Abstract

A flow-based model of fault-tolerant routing with path protection has been improved. In the course of the improvement, when the fault-tolerant routing problem was presented in optimization form, an optimality criterion has been formulated, which contains the conditions for path protection when it is possible to implement both single path and multipath routing strategies. The novelty of the proposed improvement lies in the fact that the path protection conditions are included in the optimality criterion in bilinear form. The efficiency and adequacy of the proposed improvement of the flow-based model of fault-tolerant routing has been confirmed in a number of computational examples in solving single path and multipath routing problems when implementing the path protection scheme in the network.
