Abstract: A network device receives a fragmented packet of an internet protocol (IP) packet. The fragmented packet is subsequently received relative to an initial fragmented packet of the IP packet and includes a first set of tuple information. The network device determines an entry of a hash table associated with the IP packet, based on the first set of tuple information and a fragment identifier (ID) within the fragmented packet. The network device retrieves a second set of tuple information associated with the fragmented packet from the hash table entry, and transmits an indication of the first and second sets of tuple information.
