Network router having an internal automated backup
First Claim
1. A network router having an internal automated backup, comprising:
- a primary port facility;
a card array having at least one unutilized backup router card; and
a switched fabric, wherein the switched fabric automatically replaces a failed router card connected to the primary port facility with an unutilized backup router card from the card arrays, wherein the switched fabric comprises an information system for receiving a failure message from the primary port facility, and a switching system for physically replacing the failed router card with the backup router card in response to the failure message, wherein the switching system includes a replacement mechanism for physically replacing the failed router card with the backup router card, wherein the replacement mechanism physically disconnects the failed router card from the primary port facility, physically moves the failed router card to an expanded bay, physically disconnects the unutilized backup router card from the card array, physically moves the unutilized backup router card from the card array to the primary port facility from which the failed router card was moved, and physically connects the unutilized backup router card to the primary port facility from which the failed router card was moved.

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.

6. A network router having an internal automated backup, comprising:
-
a primary port facility; a card array having at least one unutilized backup router card; and a switched fabric for automatically replacing a failed router card connected to the primary port facility with an unutiized backup router card from the card array, wherein the switched fabric includes an information system for receiving a failure message from the primary port facility and a switching system for replacing the failed router card with the unutiized backup router card, wherein the switching system includes a replacement mechanism for physically replacing the failed router card with the backup router card, wherein the replacement mechanism physically disconnects the failed router card from the primary port facility, physically moves the failed router card to an expanded bay, physically disconnects the unutilized backup router card from the card array, physically moves the unutilized backup router card from the card array to the primary port facility from which the failed router card was moved, and physically connects the unutilized backup router card to the primary port facility from which the failed router card was moved. - View Dependent Claims (7, 8, 9, 10, 11)

12. A network router having an internal automated backup, comprising:
-
a primary port facility having a primary processor and a secondary processor; a card array having unutilized backup router cards; and a switched fabric for automatically replacing a failed router card connected to the primary port facility with an unutilized backup router card from the card array, wherein the switched fabric includes an information system for receiving a failure message from the primary port facility and a switching system for physically replacing the failed router card with the unutilized backup router card, wherein the switching system comprises a replacement mechanism that physically connects and disconnects router cards from the primary port facility and the card array, wherein the replacement mechanism physically disconnects the failed router card from the primary port facility, physically moves the failed router card to an expanded bay, physically disconnects the unutilized backup router card from the card array, physically moves the unutilized backup router card from the card array to the primary port facility from which the failed router card was moved, and physically connects the unutilized backup router card to the primary port facility from which the failed router card was moved. - View Dependent Claims (13, 14, 15)
