(EN) RECEIVING DEVICE AND TRANSMITTING DEVICE FOR TCP COMMUNICATION
(FR) DISPOSITIF DE RÉCEPTION ET DISPOSITIF DE TRANSMISSION POUR UNE COMMUNICATION TCP
Abstract
(EN) The present invention generally relates to Transmission Control Protocol (TCP) and TCP Offload engine (TOE). In particular, the invention proposes a receiving device and a transmitting device for TCP communications. The transmitting device is configured to insert an identifier into a TCP segment that it sends to the receiving device. The receiving device is configured to obtain this identifier from the TCP segment. The identifier includes information that enables the receiving device to directly access a connection context at the receiving device, wherein the connection context relates to a connection between the transmitting device and the receiving device. The present invention also relates to corresponding methods, and particularly a method for automatic management and configuration of the identifier between the transmitting device and the receiving device by exchanging control information.
(FR) La présente invention concerne d'une manière générale un protocole de commande de transmission (TCP) et un moteur de délestage TCP (TOE). En particulier, l'invention concerne un dispositif de réception et un dispositif de transmission pour des communications TCP. Le dispositif de transmission est configuré pour insérer un identifiant dans un segment TCP qu'il envoie au dispositif de réception. Le dispositif de réception est configuré pour obtenir cet identifiant provenant du segment TCP. L'identifiant comprend des informations qui permettent au dispositif de réception d'accéder directement à un contexte de connexion au niveau du dispositif de réception, le contexte de connexion se rapportant à une connexion entre le dispositif de transmission et le dispositif de réception. La présente invention concerne également des procédés correspondants, et en particulier un procédé de gestion et de configuration automatiques de l'identifiant entre le dispositif de transmission et le dispositif de réception par échange d'informations de commande.
