| 20120195231 | DYNAMIC NAME GENERATION - A dynamic name of a device within a network may be generated by accessing information related to the device; accessing information related to a remote, neighbor device; generating a dynamic name of the device based on the accessed information related to the device and the accessed information related to the remote, neighbor device; and storing the generated dynamic name of the device. Alternatively, a topology map of devices within a network may be generated where a central controller may access, from memory, a dynamic name of controlled devices, the dynamic name of the controlled devices including information related to remote, neighbor devices of the controlled devices. The topology map may include dynamic names of the controlled devices. | 2012-08-02 |
