Publication number: 20240146436Abstract: The concepts and technologies disclosed herein are directed to alarm correlation and ticketing for reconfigurable optical add/drop multiplexer (“ROADM”) networks. According to one aspect disclosed herein, a ROADM controller can create, based upon data associated with a plurality of ROADM network elements operating in a ROADM network, a graph of the plurality ROADM network elements. The ROADM controller can retrieve a plurality of alarms from at least a portion the plurality of ROADM network elements, associate the plurality of alarms with at least the portion of the plurality of ROADM network elements, and associate a direction of each alarm with a corresponding service direction. The ROADM controller can eliminate any alarms with a time stamp outside of a same time window. The ROADM controller can then determine that any remaining alarms are associated with a root cause of a failure within the ROADM network.Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Applicant: AT&T Intellectual Property I, L.P.Inventors: Qingyun Liu, Balagangadhar Bathula

Publication number: 20230134574Abstract: A multi-layer network planning system can determine a set of regenerator sites (“RSs”) that have been found to cover all paths among a set of nodes of an optical layer of a multi-layer network and can determine a set of candidate RSs in the optical layer for use by the links between a set of nodes of an upper layer, wherein each RS can be selected as a candidate RS for the links. The system can determine a binary path matrix for the links between the set of nodes of the upper layer. The system can determine a min-cost matrix that includes a plurality of min-cost paths. The system can determine a best RS from the set of candidate RSs and can move the best RS from the set of candidate RSs into the set of RSs for the links. The system can then update the binary path matrix.Type: ApplicationFiled: December 29, 2022Publication date: May 4, 2023Applicant: AT&T Intellectual Property I, L.P.Inventors: Balagangadhar Bathula, Angela Chiu, Rakesh Sinha, Sheryl Leigh Woodward

Patent number: 11349566Abstract: Devices, computer-readable media and methods are disclosed for determining reachability for a wavelength connection in a telecommunication network. For example, a processor deployed in a telecommunication network may calculate a fiber loss on a link in the telecommunication network using optical power measurements and determine that a destination node of a wavelength connection is not reachable via a path that includes the link based upon the fiber loss of the link that is calculated. In one example, the determining is based upon a number of links in the path, an effective fiber loss for each link in the path, a penalty for nodes in the path, and an acceptable loss value. The processor may further perform a remedial action in response to determining that the destination node of the wavelength connection is not reachable via the path.Type: GrantFiled: November 30, 2020Date of Patent: May 31, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Sheryl Woodward, Kathleen Tse, Martin Birk, Angela Chiu, Balagangadhar Bathula
