Aggregation method and system of nodes mapping and fusing much information

Abstract

The invention relates to an aggregation method and a system of nodes mapping and fusing much information. The method is used for screening out nodes which can be used as node clusters in N adjacent nodes according to network delay characteristic and content characteristic in a distributed type network. The method includes steps of (1) carrying out an analogy on the network delay and content knowledge amount and other parameters between a node and adjacent nodes with spring elasticity and the universal gravitation, (2) respectively mapping the spring elasticity and the universal gravitation of the node into elastic potential energy and gravitational potential energy, and carrying out potential energy analogy, and (3) calculating the sum of the potential energy of the node, and finding out cluster collections which enable the total potential energy between the node and the adjacent nodes to be largest, for all nodes in the N adjacent nodes according to the potential energy sum. According to the aggregation method and the aggregation system, node collections with low delay and similar contents can be found, efficient cooperation of the node collections in the network calculating process is helped, and service quality is guaranteed.

Description

technical field [0001] The invention relates to a service network structure composed of distributed nodes, in particular to a node aggregation processing method and system based on multiple information mapping and fusion. Background technique [0002] At present, the research on service virtualization network oriented to media services is an emerging topic, so some new contradictions have emerged, including: streaming media is a content-related service, which is mostly ignored in traditional network modeling methods, Therefore, how to integrate multiple information sources, aggregate nodes with relatively high performance, and build a network for service nodes in a wide-area environment is a key issue. [0003] In a wide-area environment, no matter in a P2P network or a content distribution network (CDN), it is mostly necessary to establish an overlay network (Overlay) structure between nodes, and use the overlay network structure to complete resource sharing. Traditional o...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the existing node aggregation and grouping algorithm only considers single-dimensional influencing factors, such as geographical location, network distance, etc., resulting in the low network service capability of the nodes selected by these factors, thereby providing a A node aggregation method and system for multi-information mapping and fusion
