Embodiment 1

[0054] like figure 1 and 2 Shown, a kind of log information network structure method based on P2P on-demand system, comprises the following steps:

[0055] Step 1: Collect user log information;

[0056] Step 2: According to the log information of the nodes, construct a community network structure with users as nodes, relationships between users as edges, and weights expressed by node bandwidth;

[0057] The connection relationship between nodes is calculated by the following algorithm flow:

[0058] 1) The user ID is used as an identifier, and the number of Peers playing the same video URL and the ID of the Peer can be counted at a certain moment, so that a network structure relationship without weight can be formed between nodes.

[0059] 2) Set the weight coefficient according to the bandwidth relationship of the user, so as to form a network structure with weight.

[0060] The above is a coarse-grained calculation process. On the basis of the above calculation process, ...

Embodiment 2

[0105] This embodiment provides a system for implementing the log information network structuring method based on the P2P on-demand system described in Embodiment 1, including the following structure:

[0106] Log collection module 1, used to collect log information of users;

[0107] The community network structure construction module 2 is used to construct a community network structure with users as nodes, relationships between users as edges, and weights represented by node bandwidth according to the user's log information;

[0108] The community structure division module 3 is used to divide the community network structure according to the LabelRank algorithm to obtain multiple communities;

[0109] The LabelRank algorithm relies on 4 operators:

[0110] 1. Transfer operation

[0111] The transfer operation is specifically: define a 1×n vector P at each node to store label distribution, n is the number of nodes; define an adjacency matrix A to store the network structure,...

Abstract

The invention discloses a log information network structuring method based on a P2P program requesting system. The method comprises the following steps of a first step, acquiring log information of a user; a second step, according to the log information of a node, constructing a community network structure in which the users are used as nodes, relationships among the users are used as sides and weight is represented through node bandwidth; a third step, performing community structure dividing on the community network structure according to a LabelRank algorithm; and a fourth step, combining community structure dividing results in the third steps; wherein when data transmission is required, data transmission is performed by means of effective nodes in a corresponding community which is obtained after combining. Furthermore the invention discloses a log information network structuring system based on the P2P program requesting system. The log information network structuring method and the log information network structuring system can effectively handle node testing in crossed communities, thereby forming a more reasonable, more effective and more stable P2P network.

Description

technical field [0001] The invention relates to the field of P2P network and community detection algorithm, in particular to a log information network structuring method and system based on P2P on-demand system. Background technique [0002] With the rapid development of the Internet, multimedia has also grown explosively on the Internet. People are gradually switching from traditional media such as TV and radio to watch audio and video on the Internet. This explosive growth not only leads to a sharp increase in bandwidth traffic costs for resource providers, but also requires network equipment providers to continuously upgrade and transform their networks to increase network transmission speeds. As a new network transmission mode, the P2P network caused a huge shock on the Internet shortly after it was proposed. It is not only a form of software architecture, but also a manifestation of a social model. The P2P network breaks the traditional client-server model and forms a ...
