Embodiment Construction

[0039] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Contrast attached figure 1 And attached image 3 , it can be seen that before the network video enters the system for storage, the default storage method is to store the video data into small files one by one through the virtual file system, and then write the video data into the disk cache through the file method. Finally, the data is written to the hard disk from time to time. The invention improves the whole data storage process aiming at the particularity of streaming media data.

[0041] See attached figure 1 , the front-end network video data enters the system for storage. At this time, it directly enters the virtual file system, and abandons the practice of storing data through files first, and then the data enters the custom cache system (this cache is allocated by the system memory), instead of Enter the default disk cache ...

Abstract

The invention relates to a block storage algorithm applicable to multiple paths of concurrent-written stream media data. In the security and protection monitoring industry, requirements on the storage property of a video server are higher and higher as the project scale is continuously expanded and a high-definition front-end camera is used. A bottleneck formed by concurrent writing of hundreds of external video data of the camera into a single storage server is analyzed. A file system breaks down easily and the data is seriously lost under the abnormal condition of the server. After a disk is repeatedly covered and written, a large number of disk fragmentations are generated and the storage property is also reduced. According to the invention, the problems are analyzed, and a strategy for establishing a self-cache system through bypassing a file system layer, as well as a block storage idea and an available block searching algorithm on the basis of the block storage idea are provided. Through the online use of a practical product, the feasibility and the reliability of the block storage algorithm are verified.

Description

technical field [0001] The invention is mainly used in the field of security network video monitoring, and provides an optimized storage algorithm for streaming media data generated in network video monitoring, which can be applied to all storage devices in network video monitoring to ensure data Efficient, optimized storage. Background technique [0002] In recent years, with the construction of building security, park security and safe cities, networked video surveillance has shown a rapid growth trend. Video data has changed from standard definition to high definition, and streaming media data generated by network cameras is transmitted to video servers through the network. , need to be stored and saved for a certain number of days, so that the user can play back the video when certain events occur. Therefore, the proportion of storage in network monitoring is also increasing, and its data security and stability are particularly important. Therefore, the storage requirem...
