Abstract
A method and network management node for determining the managed nodes on a path from a given source node to a given destination node based on a statistical inference of traffic volume reports available from the nodes. Traffic counts from Performance Management (PM) counters are collected from all managed transport nodes including the source and destination nodes. Based on the observed pattern of traffic volume received from the PM counters, the most likely matching path from a given source to a given destination is selected. If the traffic counts are insufficient to establish a path with adequate certainty, the method may optionally generate additional traffic from the source node to the destination node to increase the reliability of the path determination.
