(FR) DISPOSITIF DE TRANSFERT, PROCÉDÉ DE TRANSFERT ET PROGRAMME
(JA) 転送装置、転送方法及びプログラム
Abstract:
(EN) A transfer device according to one embodiment of this invention comprises: a receiving unit which receives packets from a source which distributes data in accordance with a TCP (Transmission Control Protocol); a storage unit which stores, in a buffer, data inside a received packet, on the basis of the TCP sequence number of the received packet; a TCP transfer unit which transfers the received packet to a first sink which requests distribution in accordance with TCP; and a UDP transfer unit which reads off the data from the buffer, and requests the distribution of the read-off data in accordance with a UDP (User Datagram Protocol).
(FR) L'invention concerne, selon un mode de réalisation, un dispositif de transfert comprenant : une unité de réception qui reçoit des paquets provenant d'une source qui distribue des données conformément à un protocole de commande de Transmission TCP (TCP)) ; une unité de stockage qui stocke, dans un tampon, des données à l'intérieur d'un paquet reçu, sur la base du numéro de séquence TCP du paquet reçu ; une unité de transfert TCP qui transfère le paquet reçu à un premier récepteur qui demande la distribution conformément au TCP ; et une unité de transfert UDP qui lit les données à partir du tampon, et demande la distribution des données de lecture conformément à un protocole UDP (protocole de datagramme utilisateur).
(JA) 本発明の一形態に係る転送装置は、TCP(Transmission Control Protocol)に従ってデータを配信するソースからパケットを受信する受信部と、前記受信したパケットのTCPシーケンス番号に基づき、前記受信したパケット内のデータをバッファに格納する格納部と、前記受信したパケットをTCPに従った配信を要求する第1のシンクに転送するTCP転送部と、前記バッファから前記データを読み出し、当該読み出したデータをUDP(User Datagram Protocol)に従った配信を要求する第2のシンクに転送するUDP転送部とを有する。
