Abstract: front page image
(EN)When a communication device with a communication protocol including at least two layers receives data from another communication device, a processing load is reduced, which occurs when performing a reception order control on data received by an upper-level layer through a lower-level layer. The lower-level layer in the communication device with the communication protocol including at least two layers comprises a data reception unit for receiving data including a sequence number transmitted from another communication device, a buffer for storing the received data, a data transmission unit for replying whether the data has been received successfully or not, a buffer control unit for, when unsuccessfully received data is retransmitted from another communication device and the retransmitted data is received successfully, sorting the storage order of the data in the buffer so that the storage order of the retransmitted data corresponds to the order of the sequence number, and a data transfer unit for transferring the data stored in the buffer to the upper-level layer.
(FR)
(JA) 少なくとも2つのレイヤを含む通信プロトコルを備えた通信装置が他の通信装置からデータを受信する際に、上位のレイヤが下位のレイヤを介して受信したデータの受信順番制御を行う際の処理負荷を低減する。少なくとも2つのレイヤを含む通信プロトコルを備えた通信装置における下位のレイヤは、他の通信装置から送信されたシーケンス番号を含むデータを受信するデータ受信部と、受信したデータを記憶するバッファと、データの受信に成功したか否かを返信するデータ送信部と、受信に失敗したデータが他の通信装置により再送され、該再送された再送データの受信に成功した場合に、再送データの記憶順番がシーケンス番号の順番となるように、バッファにおけるデータの記憶順番を並べ替えるバッファ制御部と、バッファに記憶したデータを上位のレイヤへ転送するデータ転送部とを有する。
