Appl. No.:

12/955672

International Classification:

H04N 7/173

US Classification:

725 95, 725 97

Abstract:

A method includes receiving data identifying new media content items to be added to a media distribution system that provides media content on demand to a plurality of endpoints. The media distribution system includes a plurality of distribution nodes, and each of the distribution nodes is coupled to a subset of the endpoints. Historical demand is determined during a particular time period for existing media content items that include content available via at least one of the distribution nodes before the data was received. The method includes forecasting demand for media content items, including new media content items and existing media content items, based on the historical demand. Each media content item is assigned to, and stored at, at least one corresponding distribution node based at least partially on a cost function and the forecasted demand.

International Classification:

H04N 21/20

US Classification:

725 87

Abstract:

A method includes receiving demand information for a first segment of a media content item and receiving demand information for a second segment of the media content item. The method includes assigning the first segment to a first set of distribution nodes of a media content distribution system based at least partially on the demand information for the first segment and based at least partially on a first cost function and assigning the second segment to a second set of distribution nodes of the media content distribution system based at least partially on the demand information for the second segment and based at least partially on a second cost function. The media content distribution system includes a plurality of distribution nodes and each distribution node is configured to provide media content items to at least some of a plurality of endpoints.

Appl. No.:

12/246973

Inventors:

AARON ARCHER - Hoboken NJ, US
Shankar Krishnan - Chatham NJ, US

International Classification:

G06F 15/16

US Classification:

709227

Abstract:

A method and apparatus for providing facility location plans for a network are disclosed. For example, the method identifies a facility and a number of nearest active clients associated with a minimized cost per unit demand of connecting these clients to this facility. The method then connects the number of nearest active clients to the facility associated with the minimized cost per unit demand. In one embodiment, the method iterates this process with the remaining clients until all demands have been assigned to facilities.

US Classification:

725 95, 725 97

Abstract:

A method includes forecasting demand for media content items of a media distribution system based on historical demand information to generate forecasted demand. The method includes generating a mixed integer program model based on storage constraints of a plurality of distribution nodes of the media distribution system, bandwidth constraints of the media distribution system, and the forecasted demand. The method includes performing a Lagrangian relaxation operation using the mixed integer program model. The method includes determining values of a cost function based on a result of the Lagrangian relaxation operation. The method includes assigning each of the media content items to a corresponding distribution node of the plurality of distribution nodes based on the cost function and the forecasted demand.
