    Abstract: Methods and apparatus are disclosed for performing lookup operations using associative memories, including, but not limited to modifying search keys within an associative memory based on modification mappings, forcing a no-hit condition in response to a highest-priority matching entry including a force no-hit indication, selecting among various sets or banks of associative memory entries in determining a lookup result, and detecting and propagating error conditions. In one implementation, each block retrieves a modification mapping from a local memory and modifies a received search key based on the mapping and received modification data. In one implementation, each of the associative memory entries includes a field for indicating that a successful match on the entry should or should not force a no-hit result. In one implementation, an indication of which associative memory blocks or sets of entries to use in a particular lookup operation is retrieved from a memory.

    Abstract: Fields of entries are mapped into new values with these mapped values combined into mapped entries for use in lookup operations typically for packet processing. One implementation identifies a list including multiple items each having a first field and a second field. The unique first and second fields of each item are respectively mapped to mapped first and second fields. A first associative memory is programmed with the unique first fields, and a first stage memory is programmed with the mapped first fields at corresponding locations. A second associative memory is programmed with the unique second fields, a second stage memory is programmed with the mapped second fields at corresponding locations. A second stage associative memory is then programmed, using the mapped first and second fields, with entries corresponding to one or more of the original multiple items.

    Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, and mechanisms, for policy-based processing of packets, including mechanisms for managing the policies. A user is authenticated and its user group identifier is identified. A packet is received and is associated with the user group identifier, and one or more fields (typically other than the source address field) of the packet are used to identify a second group identifier. A lookup operation is then performed on a policy based on the first and second group identifiers to identify a packet processing action to be performed on the packet. These identifiers are typically not network addresses, which disassociates the policy from physical network addresses (which often are dynamically assigned and may also vary based on the access point into the network of a user), and allows a switching device to process packets based on a policy stated using group identifiers.
