Inventor: ANAND VISHAL
IPC: H04L49/111
Filed: 2015-06-19
Abstract: Embodiments of an apparatus for extracting data from packets relate to programmable layer commands which allow fields to be extracted from packets. A packet is split into individual layers. Each layer is given a unique layer type number which identifies the layer. Based on a layer type, each layer is expanded to a generic format. Each layer has a set of layer commands which are generic to the 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. Fields extracted 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.
