Zusammenfassung:	A method (100) for routing packets in a communication network (10) having a variable and predictable topology. The network includes a plurality of nodes, and each node can be connected, at least temporarily, to one or more other nodes in the network. The packets are transmitted from a source node (21) to a destination node (23). An orchestration entity (25) determines (101) a plurality of temporary paths (31) between the source node and the destination node for several successive time periods (Pi), the existence of a temporary path being guaranteed for the time period with which it is associated. The orchestration entity (25) generates (102) a table (T) of label stacks (LSi), in which table each label stack corresponds to the temporary path defined for one of the successive time periods, and each label (Lj, i) corresponds to a node of the temporary path.
