Resource node selection method supportive of P2P (peer to peer) traffic optimization

Abstract

The invention provides a resource node selection method supportive of P2P (peer to peer) traffic optimization. The method includes: receiving resource node information sent by a resource information storage entity in a P2P overlay network, wherein the resource node information includes IP (internet protocol) addresses of user nodes and a resource node list of IP addresses of each resource node corresponding to resources requested by the user nodes; calculating a link cost table and a network arear division table according to dynamic network information; and respectively determining resource priority value of each resource node relative to the user nodes according to the link cost table, the network area division table, the IP addresses of the user nodes and the IP addresses of each resource node in the resource node list, and combining a node available connection number to return an optimized resource node list to the user nodes to dynamically adjust the resource priority values. By the resource node selection method supportive of P2P traffic optimization, P2P traffic passing through a backbone network can be lowered, traffic localization can be realized, and influences on other services can be reduced.

Description

Technical field [0001] The invention relates to computer network technology, in particular to a method for selecting resource nodes supporting P2P traffic optimization. Background technique [0002] A peer-to-peer (P2P) network is a technology used to directly exchange data or services between different user nodes, that is, personal computers (PC) without relay equipment. In a P2P network , All user nodes are in a peer-to-peer position. Each user node in the network can not only act as a client, but also as a server to provide resources and services to other user nodes. Due to the advantages of P2P network architecture, P2P services have appeared in large numbers in recent years. Most content providers use P2P technology to provide users with related services. However, while a large number of P2P technology-based services are launched, a large amount of bandwidth in the network has been used by P2P. Traffic is swallowed. Data shows that more than 70% of the network bandwidth is ...
