A method and apparatus for transmitting a control signal to a self organizing network controller, are disclosed. For example, the method implemented via a processor receives a change, determines whether the change to at least one network element maintains an acceptable level for one or more service quality metrics based on a predicted service quality metric calculated using a modeling function, generates a control signal based on the determining, and transmits the control signal to the self organizing network controller to cause the self organizing network controller to configure the at least one network element in a communication network in accordance with the control signal.

A system that incorporates teachings of the present disclosure may include, for example, initializing a boundary estimate for an optimization of a linear programming model describing a network of media servers for servicing requests for media content items from subscriber devices, where the boundary estimate is an estimate of an infeasible solution of the linear programming model, and calculating iteratively, using an exponential potential function, additional boundary estimates for the linear programming model, wherein the calculating resolves to an improved boundary estimate that corresponds to placement of copies of the media content items at the media servers subject to a set of constraints on storage capacity of media servers and on bandwidth for communication links in the network. Other embodiments are disclosed.

Method and apparatus for distributing media content

A system that incorporates teachings of the subject disclosure may include, for example, determining identified impressions that are detected from consumption data collected from a group of media processors where the identified impressions represent viewing of selected content and where the consumption data indicates channel tuning events at the group of media processors including changing of channels, applying a ridge regression analysis to the identified impressions to determine a predicted number of target impressions per advertisement slot, and generating a media plan based on a ratio of an advertisement slot cost to the predicted number of target impressions per advertisement slot. Other embodiments are disclosed.

Method and apparatus for managing advertising

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.

Content placement

A method of assigning a server to a client system includes determining an ingress point of the client system and identifying possible egress points for the client system. The method further includes selecting the server from a plurality of servers to reduce network cost and delivery time.

Topology aware content delivery network

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.

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.

Using video viewing patterns to determine content placement

A method and apparatus for provide highly efficient traffic routing for a wide range of possible traffic matrices (TM) in an intra-domain network. That routing optimally balances the traffic loads over a range of traffic matrices so as to minimize the deviation for any particular traffic matrix from the optimal routing. Such a routing provides a guaranteed performance ratio against the best possible network routing. The invention utilizes a method of optimally configuring a traffic network based on solving a linear program to obtain the optimal routing, and then configuring the routing on the network accordingly.
