ABSTRACT:
In one embodiment, a method includes receiving a portion of a hash key vector. The hash key vector can be defined based on a range value and based on at least a portion of an address value from a data packet queued within a multi-stage switch. The method also includes defining, based on the hash key vector, a hash value associated with a location in a hash table when the portion of the hash key vector matches a bit vector stored in a tag table.
