A recursively partitioned static router-table, the data structure incorporating a first-level partition including subtries and an auxiliary trie. A node of the subtrie includes a path Q(N) from the root R of a trie T to a root N of the subtrie, a stride s for a next-level partition, a mask that characterizes a next-level perfect hash function, and a pointer to the hash table for the next-level partition. At least one of the trie T, the first-level partition, the auxiliary trie, and the next-level partition is represented by a base structure selected from the group consisting of MBT and HSST.
