video Storage System

Abstract

Video surveillance is used to solve the problems of public security and preservation of evidence. So far, many researchers have offered their secure systems. However, storage and streaming migration issues must be discussed in more detail. In the paper, a method for streaming service migration in a cloud video storage system and the system using the same are provided, and the cloud storage video system includes a directory host, stream processing apparatuses and detection apparatuses. The method includes: assigning a first stream processing apparatus to establish a first stream connection with a first detection apparatus among the detection apparatuses, and assigning at least a second stream processing apparatus to establish a second stream connection with the first detection apparatus but not to receive the video stream data from the first detection apparatus, and assigning the first processing apparatus to receive and store the video stream data from the first detection apparatus, and the second stream processing apparatus receives and stores the video stream data from the first detection apparatus when the directory host determines that the first stream connection is abnormal, and disconnects the first stream connection.
