Embodiment Construction

[0008] Reference will now be made in detail to the preferred embodiments of the invention.

[0009] The Caching table structure of the nodes in the P2P network dynamic resource exploration method in normal distribution of the present invention is: Caching table validity flag, 1st level target node address group, 2nd level target node address group, 3rd level target node address group.

[0010] The step that the node of the dynamic resource prospecting method of P2P network sends out the search request during normal distribution of the present invention is:

[0011] When a node is searching, it first checks the validity flag of the Caching table in the Caching table of the node. If invalid, search according to the original search technology.

[0012] If it is valid, the node starts a level 1 cache search: the search request is directly sent to the target node according to the level 1 target node address group, and the target node is required to search in the original search sy...

Abstract

This invention discloses a P2P network dynamic resource prospecting method at normal distribution. When a node utilizes the localization theory to buffer store the node where the possible target resource places, a caching list is needed to be maintained, which registers the distribution of the resource in P2P network required by the node, therefore this Caching list is the resource distribution list and the dynamic prospect of P2P network resource is the method of maintaining this Caching list. The normal distribution is the most common resource distribution way for describing large quantity of resources and the P2P network dynamic resource prospect method is used mostly.

Description

technical field [0001] The present invention relates to a P2P network. The present invention relates to a P2P overlay network resource search method utilizing the principle of locality, and in particular to a dynamic resource exploration method of a P2P network under normal distribution. Background technique [0002] In "P2P Overlay Network Resource Search Method Utilizing the Principle of Locality", when a node caches addresses of nodes where possible target resources are located, it needs to maintain a Caching table. This Caching table records the distribution of resources requested by nodes in the P2P network, so this Caching table is a resource distribution table, and the method of maintaining this Caching table is the dynamic exploration of P2P network resources. Normal distribution is the most commonly used form of resource distribution to describe a large number of resources. At this time, the dynamic resource exploration method of P2P network is the most commonly use...
