Embodiment Construction

[0031] The method for realizing P2P file sharing proposed by the present invention is mainly applied in a P2P file sharing system. As shown in FIG. 1 , in the P2P file sharing system, the personal computer owned by each user is a node (Peer) in the P2P system, and multiple files are stored on each node. There are relations of competition, cooperation, constraints and restrictions among different files on different nodes. Wi, Wj, Wk, and Wl in the figure indicate that there is a collaborative relationship between the files on the connected nodes, that is, there are such files on these nodes, and the relationship between them is copying and being copied, in other words, they have the same files, these files can cooperate with each other, and the present invention assigns the relationship between such files to be managed by nodes.

[0032] Figure 2 is a schematic diagram of the file collaboration network in the P2P system of the present invention, mainly illustrating the collabo...

Abstract

The disclosed active P2P file share method adds series active features to the passive file to make the file into active one with life feature and overcome defects in traditional system, describes user PC as the resource for file consumption and competition to provide basis and necessary for file active propagation, and prepares a set of competition and cooperation rules according with natural evolution principle to define action regulation for guiding and constraining active file. This invention improves description and construction on life cycle and action model for active file.

Description

technical field [0001] The present invention relates to a method for realizing resource sharing in a network environment. Specifically, the present invention relates to a method for realizing file (resource) sharing in a P2P network environment based on ideas such as collaboration and competition. Background technique [0002] With the development of computer and network technology, the storage, computing power and access bandwidth capabilities of personal computers have been greatly improved, and more information resources are available on personal computers. How to link these personal computers together and share resources on each computer more conveniently and effectively has become a very challenging problem. At the end of 1998, after Napster, the first real P2P file sharing system, appeared, P2P technology became a much-concerned method to solve this problem. Prior to this, the mainstream resource sharing mode was the client / server mode. The resources were mainly store...
