An apparatus and method for forwarding data on a network are described. A label-switching subnetwork within the network includes an ingress node and an egress node coupled to source and destination nodes, respectively, on the network. The ingress node sends a signal along a route within the subnetwork through a plurality of subnetwork nodes to the egress node. In response, the subnetwork nodes transmit response signals back along the route toward the ingress node which define the route through the subnetwork and simultaneously allocate a plurality of paths within the route. A single path can be selected for forwarding of data packets associated with a source/destination pair, ensuring that data packets arriving at the destination are not misaligned.
