Method and device for predicting residual online time of peer in peer-to-peer network
First Claim
1. A method for predicting a residual online time of a peer in a peer-to-peer (P2P) network, the method comprising:
- obtaining, by a peer node in the P2P network, M history life cycle sampling data Si of the peer node, wherein i=1 to M and the history life cycle sampling data comprises a history starting online time point and a history online time of the peer node;
determining, by the peer node in the P2P network, Gaussian components n in a multidimensional Gaussian Mixture Model to be established, wherein n is a positive integer greater than or equal to 2, and the multidimensional Gaussian Mixture Model denotes a probability distribution of the residual online time of the peer node;
utilizing, by the peer node in the P2P network, Si and n to establish a multidimensional Gaussian Mixture Model; and
predicting, by the peer node in the P2P network, the residual online time of the peer node by utilizing the multidimensional Gaussian Mixture Model.

Abstract
A method for predicting a residual online time of a peer in a peer-to-peer (P2P) network is provided. The method includes: obtaining M history life cycle sampling data Si of a peer, i=1, . . . , M; determining the number, n, of Gaussian components in a multidimensional Gaussian Mixture Model to be established, where n≧2, and the multidimensional Gaussian Mixture Model denotes a probability distribution of a residual online time of the peer; using Si and n to establish the multidimensional Gaussian Mixture Model; and using the established multidimensional Gaussian Mixture Model to predict the residual online time of the peer. A device for predicting a residual online time of a peer in a P2P network is also provided.
