Abstract
Packet processing is broken into two or more stages. In particular, the network processing unitperforms a first stage of packet processing related to packet forwarding and packet modification, and then performs a second stage of packet processing unrelated to packet forwarding and packet modification. Example processes unrelated to packet forwarding and packet modification may include state updates on the network element, such as statistics counter updates, stateful flow tracking, IPFix processing, MAC learning, and other processes important to operation of the network element, but which do not affect the appearance of the packet (e.g. packet format) and which do not affect the forwarding decision of the packet. Once the first stage of packet processing related to packet forwarding and packet modification has been completed, the flag associated with the packet is cleared in the scoreboard, to allow the packet to be transmitted from the reorder queue.
