Title:
コンテンツ配信ポイントから利用可能な情報を制御するための方法および機器
Document Type and Number:
Japanese Patent JP4940454
Kind Code:
B2
Abstract:
The invention includes a method and apparatus for controlling information available at a network element located at a first hierarchical level in a content distribution network. A method includes determining a subset of content using content forecast information, comparing the determined subset of content to a subset of content available to the network element located at the first hierarchical level, generating a request adapted for modifying the available subset of content in response to a difference between the determined and available subsets of content, and propagating the request toward a network element at a second hierarchical level in the content distribution network, where the first and second hierarchical levels are different. The content may include any information adapted for being distributed from a server to a subscriber terminal (e.g., broadcast multimedia content, content-on-demand, non-streaming content such as files and software patches, and the like, as well as various combinations thereof).
