Internet Protocol and Ethernet Lookup Via a Unified Hashed Trie

摘要

An apparatus comprising a ternary content-addressable memory (TCAM) configured to store a root node for each of a plurality of tries resulting in a plurality of root nodes, and at least one non-TCAM memory configured to store associated data that identifies each of the plurality of root nodes, and store a plurality of network address prefixes represented by one or more subtries which belong to a trie in the plurality of tries, wherein each subtrie is locatable at least partially based on the associated data for the root node.
