Title:
METHOD AND APPARATUS FOR PERFORMING ABSTRACTION FOR LOGIC TOPOLOGY INFORMATION OF PEER TO PEER TECHNOLOGY NETWORK
Document Type and Number:
WIPO Patent Application WO/2010/133114
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a method and apparatus for performing abstraction for logic topology information of peer to peer (P2P) network. The method mainly includes: acquiring the set of points of presence (POP) of peer clients in P2P network, calculating the optimum paths between arbitrary two POPs in the set of POPs and the weights of the optimum paths by using relevant algorithms of routing protocol in P2P network, synthesizing the calculated results of the optimum paths and the weights acquired from each POP, and obtaining the set of the abstracted logic topology records of the P2P network. The embodiments of the present invention provide a universal and effective abstraction method for logic topology information, which decreases the network topology information needing to be transmitted greatly, reduces the risk of the underlying network topology information exposure, and enables the network topology information to be transmitted to P2P application servers safely and refinedly.
