In one embodiment, a device in a network maintains a topology database of one or more topologies of entities in the network. The device identifies a replacement entity that has physically replaced a particular one of the entities in the network. The device determines whether neighbor information regarding one or more of the entities that neighbor the replacement entity matches neighbor information in the topology database associated with the replaced entity. The device determines whether client information regarding one of more clients of the replacement entity matches client information in the topology database associated with the replaced entity. The device sends an alert when the neighbor or client information of the replacement entity does not match the neighbor or client information in the topology database associated with the replaced entity.

Automated network entity replacement based on historical topology consciousness

A technique for synchronizing data caches. Data is maintained in the data caches as records. The records are associated with buckets which represent collections of one or more records. The buckets are collectively maintained in a synchronization set which represents a state of a data cache. A local entity synchronizes its data cache with a remote entity by sending its synchronization set to the remote entity in a synchronization request message. The remote entity compares information contained in the local entity's synchronization set with its own to determine if the two are consistent. If not, the remote entity notes inconsistencies in a response message that is then forwarded to the local entity. The local entity processes the response message including using it to update its data cache to be consistent with the remote entity's data cache.

A method and apparatus for generating configuration files using policy descriptions is provided. The present invention provides a method of generating a binary configuration file by receiving an identification encoded filename, parsing the identification encoded filename to determine identification parameters, matching the identification parameters to a set of configuration policy data to create configuration file parameters, and generating the binary configuration file from the configuration file parameters. The identification encoded filename can be can be run through an authentication check to provide increased security. Once created, the binary configuration file can also be validated, providing increased integrity. In one aspect of the present invention implemented is provided on a TFTP server. In another aspect of the invention an LDAP server is queried for certain configuration policy data, the configuration policy data being optionally cached on the TFTP server. The resulting configuration can be generated according to the DOCSIS configuration file standard, including removing non-version applicable DOCSIS configuration file parameters. The present invention can also be used to generate an annotated configuration file from the configuration file parameters, the annotated configuration file being viewable through a user interface.
