Embodiment Construction

[0025] In the following description, many technical details are proposed in order to enable readers to better understand this application. However, those of ordinary skill in the art can understand that even without these technical details and various changes and modifications based on the following embodiments, the technical solutions required by the claims of this application can be implemented.

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The first embodiment of the present invention relates to a data flow control method in a video storage system. The video storage system includes a management node and a data node. The management node selects and allocates corresponding data nodes to connect to the outside and perform data storage according to external data input and output req...

Abstract

The invention relates to a video storage system, and discloses a data flow control method and a device thereof in the video storage system. The data flow control method comprises the steps that data samples of data nodes which are relevant to data flow control are collected, a SVR conducts training on the data samples to analyze the samples, and a data flow control SVR regression model is established; the SVR regression model forecasts an output linking number upper limit of the data nodes and a prospective output flow according to a preset qualifying parameter; output linking number of the data nodes and output flow of each linking are regulated according to the output linking number upper limit and the prospective output flow. According to the data flow control method and the device thereof in the video storage system, sample data relevant to the flow control are collected, the prediction model is established, and a flow control target value is obtained through the model, so that the data flow is regulated in a self-adaptive mode, data output efficiency of the video storage system is achieved adequately, external requests can be responded to the maximum extent, and the problems that system operation overloads and resources are insufficient are avoided.

Description

Technical field [0001] The invention relates to a video storage system, in particular to a data flow control method and device in the video storage system. Background technique [0002] The video storage system is based on network technology and distributed technology. It is a system that integrates storage devices in the network through software to work together to provide external video data storage and business access functions. In the video storage system, data output is completed through network transmission, the system processing capacity and network bandwidth are always limited, and the external request of the system at a certain moment is uncertain. How to respond to external requests as much as possible, while enabling the system to operate normally, avoiding overload and insufficient resources, is a contradiction. Storage systems usually have some control parameters. The control parameters for each data node generally include: the upper limit of the number of output co...
