The node and link protection were formulated in the linear form with implantation of the single path and multipath routing strategies. The linear-quadratic criterion of optimality was justified. With the aim to ensure a maximum network performance and solution scalability the system of hierarchy relations was determined. The efficiency and adequacy of the proposed fast reroute model were confirmed by a number of numerical examples for solving the single path and multipath routing problems using the implementation of various protection schemes of the network elements. %8 2017-08-28
