Patent ID: 8280994

Claim:
A method of operating a network based on quality of experience, the method comprising the steps of: determining, by a Quality of Experience server, that a Quality of Experience (QoE) violation associated with a service has occurred; determining, by the Quality of Experience server, if the QoE violation is due to an equipment failure; if the QoE violation is not due to an equipment failure, determining, by the Quality of Experience server, if the QoE violation is due to violation of an individual nodal Quality of Service (QoS) requirement by a node on the network, the individual nodal QoS requirement specifying how the node is required to operate to enable the service to be implemented on a network path through the network to enable the node to satisfy specified QoE requirements for the service; and if there has been a nodal QoS violation, performing, by the Quality of Experience server, nodal optimization to adjust the manner in which the node is handling traffic to attempt to meet the QoS requirements; if there has not been a nodal QoS violation, adjusting, by the Quality of Experience server, a class of service mapping for the service or identifying and selecting application layer control knobs for the service to enable the network to be adjusted to enable the Quality of Experience requirements for the service to be satisfied.
