Abstract: Programmatically defined fields of metadata for a network packet may be generated. Instructions indicating different portions of data from different headers of a network packet may be stored at a packet processor. When a network packet is received, the different portions of the data may be extracted from the different headers of the packet according to the instructions and provided to other stages of the packet processor for processing. Different portions of the same programmatically defined field may be utilized at different stages in the packet processor. The programmatically defined field may be used to generate a hash value that selects an entry in a lookup table describing a forwarding decision for a network packet.
