Title (EN) ROUTER DEVICE USING FLOW DUPLICATION
(FR) DISPOSITIF DE ROUTEUR À DUPLICATION DE FLUX
Abstract:
(EN) A method and apparatus for routing a plurality of session packets across a network toward a destination modifies each packet to include a sequence number that is different from the sequence number of other packets in the plurality of packets. Accordingly, at this point, each of the plurality of packets is transformed into a corresponding plurality of processed packets. The method also duplicates the plurality of processed packets to produce a corresponding plurality of duplicated packets. Next, the method forwards the plurality of processed packets toward the destination using a first stateful path through the network, and correspondingly forwards the plurality of duplicated packets toward the destination using a second stateful path through the network. In preferred embodiments, the first stateful path is different from the second stateful path. For example, the two paths may be entirely distinct in that they share no common intermediary elements.
(FR) L'invention concerne un procédé et un appareil qui permettent d'acheminer une pluralité de paquets de session sur un réseau vers une destination, le procédé consistant à modifier chaque paquet pour inclure un numéro de séquence qui est différent du numéro de séquence d'autres paquets parmi la pluralité de paquets. Par conséquent, à ce stade, chacun de la pluralité des paquets est transformé en une pluralité correspondante de paquets traités. Le procédé duplique également la pluralité des paquets traités pour produire une pluralité correspondante de paquets dupliqués. Ensuite, le procédé transfère la pluralité des paquets traités vers la destination à l'aide d'un premier trajet à états par l'intermédiaire du réseau, et transfère de manière correspondante la pluralité des paquets dupliqués vers la destination à l'aide d'un second trajet à états par l'intermédiaire du réseau. Dans des modes de réalisation préférés, le premier trajet à états est différent du second trajet à états. Par exemple, les deux trajets peuvent être entièrement distincts en ce qu'ils ne partagent pas d'éléments intermédiaires communs.
