Abstract

The invention provides a CDN-P2P (Content Distribution Network-Peer-to-Peer) content optimizing selecting system. The system comprises a source server layer, edge CDN server layers distributed on the edge of a network, and a P2P user layer, wherein the P2P user layer comprises a plurality of service nodes which are divided into a plurality of ISP (Internet Service Provider) domains according to connected ISPs; each ISP includes at least one Tracker node and a plurality of service nodes; each Tracker node includes a receiving module for receiving data uploaded by the service nodes, and a generating module for generating a priority level list for each service node according to the data; the data uploaded by the service nodes includes at least one of ISPs connected with the service nodes and position parameters of the service nodes.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a CDN-P2P content optimization selection system. Background technique [0002] CDN-P2P integrates distribution network technology and has gradually become the mainstream technology for Internet content delivery and sharing. With the wide application of CDN-P2P integrated distribution network technology, the content object service capability has been greatly improved. Due to the decentralized nature of P2P, each content request of a P2P node will find and connect to a service node in the form of broadcast, which may lead to the intercommunication between nodes across multi-layer networks and ISP (Internet Service Provider, Internet Service Provider) domain, and the number of links and routing hops between different ISPs will increase, which will lead to network congestion. It can be seen from this that, on the current ISP backbone network, if the service node is selected...
