Abstract: A partial packet context builder can determine a partial packet context associated with a data packet based upon packet context associated with the data packet, the partial packet context including a plurality of partial packet context fields, where a network packet processor including an action unit, the action unit including the partial packet context builder, a systolic array of arithmetic-logical units (ALUs), and a packet context builder, the packet context including a plurality of packet context fields. The systolic array of ALUs can process the partial packet context to provide a processed partial packet context, the processed partial packet context including a plurality of processed partial packet context fields. The packet context builder can merge the processed partial packet context with the packet context to provide a processed packet context.

Abstract: A switch controller, where the switch controller includes a processor that is configured to: receive a multicast packet from a sender, where the multicast packet includes a header and a payload, determine that an attempt to forward the multicast packet through one or more ports fails for at least one of the one or more ports, determine that a header-forwarding bit in the header is set, and send the header of the multicast packet to the sender.
