Abstract
In a network device, a hash-based lookup system includes a hash generator configured to apply respective hash functions to a lookup key to generate respective hash values. Each hash function corresponds to a respective logical hash bank in a hash table. A number of hash values generated by the hash generator corresponds to the number of logical hash banks in the hash table, and the number of hash values generated by the hash generator is configurable. The hash-based lookup system also includes an address generator that is configured to generate respective addresses to a memory that stores the hash table, the respective addresses within respective address spaces of respective logical hash banks of the hash table. The address generator uses i) a parameter N that specifies the number of logical hash banks in the hash table, and ii) N hash values generated by the hash generator, to generate the respective addresses.
