Abstract

The invention discloses a p2p (peer to peer) cache file management method and device. The method comprises the following steps: when p2p software is started, inquiring whether a cache file exists from all disks of a user, wherein if no cache files exist in all disks, a disk with largest free space is selected, a cache file is created in the disk, the cache file is stored in a cache container, and cache data is stored in the cache file; and containing one cache container in one disk, and containing one or a plurality of cache files in one cache container. On the basis of a disk use situation of a user, the cache file is established in the disk with the largest free space, other operations of the user are affected, the distribution method does not cause a situation that the single area of the user disk is frequently read and written, so that read-write pressure is disperse, and the service life of the user disk is longer.

Description

technical field [0001] The invention belongs to the field of computers, and relates to a p2p cache file storage method and device. Background technique [0002] With the continuous development of modern network technology, p2p technology (Peer to Peer, p2p for short) has been more and more applied in various fields in the modern network. The most fundamental idea of ​​p2p technology, and also the most significant difference between it and C / S, is that a node (Peer) in a p2p network can not only obtain resources and services from other nodes, but also be a provider of resources and services. With the dual identity of Client and Server. The rights and obligations of each node in the p2p network are equal. [0003] Therefore, the storage and reading of cache files in each node is the cornerstone for nodes to obtain and provide resources and services. A good node cache file storage architecture can not only speed up the data exchange speed between nodes, reduce the hardware r...
