Forwarding quality control method in data network, involves detecting potentially overload paths or individual out-interfaces to select nodes for measurement, and measuring quality metrics of selected nodes

摘要

The method involves detecting potentially overloaded paths or individual out-interfaces by combining the end-to-end measurements and information of network routing topology. The nodes for measurement are selected based on the detected paths or interfaces. The quality metrics of the selected nodes are measured. An independent claim is also included for a node in the data network.
