Problems solved by technology

If too many requesters send search messages at the same time, a large number of query messages will flood the network, which will inevitably lead to information explosion; at the same time, the search efficiency is low and the amount of calculation is large

Embodiment Construction

[0021] The working mode of the present invention will be described below with reference to the accompanying drawings.

[0022] figure 2 is a schematic diagram illustrating the principle of generating and transmitting metadata according to a preferred embodiment of the present invention. figure 2 The P2P network 200 includes several peer nodes (denoted by 201-206, respectively). It should be understood that figure 2 It is shown that the P2P network includes 6 nodes, but the present invention is not limited thereto, and the actual P2P network may include any number of nodes. Each node in the network 200 can send metadata M to its neighbors in advance (preferably, during network idle time) (for simplicity, only node 201 is shown in the figure to send the metadata to its neighbor nodes 202-206 M, and the situation that other nodes send to neighbor nodes is not shown), to indicate or claim that the node 201 has content that can be shared with neighbors. By maintaining inform...

Abstract

The invention discloses a method for searching resource in P2P network, which comprises the following steps: receiving metadata from other peer-to-peer nodes in advance, wherein the metadata of each node comprises shared file information in the peer-to-peer node; responding to a requirement for requesting specific resource from other peer-to-peer nodes; judging which peer-to-peer node claims to have the specific resource according to the received metadata; and transmitting the request to the peer-to-peer node which claims to have the specific resource. By using the method, the traffic in the P2P network can be remarkably reduced, and the phenomenon of message delay and message explosion in the network traffic peaks can be reduced or avoided.

Description

technical field [0001] The present invention relates to a computer network, and more particularly, the present invention relates to a method and device for fast searching in a computer network. Background technique [0002] With the development of network technology, it is becoming more and more common to search and share resources on the Internet (Internet), especially in peer-to-peer (P2P) networks. Common software for searching and sharing resources in the P2P network includes Thunder, bt, emule, etc. However, at present, the speed of searching in these software is usually not ideal. [0003] figure 1 A P2P network 100 is schematically shown. The P2P network 100 includes multiple nodes, and each node is peer-to-peer. If one of the nodes (for example, node 101) has a request to obtain a specific resource from other nodes, the node 101, as a requester, sends a request to its neighbor nodes (for example, figure 1 Nodes 102-105 in ) multicast the search message. After r...
