Abstract
A method and system for monitoring traffic flow includes assigning a subset of sampling points to a node or unique pair of nodes. The sampling points are determined to be the most likely to monitor data traffic, and preferably all data traffic, associated with the node or node pair. The sampling point subset may automatically be determined and assigned to the node or node pair, based, for example, on historical traffic within the network. The method further includes collecting diagnostic network traffic data from the sampling points, and obtaining sampled traffic flow counts for a flow associated with a node pair from the diagnostic traffic data collected from the sampling points assigned to the source and destination nodes of the node pair. The method further includes performing a function on the sampled traffic flow counts to obtain an estimated traffic flow count for the respective flow.
