Summary:Embodiments of the apparatus for extracting data from packets relate to programmable layer commands that allow fields from packets to be extracted. A packet is split into individual layers. Each layer is given a unique layer type number that identifies the layer. Based on the layer type, each layer is expanded to a generic format. Each layer has a set of layer commands that is generic to that layer. Fields of each layer command are fieldOffset and fieldLen. These layer commands allow information in the packet to be extracted in a programmable manner. Extracted fields from each protocol layer are concatenated to form a token layer. All token layers are concatenated to form a final token, which is used for further processing of the packet.
