輻輳時には受信したフレームの内、エフレームを
選択的に廃棄し制御フレームを優先的に処理する
ことにより相手応答未確認によるリンク切断が発
生する頻度を小さくすることを特徴とするバツフ
ア制御方式。 In the line control unit of the communication control device, when there is reception processing congestion, E-frames are selectively discarded among the received frames and control frames are processed preferentially, thereby reducing the frequency of link disconnections due to unconfirmed response from the other party. The buffer control method is characterized by:
