ABSTRACT:
One embodiment of the present invention provides a system that communicates a data packet in a network to a target node. In doing so, the system receives a node identifier for the target node, and determines a first positional label, based in part on the node identifier, for reaching a first anchor node from a root node in the network. The first anchor node stores a second positional label for reaching the target node from the root node in the network, which comprises a number of nodes coupled to the root node in a tree topology. The system then retrieves the second positional label from the first anchor node, and communicates the data packet to the target node based in part on the second positional label.
