Patent number: 10834616Abstract: 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.Type: GrantFiled: February 25, 2019Date of Patent: November 10, 2020Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T MOBILITY II LLCInventors: Ajay Mahimkar, Shomik Pathak, David Lee Applegate, Sarat Puthenpura, Zihui Ge, Kurt Huber, Swati Roy

Patent number: 10447776Abstract: 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.Type: GrantFiled: February 21, 2018Date of Patent: October 15, 2019Assignee: AT&T Intellectual Property I, L.P.Inventors: Aaron Francis Archer, Seungjoon Lee, David Lee Applegate, Kadangode Ramakrishnan, Vijay Gopalakrishnan

Patent number: 8031635Abstract: 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.Type: GrantFiled: June 3, 2008Date of Patent: October 4, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: David Lee Applegate, Edith Cohen

Patent number: 7996423Abstract: In accordance with the teachings of the present invention, a method of data drilling is presented. A network database is deployed in a network, such as the Internet, for broad-based user access. Network information is stored in the network database and is organized in layers. A graphical user interface with data objects is presented to an end user. Selecting a data object generates a query performed by a server. Each query produces more details on an initially selected data object.Type: GrantFiled: November 23, 2009Date of Patent: August 9, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: David Lee Applegate, Maksym Badrak, Hossein Eslambolchi, John R.
