Embodiment Construction

[0027] The present invention will be further described below in conjunction with the 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 ordinary nodes in the network 、 And the resource network composed of all resource nodes in the network. The regional network is divided according to the geographical locations of resource nodes and ordinary nodes. The network can help nodes in the peer-to-peer network to determine 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 aggregates the resources of all resource nodes in the peer-to-peer network, figure 1 The dotted ellipse indicates the resource network.

[0029] Among them, resource nodes refer to no...

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 present 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 method for locating network resources thereof. Background technique [0002] Because the traditional "client / server" computing model exposes problems such as overburdening of servers and difficulty in expanding the application system in applications, this computing model can no longer adapt to the needs of modern Internet development, so P2P network technology emerges at the right time. A P2P network can be simply defined as sharing computer resources or services through direct exchange. The nodes in the P2P network have the dual functions of a client and a server. In this kind of network, all nodes are equal, and each node has the same responsibilities and capabilities and cooperates to complete tasks. Each node realizes resource sharing through direct interconnection, without relying on cen...
