Abstract: A network interface device with resource reservation protocol-traffic engineering capability and improved hot redundancy. A first interface card is provided for receiving a request, which specifies a data session between two host devices in a network, from an adjacent node in the network, and for storing a session parameter based on the request. A standby interface card is provided for receiving a request from the active interface card, based on the request received by the active interface card, and for storing another session parameter, concurrently with a storing of the session parameter by the active interface card, based on the request. Failure detection circuitry is provided for detecting a failure within the active interface card, and for coupling the second interface card to the adjacent node depending on whether or not a failure is detected.
