Outlines aggregation components, which process and consolidate network data from multiple sources to build comprehensive network models.
This section describes the roles and functions of the Delta Aggregation Rules Engine (DARE) and the Simple Aggregation Engine (SAgE) in Cisco Crosswork Planning.
The aggregation engines consolidate network data collected from various sources to generate comprehensive network models.
Delta Aggregation Rules Engine (DARE)
The DARE aggregator is a Cisco Crosswork Planning component that brings together various collectors, selects model information from each of them, and consolidates the information into a single model. It primarily consolidates all topology collectors' data.
Simple Aggregation Engine (SAgE)
The SAgE aggregator is a Cisco Crosswork Planning component which consolidates all the network information such as traffic, inventory, layout, multicast, NetFlow, and demands. It aggregates these changes along with the topology changes from DARE network into the final network.
SAgE aggregator enables running traffic collection, inventory collection, layout, and so on in parallel.
By default, all collectors are included in the aggregation during collection configuration. You can choose to exclude any collector from aggregation while scheduling the collection. For details, see Aggregate collector outputs.
Generation of network models
Network models are generated on completion of each level of aggregation. The first model is generated as the output of DARE aggregation. This file serves as a data source for components such as traffic, inventory, layout, NetFlow, and demands. Once the SAgE aggregation is complete, it generates the second file, the network model, which is the final output of the aggregated data collected.
