Abstract
A system and method of using a multi-layered network model for analyzing the survivability of network services. The model is defined in terms of layers, connections, entities, physical processing elements, physical network elements, and physical infrastructure elements. Network services are modeled by sets of communicating entities at the application layer that are connected by connections at the underlying layers. The generality of the model constructs enable the construction of models of complex networks and services that can involve multiple layers of communication protocols, network elements, processing elements, and failover/backup mechanisms. The service survivability of a network is analyzed by projecting the failure of a set of physical elements onto the model and then determining the proportion of service affected at the application layer.
