APPARATUS AND METHOD FOR PROCESSING ETHERNET HEADER

摘要

An apparatus and a method for processing an Ethernet header are provided to implement an Ethernet processing function in a network communication device requiring a high speed process and to offer an Ethernet frame processing function to a router not having an Ethernet interface. An apparatus for processing an Ethernet header includes an input interface device receiving an Ethernet frame inputted from a medium access control framer. An Ethernet header analyzing device(230) analyzes the frame kind of the Ethernet frame received from the input interface device and extracts a destination and a source address. A filtering device(240) filters the destination and the source address extracted by the Ethernet header analyzing device. A frame check sequence checking device(250) checks the Ethernet frame filtered by the filtering device for data integrity. An Ethernet header removing device(260) removes the Ethernet header when a check result of the frame check sequence checking device is a normal state. An output interface device outputs a frame where the header is removed by the Ethernet header removing device to an upper processor.
