Abstract
A router has a shape graph that is a compressed form of a trie that represents routing information for routing data packets in a network, and an update data structure that includes plural entries corresponding to nodes of the shape graph, the plural entries containing count values indicating respective numbers of nodes of the tie represented by the corresponding nodes of the shape graph. The router incrementally updates the shape graph as a portion of the routing information changes, where the incremental updating uses information in the update data structure.
