Network controllers have available to them all manner of data from the different network elements and the various network links. Techniques are presented herein that leverage that data to support a new heat map concept. The presented techniques begin with the generation of node-level heat maps and services-level heat maps. Those artifacts may be employed to study the impact of a given failure on the nodes and the services that are present in a network. The presented techniques also support the development of a network-level heat map from those artifacts. The model that is supported by the presented techniques is common and a controller may effectively trigger the generation of a heat map for anything that a user may select. The end outcomes may include, among other things, an optimization or any goal which enables fine tuning according to an Internet service provider (ISP) or data center (DC) operator’s choice.
