Claim One:
1. An information packet preclassification method comprising: receiving via an input interface port a packet of information; differentiating the packet into segments using a packet parsing engine (PPE); using a PPE decision tree random access memory (RAM) including a logic decision tree with multiple levels; comparing segments in the packet to a node at a tree level, wherein each node includes a plurality of node reference segments and corresponding node comparison operators, said comparing segments includes making a comparison between a first reference segment in the packet and node reference segments selected from a group consisting of a second reference segment in the packet and a predetermined segment value stored in memory; in response to comparing the segments to the nodes, the PPE assigning a plurality of classification attributes to the packet: packet; forwarding the packet to a processor for processing in response to a classification attribute; and using a user interface (UI) to select segments in the packet to be written.
