Examples relate to routing packets in dimensional order in multidimensional networks. A packet is received at a network device in a fully connected multidimensional network and all possible candidate output ports for the packet to be routed to the destination network device with a dimensional order are determined. The candidate output ports correspond to candidate minimal paths and candidate non-minimal paths between the network device and the destination network device. An optimal output port among all the candidate output ports is selected and the packet is routed to a next hop of the network though the optimal output port using a first resource class when the optimal output port corresponds to a candidate minimal path and a second resource class when the optimal output port corresponds to a candidate non-minimal path.
