Problems solved by technology

Since the read and write bandwidth of a single storage disk is limited, in the case of large concurrent streaming services, if all streaming services access the same disk, read and write delays or failures will occur, affecting the quality of some streaming services

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 Shown, the present invention is applicable to the data storage method of streaming media service, comprises steps:

[0030] S1. Number all the storage disks sequentially, and record the disk information of each storage disk into the same disk information file in the system disk. The serial number of the storage disk starts from 0, and the storage disk information includes a disk number, a disk letter, a disk serial number, a total disk capacity, a remaining disk capacity and a disk status.

[0031] S2. Each storage disk is divided into multiple disk blocks with the same capacity and size, which are numbered in ascending order according to the starting offset position of the disk blocks; the size of the disk blocks can be specified arbitrarily, but it is required that the size of the disk blocks can be exactly The total capacity of ea...

Abstract

The invention provides a data storage method applicable for media streaming service, and relates to the field of a file system. The data storage method comprises the following steps of numbering all storage disks in sequence, and recording the disk information of each storage disk into the same disk information file; dividing each storage disk into multiple equal-sized disk blocks, and numbering the disk blocks in sequence according to the starting offset positions of the disk blocks from small to large; selecting the storage disks by media files based on an algorithm M=(N-1)%C, in which N represents the number of the media file, M represents the number of the disk storing the media file, and C represents the total number of the storage disks; not only working out the quantity of the required disk blocks, but also selecting a required quantity of disk blocks by the media files; storing the media files into the selected disk blocks, and recording the media file information into content information files. According to the data storage method, the large-concurrency stream service of a stream service node is supported, the storage cost is reduced, and the dynamic update of hot contents and the available normal stream service of the stream service node under the abnormal conditions of the disks are supported.

Description

technical field [0001] The invention relates to the field of file systems, in particular to a data storage method suitable for streaming media services. Background technique [0002] At present, most of the Internet adopts the deployment method of CDN (Content Delivery Network, content distribution network). The media content in the Internet is stored and maintained by the central content library, and provides large concurrent streaming services through the streaming service nodes set up throughout the network. Therefore, the streaming service node only needs to store some hot media content, and the non-existent media content can be obtained from the central content library. [0003] Due to the large amount of media file data and the limited storage capacity of streaming service nodes, it is necessary for streaming service nodes to support not only dynamic updates of hot content, but also large concurrent streaming services; and the current standard file system does not sup...
