Abstract:
1. A method for analyzing traffic flow in a modeled network, comprising: defining a plurality of traffic flows, each traffic flow of the plurality of traffic flows corresponding to a path from a source node to a destination node in the modeled network, generating a plurality of streams of tracers, each stream of tracers being associated with one traffic flow of the plurality of traffic flows, and each tracer of each stream of tracers being structured to contain flow information related to the traffic flow corresponding to the tracer, propagating each tracer through the modeled network along the path from the source node to the destination node of the tracer's corresponding traffic flow, and updating the flow information in each tracer based on changes to the tracer's corresponding traffic flow introduced by nodes in the modeled network along the path from the source node to the destination node of the tracer's corresponding traffic flow.
