Patent ID: 8654670

Claim:
A method for determining an end-to-end measure of quality for a service provided in a packet-switched network, comprising: obtaining, by a server, network measurement data for network components within the packet-switched network utilized to provide the service; acquiring, by the server, network estimation data for an access network and an access link outside of the packet-switched network, wherein the network estimation data is directly obtained by network probes sent from the packet-switched network, wherein the network probes comprise time stamped requests used to measure a tendency of the access network to exhibit jitter and to estimate characteristics of the access links including a bandwidth capacity; and calculating, by the server, the end-to-end measure of quality for the service from the network measurement data and the network estimation data, wherein the calculating comprises: conducting reliability estimates for the access network and the access link utilizing the network estimation data; and processing the network measurement data and the reliability estimates to derive the end-to-end measure of quality.
