Global network management configuration
View Patent ↗A method and system are disclosed for remotely storing information for initializing a configurable network device at a direct server in the network. The information for initializing the configurable network device is automatically retrieved and used by the network device to self-initialize after the network address of the directory server is provided. Included in the information in some embodiments are the network addresses of a policy server and an authentication server, thereby allowing the network device to automatically retrieve policy information and authentication information as needed. Remote storage of substantially all information used to setup and run the network device substantially reduces the effort needed to backup or change information for large distributed networks including numerous configurable network devices.

determining that a shared resource server (SRS) having shared resource information (SRI) stored thereon is accessible by the CND, wherein said SRI is accessible from the SRS by the DSSI server dependent upon a SRS identifier included in the DSSI;
retrieving the SRI for the CND from the SRS thereby causing a local copy of the SRI and the DSSI to be retained at the CND;
repeating the DSSI retrieving step one or more times while the CND is in a standard operational state in response to determining that the SRS is not accessible by the CND;
caching the DSSI acquired in the retrieving step in a CND memory; and
determining whether or not the SRS is accessible includes determining if the DSSI includes an identifier corresponding to the SRS; and
after the step of retrieving the associated DSSI, determining whether the current DSSI server identifier retrieved from the DSSI server is different than a previous DSSI server identifier retained in CND memory and retrieving DSSI from the DSSI server using the current DSSI server identifier retrieved if different than the previous DSSI server identifier.

11. The automated setup method in claim 1 , wherein the DSSI server is a directory server.
12. The automated setup method in claim 1 , wherein the method further comprises, after the step of retrieving the associated DSSI, the steps of:
determining whether the current policy server identifier retrieved from the DSSI server is different than a previous policy server identifier retained in CND memory; and
retrieving policy information from the policy server using the current policy server identifier if different than the previous policy server identifier.
13. The automated setup method in claim 1 , wherein the method further comprises, after the step of retrieving the associated DSSI, the steps of:
determining whether the current authentication server identifier retrieved from the DSSI server is different than a previous authentication server identifier retained in CND memory; and
retrieving authentication information from the authentication server using the current authentication server identifier if different than the previous authentication server identifier.
14. The automated setup method in claim 1 , wherein the DSSI server and the policy server are the directory server.
15. The automated setup method in claim 1 , wherein the DSSI server and the policy server are different servers.
16.
