USING ROUTING INFORMATION AND INTER-LAYER RELATIONSHIPS TO DETERMINE UTILIZATION IN A TRANSPORT NETWORK

Embodiments provide systems, methods, and computer program products for mapping higher-layer circuits, links, flows, and services to lower layer circuit and connection elements to determine utilization of the lower layer circuit elements based on the high-layer traffic. Higher layer configuration data and lower layer configuration data are imported to populate a model. An inter-layer relationship is either directly or indirectly mapped from the higher layers to the lower layer. Once the inter-layer relationship is established, the higher-layer circuits, links, flows, and services are inspected using the lower layer circuit and connection elements. Circuit and packet-based utilization is determined for the lower layer elements based on the higher-layer traffic flows.
