Abstract: In a voice-over-IP communications network, call data records include dynamically assigned IP signaling addresses such as IPv6 signaling addresses used in provisioning communications sessions. Those dynamically assigned IP signaling addresses are computed from customer site identification codes using a reversible algorithm. The algorithm can then be reversed to compute a customer site identification code from an IP signaling address contained in a call data record, allowing the communications network provider to perform quality monitoring and diagnostics based on call data records.

Abstract: A method and apparatus for providing asynchronous alarm correlation in packet networks are disclosed. For example, the method receives a trigger, and performs an asynchronous correlation of at least one root cause alarm with at least one symptom alarm.

Abstract: Systems and methods are described that vertically integrate telecommunications network management across multiple transport domains and network layers to support E2E network management. Embodiments vertically integrate telecommunications network management across multiple transport layers such as physical layers (optical), data link layers (Ethernet), and upper layers (VLAN), and establish an inventory database for the plurality of transport layers in a network management OSS to integrate and correlate network alarms and other business applications. Embodiments provide a single platform for an E2E network management solution across and for multiple transport domains.

Abstract: A method is provided for monitoring devices with changing IP addresses. SNMP trap is received from a device at a first IP address to notify that a connection is up, and a SNMP poll is transmitted to the device to obtain an identifier. Predetermined consecutive SNMP GET requests are transmitted to the device in intervals. Responsive to failing to receive from the device predetermined consecutive SNMP GET responses equal to the predetermined consecutive SNMP GET requests, it is determined that there is a connection failure or a device failure and checked whether the device is in a maintenance window. If not in maintenance window, a trouble ticket is generated. Responsive to the failure, there is a predetermined waiting period for another SNMP trap from the device with a second IP address and the same identifier notifying that a connection is back up, and no trouble ticket is generated.

Abstract: A method for managing tie-down information in a network management system for a telecommunications network including: providing tie-down information to the network management system associated with a plurality of tie-down demarcations using a tie-down information template comprising a plurality of tie-down information parameters associated with each of the plurality of tie-down demarcations, wherein the plurality of tie-down information parameters comprises a status; and updating the status associated with each of the plurality of tie-down demarcations based on network activity associated with the plurality of tie-down demarcations.

Abstract: A method and apparatus for monitoring of a network device are disclosed. For example, the method receives a monitoring record from a network device, and determines whether the network device is listed in an active pool of monitored network devices. The method then automatically enables the monitoring of the network device if the network device is not listed in the active pool of monitored network devices.

Abstract: A method and apparatus for managing customer topologies on packet networks are disclosed. For example, the method creates at least two event correlation instances for at least one customer topology, where a first event correlation instance resides in a primary availability management server, and a second event correlation instance resides in a secondary availability management server. The method also creates a test node for the first event correlation instance, where the test node provides at least one test message. The method then receives at least one response generated by the first event correlation instance that is responsive to the at least one test message, where the at least one response is received by the second event correlation instance. The method then performs a fail-over to the second event correlation instance from the first event correlation instance if a failure is detected from the at least one response.

Abstract: A method and apparatus for managing networks across multiple domains are disclosed. For example, the method stores a mapping table that correlates one or more Customer Edge Routers (CERs) with one or more Route Processing Modules (RPMs) in at least one seed-file distributor, where each of the one or more Customer Edge Routers (CERs) is monitored by one of the at least one availability manager. The method receives an alarm associated with one of the one or more RPMs that affects one of the one or more CERs, where the alarm is received by one of the at least one availability manager that is monitoring the affected one of the one or more CERs. The method then provides a status associated with the one of said one or more RPMs in accordance with the alarm.

Abstract: The present invention provides a method and system for automatically providing infrastructure maintenance for a customer in response to a customer form/report/ticket in a communications network that includes a core communications (voice and data communications) service and an Access Provider service. Typically, the system includes a Work-Flow Manager and a maintenance program scheduler. The Work-Flow Manager is arranged to trigger, for each customer form/report/ticket, each automatic software program/engine of a plurality of automatic software programs/engines in response to an associated milestone event for the customer form/report/ticket. The maintenance program scheduler is coupled to the Work-Flow Manager and is used for invoking at least one predetermined maintenance software program based upon predetermined criteria being met by the form/report/ticket.

Abstract: A restoration system is provided for enhancing the reliability of a telecommunications network such that particular traffic which is disrupted by, for example, a faulty link, may be quickly rerouted via an alternate route established "on the fly". In particular, each node and link forming the network is monitored, and in the event that such monitoring detects a faulty link or node then a central controller is notified. The controller is arranged to locate spare capacity and establish an alternate route, in which the continuity of the alternate route is confirmed before the disrupted traffic is transferred thereto.
