Storage adjustment method, device and system for contents in streaming media system

Abstract

The invention discloses a storage adjustment method, a storage adjustment device and a storage adjustment system for contents in a streaming media system. The method comprises the following steps that: a resource directory index server periodically acquires a load of each content server (CS) in the whole network and a resource identifier which is stored in the CS; the resource directory index server periodically counts access frequency values of all resources in the whole network; when the access frequency value of one resource decreases to a preset frequency lower limit value, the resource directory index server selects the CS with a large load from the CSs in which the resource is stored, and sends a deletion instruction which carries the resource identifier to the selected CS; and when the access frequency value of one resource increases to a preset frequency upper limit value, the resource directory index server selects the CS with a small load from the CSs in which the resource is not stored, and sends the contents of the resource to the selected CS. By the invention, the contents of the resource can be optimally stored in the whole network.

Description

technical field [0001] The invention relates to the technical field of content storage, in particular to a content storage adjustment method, device and system in a streaming media system. Background technique [0002] Point-to-point (P2P, Peer to Peer) technology is a distributed technology, which belongs to the category of Overlay Network, and is another way of network information exchange relative to the client / server (C / S) mode. The P2P network is a peer-to-peer network structure. In the P2P network, each node can obtain services from other nodes and provide services to other nodes. In this way, huge terminal resources are utilized. [0003] Streaming media refers to continuous real-time media using streaming technology in the Internet / Intranet, such as audio, video or multimedia files. During streaming, real-time media such as sound, video or animation are transmitted continuously and in real time from the audio and video server to the user's computer. The user does n...

Problems solved by technology

[0018] CS storage adjustment logic does not have a network-wide perspective, that is, when CS performs storage logic, it only pays attention to what content needs to be deleted locally, but cannot pay attention to what content needs to be deleted on the entire network

In addition, according to the instructions of Tracker, when CS distributes "hot" content, if it needs to perform cache replacement operation, it needs to ensure the integrity of the content, which cannot be achieved by existing methods
