Abstract:
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.
