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.

摘要： A method and an apparatus for detection and prevention of a slow response on a network are disclosed. For example, the method selects a router automatically for testing in response to a ticket indicating a slow response, and performs a diagnostic test on the router, wherein the diagnostic test comprises at least one of: a protocol diagnostic test, a circuit diagnostic test or, a congestion diagnostic test. The method then performs at least one remedial step to address a root cause that is identified by the diagnostic test, wherein the root cause is associated with the slow response.
