    摘要： 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.

    摘要： A method and apparatus for providing trouble isolation for a Permanent Virtual Circuit (PVC) on packet networks are disclosed. For example, the method receives an alert or a ticket for a Permanent Virtual Circuit (PVC) down or a PVC degraded and starts a correlation window for said PVC and port alert or ticket. The method then gathers a plurality of port and PVC alerts for a duration of said correlation window and determines whether or not a port down or a port degraded alert is received along with a PVC down or a PVC degraded alert in said correlation window for one or more ports associated with said PVC.

    摘要： 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.

    摘要： 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.
