Embodiment Construction

[0026] Due to the diffusion and migration of file copies, the file copy needs to be copied from the source node to the destination node, and the copy operation consumes the resources of both the source node and the destination node. Therefore, from the perspective of resource consumption of the copy operation, it is necessary It is more reasonable to consider how to select source and destination nodes.

[0027] In the embodiment of the present invention, in order to make the selection of network nodes involved in the process of file copy diffusion, migration and deletion more reasonable, a file copy management method is provided, which may specifically include: in a distributed storage network, according to the node Select a source node for flooding or migrating the file copy according to the idle resources of the relevant nodes; the source node selects a destination node for receiving the file copy according to the idle resources of the relevant nodes.

[0028] In order to fa...

Abstract

The invention relates to a method, a device and a system for managing file copies. The method comprises the following specific steps of: in a distributed storage network, selecting a source node for diffusing or transferring the file copies according to idle resources of nodes; and selecting a target node for receiving the file copies by the source node according to the idle resources of relevant nodes. Therefore, in the embodiment of the invention, the nodes with higher resource idle rate can be selected according the current service condition of the resources in a network to transfer and diffuse the copies, so the cost of transferring and diffusing the copies is reduced greatly; and the load pressure of the network is dispersed to save the expenditure of managing the copies, equalize network loads and greatly improve the service performance of the network.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a file copy management method, device and system in a computer network. Background technique [0002] In a distributed storage system, storage servers are used to provide services for files. Based on the requirements of reliability and convenient user access, files stored in the system usually have more than one copy, and the number of these copies is not static during the entire cycle from upload to deletion. As the popularity of files being accessed changes, file copies may need to be diffused, migrated, or deleted. [0003] Since the number of accesses by users to each file in the distributed storage system is uneven, there are relatively hot (highly accessed) files and relatively cold (lowly accessed) files. If a storage server stores a large number of hot files, it will inevitably cause excessive pressure on the storage server; while other storage servers store f...
