Abstract
A device and a method for processing a data packet. The method includes: receiving a key, applying multiple hash functions to provide multiple hashed values; accessing a group of hash tables using the multiple hashed values; associating between the key and an accessed vacant entry of an hash table out of the group of has tables. The device includes a communication controller connected to at least one memory bank; wherein the communication controller is adapted to receive a key associated with a data packet, apply multiple hash functions to provide multiple hashed values; access a group of hash tables stored within the at least one memory bank, using the multiple hashed values; and determine a data packet processing operation in response to a content of accessed entries of the multiple hash tables.
