Data processing stage
Topology deduction takes place during the data processing stage, as the information from the data collection stage is analyzed, interpreted and processed by the stitchers. The culmination of the data processing stage is the production of the containment model.
The data processing stage corresponds to creating the topology. This is the final conceptual step in the discovery cycle.
The data processing and data collection stages usually overlap, because you can configure the stitchers to begin processing connectivity information from different discovery agents before the main stitching operation begins.
