A system for operating a network. The system includes a processor and memory storing instructions. The instructions, when executed by the processor, cause the processor to generate a network path from a source device to a destination device. The instructions include a path calculation engine (PCE) configured to select, from the network, a first intervening device for connecting the source device and the destination device to form the network path, further select, from the network and as additional candidates to form the network path, a first plurality of candidate devices to be in the network path with the first intervening device, and generate, according to a routing constraint of the network, the network path based on the first intervening device and a preference level of each of the first plurality of candidate devices. The instructions further includes a look-ahead analyzer configured to generate the preference level of each corresponding candidate device of the first plurality of candidate devices, the preference level representing a probability of including a candidate device in the network path.
