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 of managing lip synchronization error in a multimedia content delivery network includes identifying a video packet and an audio packet associated with the video packet and determining a synchronization offset between the audio and video packets at a first monitoring point in the network. The audio and video packets are then detected at a second monitoring point in the network and a second synchronization offset is determined. When a delta between the first synchronization offset and the second synchronization offset exceeds a threshold, lip synchronization error information may be automatically recorded and/or reported to a service provider and corrective action may be taken if potential sources of the lip synchronization error are within the domain of the service provider. The video packet may be identified by a timestamp within the packet and the audio packet may be identified by audio data within the audio packet.
