Title
(EN) Filtering of packets for packet types at network devices
Abstract
(EN)

Examples include a network device to filter a packet for a packet type. The network device includes a filter to receive the packet and to determine whether the packet is a defined packet type. The network device also includes a Bloom filter to receive the packet from the filter based on the determination that the packet is a defined packet type and to determine whether the packet is a matched packet or an unmatched packet. A processing resource of the network device may receive the packet from the Bloom filter based on the determination that the packet is a matched packet and to determine whether the packet is an exact match.
