  • Patent number: 7313736
    Abstract: A distributed method and system of controlling a communications network having a plurality of spans of interconnected network elements some of which include a network element processor distributes network topology information to respective span databases; stores original fault objects in the respective span databases; advertises fault objects to other network element processors in a local span when the original fault affects network elements other than a network element in which the fault occurred; advertises alarm objects to other network element processors that are respectively associated with a circuit affected by the original faults; stores the advertised fault and alarm objects in the respective span databases; and performs distributed processing of the advertised fault and alarm objects with the other network element processors and the respective span databases.

  • Patent number: 7181141
    Abstract: An exemplary embodiment of the invention is a network element in an optical communications network. The network element includes a data collection application program interface (API) for receiving a request from a client for network topology information along with a topology gatherer module, a topology change module and a gateway node module, each in communication with the data collection API. One of the topology gatherer module, topology change module and gateway node module provides the network topology information requested by the client to the data collection API. The data collection API then provides the network topology information to the client. Alternate embodiments include a method of collecting optical communications network.

  • Patent number: 6694455
    Abstract: A distributed method and system of controlling a communications network having spans of interconnected network elements that distribute network topology information to respective span databases; advertise fault objects to other network elements in a local span when the original fault affects network elements; advertise alarm objects to other network elements that are respectively associated with a circuit affected by the original fault; and perform distributed processing of the advertised fault and alarm objects with the other network elements and the respective span databases. Other faults and alarms that may exist on the network are aggregated. Causality may be determined by correlating other faults and alarms with the received fault. Sympathetic faults are suppressed while root cause faults are promoted to an alarm and reported to affected network elements. The number of alarms viewed by a network manager are reduced by performing such distributed alarm correlation and fault reporting suppression.
