摘要: A system and method for updating packet headers using hardware that maintains the high performance of network element. In one embodiment, includes an input port process (IPP) (310) buffers received forwards header information to search engine. The engine searches a database maintained on switch element determine type packet. sends IPP along with destination address (DA) be updated if is routed, or VLAN tag has been identified forwarded particular VLAN. An output (OPP) (330) selectively performs additional modifications modified issue control signals interface (i.e., MAC). MAC (335) replaces source field generates CRC appended end
