Method and apparatus for network management system
First Claim
1. A network management system having a system controller configured to connect to a bus having a plurality of ports, each of the ports having a port address, the system controller comprising:
- a memory configured to store the location of files associated with each of the port addresses, each of the files being of a file type;
a request receiver configured to receive a request for a file of a file type from an active router card connected to the system controller at one of the ports having a port address;
an identifier configured to use the memory, the port address and the request to identify the file, the request not containing a media access control (MAC) address for the active router card and not including information regarding a file name for the file to be retrieved; and
a sender configured to send the identified file to the active router card, the system controller being configured to simultaneously handle multiple image download requests, from multiple router cards, using multiple image download processes, wherein a non-active router card, which is designated as a backup to the active router card, runs a same image of the active router card when the non-active router card becomes active such that a failure of the active router card causes a reloading for the non-active router card and a new request for the same image, and wherein the new request causes the system controller to find the same image, along with configuration information, to be sent to the non-active router card.

Abstract
A network management system has a bus and a system controller connected to the bus. The bus has a plurality of fixed ports, where each of the ports is capable of connecting a router card to the system controller. A method of sending a file from the system controller to a router card includes receiving a request packet from the router card where the request packet includes a file type and the port address, identifying the file from the file type and the port address, and sending the file to the router card. The system controller has a memory storing the location of files associated with each of the port addresses, a request receiver for receiving a request for a file of a file type from a router card, an identifier for identifying a file, and a sender for sending the identified file to the router card. The router card has a memory for storing an operating system image and a configuration, and a request sender for sending a request for an operating system image and a configuration to the system controller upon power-up of the router card.

12. A network management system comprising:
-
an active router card configured to send a request for a file of a file type, wherein the request does not contain a media access control (MAC) address for the active router card, the request not including information of a file name of the file requested; and a system controller connected to the active router card at a port having a port address, the system controller configured to store the location of files associated with the port address in a memory, the system controller configured to access the memory and examine the request to retrieve the file, wherein the request is sent in response to the active router card being powered on such that its memory for storing configuration data and operating system data is substantially empty, wherein the system controller is configured to send the retrieved file to the active router card, the system controller being configured to simultaneously handle multiple image download requests, from multiple router cards, using multiple image download processes, wherein a non-active router card, which is designated as a backup to the active router card, runs a same image of the active router card when the non-active router card becomes active such that a failure of the active router card causes a reloading for the non-active router card and a new request for the same image, and wherein the new request causes the system controller to find the same image, along with configuration information, to be sent to the non-active router card. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A network system having a system controller configured to connect to a bus having a plurality of ports, each of the ports having a port address and being capable of connecting to an active router card, the system controller comprising:
-
means for receiving a request packet from the active router card, the request packet including a file type and the port address, the request packet not containing a media access control (MAC) address for the active router card and not including information regarding a file name for a file to be retrieved, wherein the request is sent in response to the active router card being powered on such that its memory for storing configuration data and operating system data is substantially empty; means for retrieving the file; means for transmitting a size and name of the file to the active router card; and means for sending one or more data packets comprising the file to the active router card, the system controller being configured to simultaneously handle multiple image download requests, from multiple router cards, using multiple image download processes, wherein a non-active router card, which is designated as a backup to the active router card, runs a same image of the active router card when the non-active router card becomes active such that a failure of the active router card causes a reloading for the non-active router card and a new request for the same image, and wherein the new request causes the system controller to find the same image, along with configuration information, to be sent to the non-active router card.
