摘要：A packetized streaming media delivery network carries many “streams” ofdiffering media content. They often are from multiple sources and of different mediatypes. The invention consists of a scalable hardware and/or software computing elementresolving the network traffic into its individual streams for focused, simultaneous, andcontinuous real-time monitoring and analysis. The monitoring and analysis consists ofdelay factor and media loss rate which measure the cumulative jitter of the streamingmedia within the delivery network and the condition of the media payload. Thesemeasurements form a powerful picture of network problem awareness and resolution.The delay factor objectively indicates the contribution of the network devices in thestreams' path, allowing for both problem prediction and indication. In one example,tapping a packetized network at various locations allows for correlation of the same-stream performance at various network points to pinpoint the source(s) of theimpairment(s).
