The disclosed embodiments relate to a system that provides an intelligent port infrastructure for communication network devices. This is accomplished by incorporating a highly configurable pre-classifier module into the port infrastructure. This pre-classifier makes it possible to realign packet data to add a configurable number of bytes to the front of the packet, and also to select interesting data from incoming packets for further analysis. The selected data is sent into a configurable classification engine, which generates instructions that specify how to determine associated packet attributes. The packet attributes are then generated based on the instructions, and are forwarded along with the packet to downstream processing units.

Method and apparatus for pre-classifying packets

Apparatus () for processing pipelined data, comprises a storage unit and at least one logic unit () for executing operations on a block () of data. The storage means comprises an instruction table () comprising at least one instruction, and the at least one logic unit () is in at least one pipelined processing stage adapted to receive the block () and a first instruction () of the at least one instruction and execute the first instruction (). The invention also relates to a method for processing pipelined data, a module () for processing pipelined data, an integrated circuit (), a circuit board assembly (), a computer unit () and a pipelined processing system.
