Abstract
A value is hashed and then a lookup operation is performed in a content addressable memory based on the hashed value to generate a content addressable memory result, which is used in performing an operation. In one implementation, the content addressable memory result includes an address, and the operation performed includes retrieving a record from memory, comparing a key value stored in the record to the first value to identify the correct record, and then updating a statistics value in the record. In one embodiment, an original value is masked to generate the value which is hashed. In one implementation, the value corresponds to a masked or original flow identification value associated with a flow of packets.
