A network device is described that receives information from separate database systems including a physical network inventory system that stores first topology data specifying resources and links within a network and a traffic engineering system that stores second topology data specifying the resources and links that are deployed within the network and data specifying traffic engineered paths configured to forward network traffic through the network. The network device aggregates the received information into a topology resource management system that stores third topology data specifying at least a current role of each of the resources and links. The network device determines a modification to at least one of the traffic engineered paths based on the third topology data, including an adjustment to the current role of at least one of the resources to change the forwarding of the network traffic. The network device outputs provisioning information based on the modification.
