    a network state decision section for deciding whether the network is in a spike state according to the received data packets; and

    a buffer adjusting section, which predicts the sequent data packets in one group of data packet when the network is decided to be in a normal state to adjust the size of buffer, and predicts the sequent data packets in one data packet when the network is decided to be in a spike state to enlarge the buffer.
