Embodiment Construction

[0025] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail 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 with the outside according to external data input and output requests, and performs d...

Abstract

The invention relates to a video storage system, and discloses a data flow control method and device in the video storage system. The data flow control method of the present invention includes the following steps: collecting data samples related to data flow control of data nodes; SVR support vector regression machine trains the data samples to analyze the samples, and establishes a data flow control SVR regression model; the SVR regression model is based on the preset Set the limited parameters to predict the upper limit of the output connection number and the expected output flow of the data node; adjust the output connection number of the data node and the output flow of each connection according to the upper limit of the output connection number and the expected output flow. In the present invention, the sample data related to flow control is collected and a prediction model is established, and the target value of flow control is obtained through the model, and the data flow is adaptively adjusted accordingly, so as to give full play to the data output efficiency of the video storage system, which can maximize Respond to external requests to the maximum extent, and avoid the problems of system overload and resource shortage.

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, etc., and integrates storage devices in the network to work together through software to provide video data storage and business access functions to the outside world. 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 is uncertain at a certain moment. How to respond to external requests to the maximum extent and make the system run normally, avoiding overload and resource shortage is a contradiction. The storage system usually has some control parameters. The control parameters for each data node generally include: the upper limit of the output connection number, th...
