Abstract

The invention is a service scheduling method for a content distributing network, applied to a content distributing network comprising terminals and service nodes, where the service node comprises guiding unit and media unit; and the method comprises the steps of: A. a terminal initiates a searching request for it address and media content information to a guiding unit in its local area; B. if this local area does not have the media contents, adopting P2P protocol to transmit the searching request above to other service nodes; C. the guiding unit of a service node having the media contents sends searching request response to the terminal; D. the terminal sends service application information to the guiding unit of the service node having the media contents; E. the guiding unit of the service node having the media contents sends reorienting information including media unit address information in the service node able to provide the terminal with the corresponding media service; F. the terminal sends service request to the media unit above.

Description

technical field

[0001] The invention relates to a content distribution network system and a content and service scheduling method thereof. Background technique

[0002] At present, the IPTV system and the distributed streaming media system generally adopt a system construction scheme based on a traditional CDN (Content Delivery Network, content distribution network) plus clustered streaming media servers. The traditional CDN organizes media nodes according to a tree structure. The transmission direction of media is one-way transmission from upper-level nodes to lower-level nodes. Media storage means that the root node stores all content, and the content stored in the parent node includes all child nodes. content; media service positioning is generally carried out layer by layer from top to bottom, and the service is provided by the lower-level node closest to the user that has content. Therefore, the more content contained in the system and the greater the number of users, ...
