    摘要： Methods and apparatus to detect and restore flapping circuits in IP aggregation network environments are disclosed herein. An example method for use in maintaining a communication network includes retrieving information related to an operating state of a device associated with a network disturbance; determining whether the information related to the operating state of the device is indicative of a flapping condition; when the operating state information indicates that the flapping condition is present in the network, determining a cause of the flapping condition; when the cause of the flapping condition is a physical cause, selecting a first recovery procedure; and when the cause of the flapping condition is a logical cause, selecting a second recovery procedure different from the first recovery procedure.

    摘要： A computer-implemented method includes receiving, at a monitoring center of a media distribution network, from a set top box device associated with a customer account, first error data indicating occurrence of a first error at the set top box device at a first time. The set top box device is at least partially functional after occurrence of the first error. The computer-implemented method includes receiving, at the monitoring center, second error data indicating occurrence of a second error at the set top box device at a second time. The set top box device is at least partially functional after occurrence of the second error. The computer-implemented method includes determining an elapsed time between the first time and the second time. The computer-implemented method includes automatically generating a trouble ticket indicating failure of the set top box device when the elapsed time satisfies a first threshold.

    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： Computer systems and techniques for predicting a cable failure in a network system begin by receiving a remote alarm indicator followed by a remote alarm indicator clear as a transmission alarm indicator of an intermittent short duration failure on the transmission path of a circuit. If the transmission alarm indicator is of a duration less than or equal to a preset threshold D it is considered an acceptable short hit transmission alarm. When at least N acceptable transmission alarms have been received and the time stamps of the last N acceptable transmission alarms have been recorded, then a determination is made as to whether N acceptable transmission alarms have been received within a preset time period. A moving window time period is calculated as the difference between the time stamp of the present acceptable transmission alarm K and the time stamp of the [(K−N)+1] acceptable transmission alarm. If the difference is less than or equal to T, a cable error signature is indicated. Based on the cable error signature, a cable failure may be predicted.
