The work is devoted to the design and research of the mathematical model for Secure Traffic Engineering Fast ReRoute under Traffic Policing (Secure TE-FRR-TP) approach. The task of the Secure TE-FRR-TP was presented in the optimization form where the novelty of the flow-based model is concerned with the enhancement of load balancing conditions and bandwidth protection during fast rerouting that also considers the compromise probability of network links. The model analysis has been conducted and the main features of the Secure TE-FRR-TP have been explained. Additionally, the comparison of routing solutions with different parameters of the functional dependence of weighting coefficients in load balancing condition on the probability of compromise has been performed, which has shown that sensitivity of routing solutions to the values of probabilities of the link compromise was regulated by the choice of this model parameters.
