Patent number: 11595308Abstract: A system for closed loop prefix management for white boxes includes a network device, a route reflector coupled to the network device, a software defined network controller coupled to the route reflector and the network device, and a prefix usage analyzer in the software defined network controller. The prefix usage analyzer determines usage attributes of prefixes and identifies the prefixes with a predetermined usage attribute. The software defined network controller instructs a network controller in the network device to store the prefixes with the predetermined usage attributes in a table in the network device.Type: GrantFiled: June 13, 2019Date of Patent: February 28, 2023Assignee: AT&T Intellectual Property I, L.P.Inventors: Yaron Koral, Steven A.

Patent number: 11488722Abstract: Systems and methods mediate anomaly notifications in health data to health alerts using data structures and logic to organize, contain, and dispose of identified health anomalies. Multiple detection algorithms, operating asynchronously and independently, run against one or more health data streams. Examples of data streams are electronic laboratory requisitions and results, OTC sales of medicines and medical supplies, emergency department visit data, and others. The outputs of anomaly detection generators—anomaly notifications (anomalies)—are processed by the invention. The case manager organizes anomaly notifications and supports collaborative decision making and disposition among expert users.Type: GrantFiled: April 18, 2019Date of Patent: November 1, 2022Assignee: AT&T Intellectual Property II, L.P.Inventors: Colin Goodall, Guy Jacobson, Simon Tse, John Mark F.

Patent number: 11329751Abstract: Devices, computer-readable media and methods are disclosed for verifying that an optical transmit/receive device is correctly installed. For example, a processing system including at least one processor may activate a first light source of an optical transmit/receive device of a telecommunication network and detect a receiving of a light from the first light source at a port of an optical add/drop multiplexer of the telecommunication network. The processing system may then verify the optical transmit/receive device and the port of the optical add/drop multiplexer match a network provisioning order, when the receiving of the light from the first light source is detected, and may generate an indication that the optical transmit/receive device is correctly installed, when the optical transmit/receive device and the port of the optical add/drop multiplexer match the network provisioning order.Type: GrantFiled: May 17, 2021Date of Patent: May 10, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Simon Tse, Martin Birk, Shweta Vachhani, Kathleen Tse
