Abstract
A process for routing virtual links in a frame-switching network including a plurality of source and/or destination terminals of the frames, in which frame switches are connected to one another by physical connections, with each virtual link being defined, for a point-to-point type, by a path through the network between a source terminal and a destination terminal, and, for a multipoint type, by a plurality of paths through the network between a source terminal and a plurality of destination terminals. The process performs the routing of links by minimizing at least one cost function on a set of solutions satisfying at least one predetermined topological constraint.
