IMPAIRMENT DETECTION AND RECORDING OF ISOCHRONOUS MEDIA STREAMS

摘要

This invention relates to a capturing scheme for the storing packets of isochronous, real-time packets streams in response to a trigger condition. The invention is suggesting a non-intrusive, passive monitoring solution for monitoring isochronous real-time traffic, which is allowing for an economic capturing of packets and can be implemented on standard server hardware. The invention is using a real-time impairment analysis run on impairment intervals, and a per-session or per-packet stream impairment interval-based packet capturing in response to a capturing trigger firing. One or more triggers can be defined based on various metrics either obtained from the packets of the packet streams or defined by the operator.
