Abstract: The invention relates to a method of routing in a network. The network consists of a plurality of network nodes. The network may have different interlinks and connections from one network node to the others. An actual topology for the network is thus created. According to the invention, the routing is performed in two phases. First, the number of possible links to the network nodes is reduced in a reduction phase. A reduced topology is thus created in which network nodes or links to network nodes that are not required for route finding are discarded. In a subsequent routing and time planning phase, an optimized route to a network node in the reduced topology is then calculated.
