Abstract
A method and apparatus for use with a computer system are disclosed. A packet is received that includes a header. The header indicates at least one characteristic that is associated with a layer of a protocol stack. The packet is parsed in hardware to extract the characteristic(s), and the packet is processed based on the parsing. Hardware may construct subsequent headers and update fields of the transport, network and data link layers.
