Szukana fraza: [Opis = "In this paper we address a new hierarchical multicriteria routing model associated with a two\-path traffic splitting routing method in MPLS networks whereby the bandwidth required by a given node\-to\-node traffic flow is divided by two disjoint paths. The model has two levels of objective functions and several constraints. An algorithmic approach is presented for calculating non\-dominated solutions and selecting good compromise solutions to this problem. Also a number of computational experiments are presented."]
