    摘要： 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.

    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 includes automatically correlating indicators already generated by network components to detect and isolate failures that are caused by or related to network components operating on different layers of the open system interconnect (OSI) model. Failure indicators that persist for longer than a specified time window are automatically detected and correlated with one another based on a topology table. The method uses indicators already generated by the network components, obviating the need for software that typically resides on and consumes valuable processing time of network components.

    摘要： A method of determining a path through a network. Structures in a network are grouped into structure groups, each structure group comprising at least two nodes. Virtual circuit information for every pair of nodes in the structure groups is determined, and connections between the structure groups is determined. A least cost path is determined from a first node to a second node using the virtual circuit information and connection information.

    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.
