Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] Such as figure 1 As shown, the centralized P2P system architecture of the present invention is divided into a management layer, a service layer, and a terminal layer according to functions. The management center server of the management layer realizes content management and node management of the entire P2P system through communication with the service layer. The service layer includes an index server and a super node, where the index server is responsible for collecting the basic information of the terminal and content distribution, so as to provide content location services for the termin...

Abstract

The invention discloses a node management method based on a centralized P2P system. In the process that a request node requests the content service from a neighbor node, based on the comprehensive consideration of a P2P network topology structure and other factors that affect the service quality, service nodes are subjected to screening, dividing, dynamic adding, and elimination, so that the problems of unstable node service quality and single node selection and screening standard of a conventional centralized P2P system can be effectively overcome, and the service quality when the node obtains the content service of the neighbor node is improved.

Description

technical field [0001] The invention is a node management method based on a centralized P2P system, which belongs to the field of multimedia technology. Background technique [0002] Peer-to-Peer (P2P) technology is an important way for streaming media system to distribute content. Compared with the content distribution technology under the traditional C / S (client / server) architecture, the P2P system enables the terminal to use its own computing, storage, and transmission capabilities to achieve content sharing and interaction, and has the ability to maintain large-scale users. The advantage of higher transmission performance. The centralized P2P system is a typical structure of the P2P system. The centralized P2P system has a central index server to collect and store the basic information and content distribution of all nodes in the P2P network. When a node requests content, it first sends a request to the index server, and the index server responds and returns a group of...
