Patent number: 11489715Abstract: A method for analyzing failures in network resources in a multilayered communication network using passive shared risk resource groups may include, in a processor, identifying network resources in a plurality of network resources having common risk attributes. The network resources may be grouped into one or more passive shared risk resource groups (PSRG) based on the common risk attributes. A likelihood of a PSRG failure may be assessed for each of the one or more PSRGs.Type: GrantFiled: April 11, 2019Date of Patent: November 1, 2022Assignee: SEDONASYS SYSTEMS LTDInventor: Ornan Alexander Gerstel

Patent number: 11469992Abstract: A computerized system for performing preparation operations for a maintenance activity that causes a disruption in a communication path of traffic over a multi-layer network. The system comprising: a maintenance tool configured to coordinate maintenance activities of the multi-layer network based on maintenance activity data, a storage unit to store the maintenance activity data; and a multi-layer control system comprising a processor, wherein said processor is configured to: receive from the maintenance tool an indication that one or more maintenance activities are required on an indicated optical resource, determine an affected optical path, determine an affected IP link utilizing said affected optical path; remove traffic from the affected IP link; remove the affected optical path; activate an alternative optical path; configure the packet switching layer to utilize the alternative optical path; and repeat for each affected optical path and each affected IP link.Type: GrantFiled: October 7, 2019Date of Patent: October 11, 2022Assignee: SEDONASYS SYSTEMS LTDInventor: Ornan Alexander Gerstel

Patent number: 11329862Abstract: A method for assigning a severity to failure indications of network resources in a multilayered communication network includes in a processor, receiving one or a plurality of failure indications related to a failure of one or more network resources from a plurality of network resources in a communication network. A severity may be assigned to the one or said plurality of failure indications based on an impact on data, wherein assigning the severity includes at least one of: assigning a static severity based on a single traffic impact assessment in the communication network due to the one or more failed network resources, and assigning a dynamic severity based on continuous or periodic traffic impact assessments in the communication network due to the one or more failed network resources. The severity of the one or said plurality of failure indications may be outputted on an output device.Type: GrantFiled: November 7, 2018Date of Patent: May 10, 2022Assignee: SEDONASYS SYSTEMS LTDInventor: Ornan Alexander Gerstel
