Patent number: 7313736Abstract: 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.Type: GrantFiled: June 14, 2004Date of Patent: December 25, 2007Assignee: Ciena CorporationInventors: Clark Scrandis, Michael B.

Patent number: 7039312Abstract: The present invention is directed toward a distributed intelligence fiber-optic communication network in which node control processors (NCPs) associated with each network element periodically transmit identification and status information to the other NCPs in the network. Various faults in the network can thus be readily identified, and appropriate tasks for modifying the network in response to the fault (such as rerouting around a defective network element) can be carried out. Further, information continues to be distributed among the NCPs even if a break occurs in a segment of fiber in the network.Type: GrantFiled: June 13, 2002Date of Patent: May 2, 2006Assignee: Ciena CorpInventors: Keith A. Condict, Stephen R. Harmon, Wesley R. Jones, Michael B. Peters-Rodbell

Patent number: 6807523Abstract: A method and system for emulating the optical behavior of an optical communications generates wavelength modeled objects for each emulated optical signal and a variety of other modeled objects for the optical communications modules of the emulated system such as transmitter modeled objects, a combiner modeled object, an amplifier modeled object, a splitter modeled object, and receiver modeled objects. Each of the modeled objects includes certain optical attributes and a behavior modeling function particular to the module being emulated. The optical modules themselves are also represented as emulated processes. The modeled objects are propagated along a logical path from emulated process to emulated process. Upon receipt of a modeled object the emulated process executes the behavior modeling function and updates modeling objects affected by the execution.Type: GrantFiled: October 31, 2001Date of Patent: October 19, 2004Assignee: Ciena CorporationInventors: James B.

Patent number: 6694455Abstract: 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.Type: GrantFiled: July 27, 2000Date of Patent: February 17, 2004Assignee: Ciena CorporationInventors: Clark Scrandis, Michael B.
