Embodiment Construction

[0087] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0088] Such as figure 1 As shown, the method for adjusting the copy file storage capacity of the network node of the present invention mainly includes:

[0089] Determine the network level to which the current network node whose copy file storage capacity is to be adjusted belongs;

[0090] Select other network nodes that are at the same network level as the current network node and belong to the same upper layer network node as the current network node, and form a local network together with the current network node and the selected other network nodes node;

[0091] extracting the link bandwidth and copy file storage capacity of each network node in the local network nodes;

[0092]The copy file storage capacity of the current network node is a...

Abstract

The invention discloses an adjusting method and device of the save file storage capacity of network nodes. The adjusting method comprises the steps that the network layer of a current network node with the save file storage capacity to be adjusted is determined; all network nodes which are located at the same network layer with the current network node and belong to the same upper-layer network node with the current network node are made to form a local network node set; according to the link band width of each network in the local network node set and the save file storage capacity of each network node in the local network node set, the save file storage capacity of the current network node is adjusted. According to the adjusting method and device, the spatial size of the save file storage capacity of the network nodes can be adjusted dynamically according to the changes of network demands, a large storage space can be provided for the network nodes in need of storing more files, the storage space of the network nodes where a few files are stored is reduced, balanced arranging of the storage capacity is realized, the storage utilization rate is increased, services can be pushed to the places nearer to users, the responding time is shortened and the service quality of user experience is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for adjusting storage capacity of duplicate files of network nodes in a service-oriented Internet. Background technique [0002] With the development of technology and the continuous improvement of application requirements, the future Internet will shift from an address-oriented TCP / IP (Transmission Control Protocol / Internet Protocol) architecture to a service-oriented network architecture. In the future Internet, the service requester no longer cares about the location information of the service provider, but the content of the service. The service-oriented Internet architecture fundamentally solves the problems that the existing Internet centered on TCP / IP cannot solve, such as the shortage of IP (Internet Protocol, Internet Interconnection Protocol) addresses and the lack of service quality assurance. [0003] In the service-oriented Internet archit...
