A CONTENT BUFFERING, QUERYING METHOD AND POINT-TO-POINT MEDIA TRANSMITTING SYSTEM

摘要

A method for caching content is provided, which includes caching obtained media data content in a form of content blocks; clustering ordinary nodes according to the content; and selecting one or more management nodes to manage the cluster of the ordinary nodes caching the same content, and recording address information of all nodes in the cluster and information of the blocks containing the content. A method for querying content, a point-to-point (PTP) media transport system, and a management node are further provided. Thus, ordinary nodes are able to utilize contents stored by other users conveniently and effectively, thus enhancing the searching accuracy and efficiency of the user, overcoming the defect of low searching efficiency in the conventional art, and reducing the load of the server.
