Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] see figure 1 , figure 1 It is a schematic diagram of the peer-to-peer network structure of the present invention. The entire peer-to-peer network includes a regional network composed of resource nodes and common nodes in the network 、 And a resource network composed of all resource nodes in the network. The regional network is divided according to the geographic location of resource nodes and ordinary nodes, and the network can help nodes in the peer-to-peer network to judge the distance between other nodes and the node, figure 1 Each solid ellipse in represents a regional network. The resource network is composed of all resource nodes in the network, and the network gathers the resources of all resource nodes in the peer-to-peer network, figure 1 The middle dotted ellipse represents the resource network.

[0029] Among them, a res...

Abstract

The invention discloses a peer-to-peer network. The peer-to-peer network comprises local area networks and resource networks, wherein the local area networks are composed of resource nodes and common nodes and are partitioned according to locations of the resource nodes and the common nodes, and the resource networks are composed of all resource nodes in the network and can assist the nodes of the peer-to-peer network in evaluating relative distance with other nodes. The resource networks are composed of all resource nodes in the peer-to-peer network and integrate resources of the resource nodes in the peer-to-peer network. The invention further discloses a network resource location method based on node heterogeneity in the peer-to-peer network. By the peer-to-peer network and the network resource location method thereof, quick location can be realized, target resources can be acquired nearby, and higher network transmission performance can be realized.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a peer-to-peer network (Peer-to-Peer Network, P2P network for short) and a network resource positioning method thereof. Background technique [0002] Because the traditional "client / server" computing model exposes such problems as the server's overload and the application system is difficult to expand, the computing model can no longer meet the needs of the development of the modern Internet, so P2P network technology emerges in due course. A P2P network can be simply defined as sharing computer resources or services through direct exchange, and nodes in a P2P network have dual functions of both client and server. All nodes in this network are equal, and each node has the same responsibility and ability and cooperates to complete the task. The sharing of resources is realized through direct interconnection between nodes without relying on centralized server support. T...
