Abstract
A packet switching node in a pipelined architecture processing packets received via an input port associated with the packet switching node performs a method, which includes: determining a packet frame type; selectively extracting packet header field values specific to a packet frame type, including packet addressing information; ascribing to the packet a preliminary action to be performed; searching packet switching information tracked by the packet switching node based on extracted packet addressing information; formulating a preliminary switch response for the packet; classifying the packet into a packet flow; modifying the preliminary switch response in accordance with one of the preliminary action, the packet flow into which the packet was classified, and a default port action corresponding to the input port; modifying the packet header in accordance with one of the preliminary action, the packet flow, and the default port action; and processing the packet.
