摘要： 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.

摘要： A data center topology routes traffic between internal sub-nets and between a sub-net and an outside network through a common chain of services. The data center topology employs transparent layer 7 and layer 4 services on a common chassis or platform to provide routing, load balancing and firewall services while reducing the number of devices necessary to implement the data center and simplifying configuration.

摘要： Methods, apparatus, and other mechanisms are disclosed for merging lookup results, such as from one or more associative memory banks and/or memory devices. In one exemplary implementation, multiple associative memories or associative memory banks are configured to substantially simultaneously generate a plurality of lookup results based on a lookup value. Multiple memories are each configured to generate a corresponding result based on the lookup result generated by its corresponding associative memory or associative memory bank. A combiner is configured to receive and merge these corresponding results generated substantially simultaneously in order to identify the merged lookup result.

摘要： 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.
