  • Network router having an internal automated backup
    Patent number: 7028224
    Abstract: A network router having an internal automated backup is provided. Specifically, the present invention provides a network router having at least one primary port facility, a switched fabric, and a backup card array. When a router card connected to a primary port facility fails, a failure message is automatically sent to the switched fabric. The switched fabric then disconnects the failed card from the primary port facility and places it in an extended bay. Thereafter, the switched fabric connects a backup router card from the backup card array to the primary port facility. In addition, the primary port facilities under the present invention can include a primary and a secondary processor for more reliable communication.
