A scaleable high-capacity network comprises several non-uniform composite-star networks interconnected by a number of lateral uniform composite-star networks, thus forming an irregular two-dimensional network. Each non-uniform composite star network comprises electronic edge nodes, possibly of significantly different capacities, interconnected by optical core nodes. The optical core nodes are not connected to each other, and each may be configured differently and have a different reach index, where the reach index of a core node is the number of edge nodes to which the core node directly connects. The selection of a route through a core node within a non-uniform composite-star network is based on a composite index determined according to the reach index of the core node and the propagation delay along the route. The selection of a route in the irregular two-dimensional is based on pre-computed trail sets where each trail is a cascade of trail segments and each trail segment comprises at least one track connecting two edge nodes through a core node.
