An integrated layer frame processing device for supporting Internet Protocol version 6 (Ipv6), in which the number of bytes to be processed is more than in Ipv4, and securing a bandwidth of at least several gigabits using an existing network processor is provided. The integrated layer frame processing device includes a variable header into which information is compressed and inserted and a hash key is generated in a data field that is recognized by a network processor so as to support a packet processing protocol for a system including a frame switch and a router. The integrated layer frame processing device is disposed between a physical layer and layer 2 processor and the network processor. Since the integrated layer frame processing device includes the variable header, a case where the number of bytes that are to be processed by the network processor is increased can be managed appropriately. Accordingly, the network processor can support Ipv6 and can map and manage layer 4 and layer 2 information as well as layer 3 information, i.e., Ipv4 in hardware.
