Time correlative peer-to-peer network organizing method in demand stream media system

Abstract

The invention discloses a time-related peer-to-peer network organization method in a streaming media on-demand system. Each node performs the following steps: ① creating a node list; ② recording the node information of all nodes in the same channel; Whether the current playing time of each node is adjacent to it; ④ establish a "neighbor" relationship with each node adjacent to the current playing time; Exchange information; ⑦judging whether its "neighbor" node caches the required data; ⑧establishing a "partner" relationship with the node that caches the data it needs; ⑨judging whether the playback is over. The invention selects the nodes with adjacent playing time by the nodes, and then selects the nodes with the required data cached, and establishes the connection. The invention ensures the stability and dynamics of the system, eliminates "single point of failure", and improves the accuracy of information acquired by nodes.

Description

technical field [0001] The invention belongs to the field of computer applications and relates to a time-related peer-to-peer network organization method in a streaming media on-demand system. Background technique [0002] The application of streaming media technology has always been the main way to disseminate multimedia information on the Internet. With the increasing popularity of broadband networks, streaming media on-demand services have attracted increasing attention. [0003] The traditional streaming media on-demand system stores a large amount of streaming media data to be on-demand on a group of centrally managed video servers, and the video server is responsible for responding to each client's on-demand request. In this client / server system model, the video server does all the work. When the number of on-demand users continues to increase, the video server will eventually reach its capacity limit. In order to enhance the service capability of the system, the com...

Problems solved by technology

However, when the nodes in the system frequently join or exit, the system needs to spend a considerable price in order to maintain this "tree" logical network organization structure, especially when some key nodes fail, the "tree" "The logical network organization structure almost needs to be refactored, which will have a subversive impact on the system

Therefore, the network organization method of "tree" structure cannot be well adapted to the peer-to-peer network on-demand system
