Resilience will be an essential design and operational characteristic of future networks. This paper first surveys resilient networks and Situation Awareness (SA) in cyberspace. Then, SA is introduced in the detection module development of the authors' dynamic adaptation architecture that realizes the resilience control loop. Finally, a state transition model based on Petri net analyzing resilience is presented. Further detailed development including a fusion algorithm to analyze failure based on SA and state transition according to failure model evaluating resilience forms the basis for further work.
