20080259805 | METHOD AND APPARATUS FOR MANAGING NETWORKS ACROSS MULTIPLE DOMAINS - 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. | 10-23-2008 |
20100052924 | Method and System for Detecting and Managing a Fault Alarm Storm - A method and system of managing network alarms including associating an alarm type with a plurality of network alarms using information associated with the plurality of network alarms, the information comprising a quantity of the plurality of network alarms and a cause of the network alarms; and processing the plurality of network alarms based on the alarm type associated therewith. | 03-04-2010 |
20100080115 | METHODS AND APPARATUS TO MONITOR BORDER GATEWAY PROTOCOL SESSIONS - Example methods and apparatus to monitor border gateway protocol sessions are disclosed. A disclosed example method includes detecting a failure of a first border gateway protocol (BGP) session and initiating a session-down timer in response to detecting the failure. The example method also includes generating a sustained-down alarm when a threshold time value of the session-down timer is exceeded before the first BGP session is re-established. | 04-01-2010 |
20100124165 | Silent Failure Identification and Trouble Diagnosis - According to one method for identifying and resolving a silent failure in a telecommunications network, performance data associated with data traffic passing through a network element in the telecommunications network is collected. A determination is made whether the performance data has fallen below a threshold to identify the silent failure at the network element. The silent failure fails to trigger an alarm included on the network element. Responsive to determining that the performance data is below the threshold and thereby identifying the silent failure at the network element, troubleshooting rules may be retrieved. The silent failure is resolved based on the performance data and the troubleshooting rules. | 05-20-2010 |
20110141914 | Systems and Methods for Providing Ethernet Service Circuit Management - Methods and systems for providing Ethernet service circuit management are disclosed. A system includes a network and a root cause analysis system (RCAS). Device, link, and network topologies are developed for all devices in the network and are stored at a desired data storage location. When an alarm is received by the RCAS, the RCAS retrieves the device, link, and network topologies, and performs a root cause analysis based upon the topologies and one or more rules. Depending upon the outcome of the root cause analysis, some alarms may be consolidated, suppressed, and/or reported to the appropriate network personnel. | 06-16-2011 |
20120030523 | Alarm Threshold For BGP Flapping Detection - Methods and systems are described that improve the alarming logic for Border Gateway Protocol (BGP) flapping events. Embodiments provide an alarm threshold on BGP flapping conditions and alert on BGP related events. A reduction in silent failures and network outage minutes is achieved. | 02-02-2012 |
20120155321 | METHOD AND APPARATUS FOR PROVIDING LONG TERM EVOLUTION NETWORK TOPOLOGY MANAGEMENT - A method and apparatus providing a network topology management of a wireless communication network are disclosed. The method discovers network topology data of the wireless communication network, wherein the wireless communication network comprises a self-healing capability, and identifies a difference between the network topology data that is discovered against a stored network topology data of the wireless communication network. The method updates the stored network topology data with the difference that is identified. | 06-21-2012 |
20120213091 | METHODS AND APPARATUS TO MONITOR BORDER GATEWAY PROTOCOL SESSIONS - Example methods and apparatus to monitor border gateway protocol sessions are disclosed. A disclosed example method includes detecting a failure of a first BGP session, initiating a sustained-down timer and a reset-timer in response to detecting the failure, identifying a sustained-down condition in response to the sustained-down timer exceeding a first time threshold, identifying a flapping condition in response to counting a threshold number of BGP failures and corresponding BGP re-establishments during a second time threshold of the reset-timer, and identifying a continuous flapping condition in response to detecting the flapping condition consecutively for a threshold number of instances. | 08-23-2012 |
20120327776 | Alarm Threshold For BGP Flapping Detection - Methods and systems are described that improve the alarming logic for Border Gateway Protocol (BGP) flapping events. Embodiments provide an alarm threshold on BGP flapping conditions and alert on BGP related events. A reduction in silent failures and network outage minutes is achieved. | 12-27-2012 |
