TY - GEN A1 - Dahl, Geir A1 - Martin, Alexander A1 - Stoer, Mechthild T1 - Routing through virtual paths in layered telecommunication networks N2 - We study a network configuration problem in telecommunications where one wants to set up paths in a capacitated network to accommodate given point-to-point traffic demand. The problem is formulated as an integer linear programming model where 0-1 variables represent different paths. An associated integral polytope is studied and different classes of facets are described. These results are used in a cutting plane algorithm. Computational results for some realistic problems are reported.
