Abstract: A packet processing apparatus and method are provided. The packet processing apparatus changes a size of an input packet, analyzes the input packet to perform a second layer associated process, generates basic delivery headers of the input packet, processes the input packet to which the basic delivery headers are inserted according to a type of the input packet, transforms the header of the input packet to which the basic delivery headers are inserted, and transitions the header-transformed input packet to delivers the packet. Accordingly, it is possible to process various packets without addition of separate process to the packet processing apparatus. In addition, a use efficiency of a network processing unit can be optimized, so that it is possible to increase a packet processing rate and performance.

Abstract: An SPI bridge, a packet processing apparatus and a method thereof are provided to maximize the efficiency in the use of a network processor by processing packets through one line card. A mode selector(312) selects the packet mode of a received packet, and then removes a preamble of the packet correspondingly to the selected packet mode. A frame analyzer(313) extracts a destination address through the packet analysis. An LU controller(314) checks whether the packet is forwarded to an uplink through the search of the extracted destination address. An FCS chop controller(315) removes the FCS of the packet or filters the packet.

Abstract: PURPOSE: A backbone edge switching apparatus and a method for processing a packet are provided to compensate a transmission service by a data link layer and a network layer. CONSTITUTION: An L2 lookup unit(131) performs lookup about a specific layer information of a packet. The L2 look-up unit creates a first flow of the packet. If the additional lookup is requested, an L3 lookup unit(132) performs an additional lookup about the different layer information of the packet. The L3 lookup unit creates the second flow of the packet. An integration service management unit(133) mixes the second flow which is generated by the L3 lookup unit with the first flow. The integration service management unit determines the mixed flow as a packet transmission flow.
