Abstract
Embodiments provide a method, including: receiving, by a forwarding element, a packet through an inbound port; searching for, by the forwarding element, a port table according to the inbound port and determining a first offset, a first length, and an identifier of a first table; determining, by the forwarding element, a first key according to the first offset and the first length, searching for the first table according to the first key, and determining a first instruction; and processing, by the forwarding element, the packet according to the first instruction. In addition, a forwarding element is provided. In the foregoing technical solutions, before processing a packet, the forwarding element does not need to interpret a data format of the packet, so that the forwarding element can flexibly support packets in different data formats.
