Аннотация A fault-tolerant routing model for unicast flows in MPLS-network is proposed. The flow-oriented model is represented by algebraic equations and inequalities characterizing the state of MPLS-network, i.e. load of its communication links. The proposed model includes the possibility to implement three basic backup schemes in accordance with the concept of Fast ReRoute: link, node and path protection. The model describes also three different types of condition of the links overload prevention for different variants of channel resource use. The above example demonstrates the advantages of using the proposed conditions of the links overload prevention in paper.
