Arrangement for controlling content distribution by dynamically controlling bandwidth for transfer of the content based on content authorization

摘要

A broadband network device is configured, in a broadband network, for dynamically controlling an upstream link bandwidth of a user node configured for downloading content via a downstream link having a prescribed bandwidth and uploading content through the broadband network via an upstream link according to the upstream link bandwidth. The broadband network device sets the upstream link bandwidth to a bandwidth value optimized for minimal-size data (e.g., message-based) transfers and that substantially restricts transfers of media-based (e.g., digital video or audio) data transfers to substantially long time intervals. The broadband network device is configured for dynamically increasing the upstream link bandwidth to an increased bandwidth value optimized for media-based data transfers, based on an identified authorization. The authorization may be supplied externally, for example, by a content provider, or based on a verification supplied by an authorization server that the user node is authorized to redistribute the content. Hence, content distribution can be controlled based on dynamically controlling the upstream link bandwidth according to content authorization, substantially minimizing the occurrences of unauthorized content redistribution.
