METHOD AND APPARATUS FOR PERFORMING ABSTRACTION FOR LOGIC TOPOLOGY INFORMATION OF PEER TO PEER TECHNOLOGY NETWORK |
摘要 |
<p>The present invention provides a method and an apparatus for abstracting logical topology information of a Peer-to-Peer (P2P) network. The method includes: obtaining a set of Points of Presence (POPs) of peer clients in the P2P network; using a relevant algorithm of a routing protocol in the P2P network to calculate a best path between any two POPs in the set of POPs and a weight value of the best path; and collecting calculation results of the best path and the weight value that are obtained on each POP to obtain a set of abstract logical topology records of the P2P network. The embodiments of the present invention provide a universal and efficient method for abstracting logical topology information, which greatly reduces network topology information that needs to be transmitted, mitigates a risk of exposing lower-layer network topology information, and transmits the network topology information to a P2P application server securely and concisely.</p> |
