Abstract

A multi-level content addressable memory (CAM) architecture compresses out much of the redundancy encountered in the search space of a single CAM, particularly for flow-based lookups in a network. Destination and source address may be associated with internal equivalence classes independently in one level of the multi-level CAM architecture, while flow-specific properties linking arbitrary classes of the destination and source addresses may be applied in a later level of the multi-level CAM.
