The research is dedicated to evaluating and developing a method for assuring cyber resilience based on Traffic Engineering Fast ReRoute with the assistance of the Traffic Policing mechanism. The suggested approach is founded on a mathematical model defined by multipath routing conditions and modified flow conservation conditions. Additionally, it considers traffic policing at the network edge and conditions for protecting (reserving) the link, node, and network bandwidth, all of which are tailored to meet cyber resilience needs. The proposed solution has the advantage of recasting the problem as a linear optimization. The numerical example demonstrates the model's operability and the adequacy of the findings acquired using it.
