Abstract
The invention relates to a method and device for configurable parsing of packet headers in a network. A configurable packet header parser (CPHP) includes hard-coded packet header logic implementing a hard-coded state machine and a reconfigurable header parsing logic that is coupled to the hardcoded logic and includes programmable registers. The CPHP is remotely programmable by means of a command packet parser that may receive command packets carrying CPHP configuration data and program the registers with the CPHP data to enable parsing packet including new types of headers. The hybrid hard-coded/programmable CPHP requires only a relatively small number of programmable elements enabling ASIC-based implementation.
