Cyber Resilience Approach Based on Traffic Engineering Fast ReRoute with Policing

The paper is devoted to the research and development of the cyber resilience ensuring approach based on Traffic Engineering Fast ReRoute with the support of Traffic Policing features. The basis of the proposed approach is the mathematical model presented by the conditions of multipath routing, modified conditions of the flow conservation. It also takes into account traffic policing on the network edge, as well as conditions for protecting (reserving) the link, node, and network bandwidth adapted to cyber resilience requirements. The advantage of the proposed solution is problem formulation as a linear optimization. In the numerical example, the operability of the model and the adequacy of the results obtained on its basis have been demonstrated.
