The product is split between two major sub-products:
iDiscover
Discovers IP network infrastructure and uploads it into an network inventory model. The data in the model is captured automatically and dynamically through a flow of several information (document) xslt transformations.
iTopoManager
Provides an GUI interface that will help you reason about your network and take decisions what to do with it. Once you have the knowledge about what has to be done iTransformer will help you to apply the change.
