Abstract
A method a system of identifying and determining degradation of the quality of service (QoS) perceived by a subscriber in a network such as the Internet. Traffic of individual applications of the subscriber and aggregate traffic of a subscriber are monitored, captured, and processed to produce QoS statistics. End-to-end QoS metrics are provided for TCP connections based on the observation of packet flows at a single monitoring point. The QoS metrics include, for example, packet loss internally and externally to the monitoring point, detection of stalled periods and estimation of path delay.
