Patent

CA 2434245

Upon receiving a transmission request (REQ1) of a client device (1), a server device (11) transmits a group address (INF1) to the client device (1). The server device (11) designates the group address (INF1) and transmits the first block (X1) of blocks (X1 to X4) into which the requested information is divided to a network (10). Upon receiving a transmission request (REQ2) of a client device (2) after the transmission of the block (X1) to the client device (1), the server device (11) transmits a group address (INF2) to the client device (2). The server device (11) designates group addresses (INF1 and INF2) and transmits the second to fourth blocks (X2 to X4) to the network (10). The server device (11) designates the group address (INF2) and transmits the first block (X1) to the network (10) subsequently after the transmission of the fourth block (X4), thus ending the transmission.

L'invention concerne un procédé selon lequel, à réception d'une demande de transmission (REQ1) émise par un dispositif client (1), un serveur (11) transmet une adresse de groupe (INF1) au dispositif client. Le serveur (11) désigne l'adresse de groupe (INF1) et transmet le premier bloc (X1) des blocs (X1 à X4), dans lequel les informations demandées sont divisées, à un réseau (10). A réception d'une demande de transmission (REQ2) émise par un dispositif client (2) après la transmission du bloc (X1) au dispositif client (1), le serveur (11) transmet une adresse de groupe (INF2) au dispositif client (2). Le serveur (11) désigne les adresses de groupes (INF1 et INF2) et il transmet les blocs (X2 à X4) au réseau (10). Le serveur (11) désigne l'adresse de groupe (INF2) et il transmet le premier bloc (X1) au réseau (10) juste après la transmission du quatrième bloc (X4), achevant ainsi la transmission.
