Embodiment

[0037] As shown in FIG. 2 , it is a schematic diagram of a method for sharing resources in a distributed index in a P2P network in an embodiment. Among them, devices 1 to 8 are 8 devices distributed in various places in the P2P network, and their status is equal in the P2P network. However, in this embodiment, device 1 is the initiator node of the resource distributed index, device 2, 3. Device 5 and Device 6 serve as relay nodes for message forwarding, while Device 4, Device 7 and Device 8 serve as terminal nodes for publishing resource distributed indexes.

[0038] The method of publishing the shared resources in this example on the distributed index in the P2P network is as follows:

[0039] As shown in Figure 2, the user of device 1 wants to share some of his own resources, such as a TV series named "Happiness is Like a Flower". According to the preset setting, the system extracts the name "happiness is like a flower" representing the resource as the keyword of the shared...

Abstract

The invention relates to a P2P network technology, in particular to the resource index and discovery method based on distributed hashtable (DHT) in P2P network. Aiming at the defects of incapability of making fuzzy search, low inquiry efficiency and instability of hit ratio for shared resources in P2P network, the invention discloses a P2P network resource-sharing method by multi-keyword technology. The invention utilizes multi-keyword technology to conduct distributed index and discovery of resource so as to release and discover one shared resource via different paths, thus realizing 'fuzzy' search for resources. The invention has the advantage of that fuzzy search can be conducted by multi-keyword so that the resource inquiry efficiency is enhanced greatly. Additionally, with the advantage of the DHT technology, the invention can well conduct distributed storage of resources and can maintain good scalability, reliability and load balance among network nodes.

Description

technical field [0001] The present invention relates to P2P network technology, in particular to resource index and discovery method based on distributed hash table in P2P network Background technique [0002] In recent years, with the rapid development of computer technology and network technology, home networks have become increasingly popular, and resource sharing through the network has also become very popular. Peer to Peer (P2P) technology is a new network resource sharing technology developed in recent years, which is completely different from the traditional C / S (client / server) structure of network resource sharing. Technology. P2P technology is completely separated from the central server, and each node in the network is both a server and a client, making each node completely equal in the network. In a P2P network, each node has a unique identifier (ID). [0003] P2P technology can be divided into structured P2P network sharing mode and unstructured P2P network s...
