Abstract
Some embodiments provide a method for a hardware forwarding element deparser. The method receives, from a match-action pipeline, (i) packet header field values stored in a set of data containers and (ii) a set of data indicating which packet header fields, of multiple possible packet header fields, to include in a packet constructed from the packet header field values. The method uses the received set of data and a list of data container identifiers for multiple possible packet header fields to generate an ordered list of references to data containers of the set of data containers. Based on the ordered list, the method constructs the packet using the packet header field values stored in the referenced data containers.
