摘要： A method and system for publication control of digital content for validating the rights information registered by a plurality of separate content providers. When receiving a digital content publication application from a content publication unit, a publication control unit queries whether rights information corresponding to the digital content to be published is stored in a rights publication unit, and if stored, allows the publication of the digital content and of a download address thereof. By messaging rights information in this centralized manner, it may be ensured that a content buyer can efficiently obtain the rights object distributed after the digital content is published.

摘要： A method for distributing file data includes: obtaining a first request message of a first client for downloading a first file, and determining an autonomous system (AS) where the first client is located; searching the AS for edge servers that support peer to peer (ES-Ps), and returning the address of at least one ES-P storing the first file to the first client; and sending the first file stored in the ES-P to the first client according to the client information returned by the ES-P. Related devices and systems are also provided. The present invention may speed up the file data distribution, reduce the restriction of the file data distribution due to fixed bandwidth of the ES, and enable P2P data streams to be converged into an AS, thus reducing the impact on backbone networks.
