Abstract
A key is descriptive of a data packet, and a fingerprint hash function is applied to such a key to generate a fixed length fingerprint of the key. An index value is determined based on a portion of the fingerprint. A hash table could be populated by storing in a memory, at a memory location associated with the index value: a remainder of the fingerprint other than the portion of the fingerprint that was used to determine the index value, to indicate that data packets consistent with the key are to be handled in accordance with packet handling metadata. During packet processing, if a memory location associated with an index value stores a remainder of the fingerprint other than the portion of the fingerprint that was used to determine the index value, a data packet is handled according to packet handling metadata associated with the fingerprint.
