  • System and method for topology discovery and fiber continuity verification in network
    Patent number: 11343599
    Abstract: An optical network includes an arrangement of optical nodes. An optical node of the arrangement, and corresponding method, perform optical connectivity discovery and negotiation-less optical fiber continuity verification in the optical network. An overall topology of optical connectivity provisioned for the arrangement is discovered by the optical node based on messages received from a management network communicatively coupling the optical nodes to each other. The optical node synchronizes, temporally and sequentially, with the other optical nodes based on the messages received, assigns fiber of the overall topology, based on a verification sequencing method, to verification slots of a verification sequence, and verifies continuity of fiber according to the verification slots of the verification sequence.
    Type: Grant
    Filed: February 22, 2021
    Date of Patent: May 24, 2022
    Assignee: XIEON NETWORKS S.a.r.l.
