Abstract

Disclosed is a P2P (peer-to-peer) network node selecting method. The method includes: through an IP (internet protocol) address mapping library of a Tracker server, performing fast coarse granularity division on existing nodes to enable the divided nodes to have same location information, and selecting a final node list possessing requested media resources according to the location information of a request node; performing improved node selecting for delay measurement on the nodes returned by the final node list, performing electric strength test on the nodes in the node list by the request node, increasing the number of download data blocks so as to fast acquire the nodes preliminarily meeting the requirements, and selecting most suitable nodes as neighbor nodes. The method has the advantages that networking is simplified without participation of operators, establishment and maintenance cost is low, network-to-network flow is reduced, flow among operator interfaces is reduced, data congestion of a backbone network is avoided, the needed neighbor nodes can be selected fast, the selected nodes are fast in response and high in bandwidth.

Description

technical field

[0001] The present application relates to a method for connecting Internet nodes, in particular, relates to a method for screening P2P2 network nodes. Background technique

[0002] At present, with the development and popularization of the Internet, the P2P technology has become a widely concerned technology. P2P network is a kind of overlay network. Overlay network refers to a network built on another network. Simply put, it is to build a network system completely located at the application layer on the existing Internet. It is oriented to the application layer and does not consider Or seldom consider the information of network layer and physical layer.

[0003] An important concept in the P2P network is that neighbor nodes, that is, nodes that have an application layer connection with the current node, are connected to each other topologically. If the current node has data exchange with a neighbor node, the quality of the connection between the two becom...
