Abstract
A buffer () for temporarily storing a packet is installed in a packet order control circuit (H). A comparison circuit () compares the packet ID of an input packet with a next-selection ID indicating the packet ID of a packet to be selected next in accordance with an order. If the comparison result indicates that the packet ID and the next-selection ID do not match, a control circuit () stores the input packet in a storage position corresponding to the packet ID. If the packet ID and the next-selection ID match, the control circuit () selects the input packet as a target of a transfer process without storing the packet in the buffer (). If the next-selection ID matches the packet ID of a packet stored in the buffer (), the control circuit () selects the packet as a target of the transfer process. This guarantees the packet processing order with few memory resources.
