Claim Text:
1. A method in a network management node for determining a path followed by traffic through a communication network between a source node and a destination node, wherein the communication network includes a plurality of intermediate nodes, and the traffic passes through at least one of the intermediate nodes between the source and destination nodes, the method comprising: collecting by a path analysis unit, traffic-volume information from the source node, the plurality of intermediate nodes, and the destination node; determining by the path analysis unit, a best matching path utilizing a statistical inference from the collected traffic-volume information; determining whether sufficient traffic-volume information was collected for the statistical inference to be reliable; and updating path information with the best matching path when sufficient traffic-volume information was collected for the statistical inference to be reliable; when sufficient traffic-volume information was not collected for the statistical inference to be reliable:
