Abstract:
1. A method for checking a configuration of a plurality of configurable LRUs within a restricted architecture network having at least one configuration server in communication with the LRUs, the method comprising the following steps: operating each said respective LRU to generate a respective LRU configuration file in response to an initiation request received at each said respective LRU from a device other than the LRUs, the LRU configuration file containing a list that identifies software components currently residing on its respective LRU; operating each said LRU to transfer its respective LRU configuration file to the configuration server; operating the configuration server to detect the arrival of each said respective LRU configuration file; operating the configuration server to update a system configuration data file (SCDF) that contains data representing current and previous LRU configurations by setting the current SCDF data at the server to reflect the LRU configuration files generated by the generating step and by setting the previous SCDF data at the server to reflect LRU configuration files generated by the LRUs during a previous running of the configuration checking method; operating the configuration server, after performing the updating step, to determine whether any of the LRUs are to receive at least one updated software component from the configuration server and if so, identifying each of those LRUs as a target LRU; and operating each said target LRU to request information pertaining to said at least one updated software component from the configuration server.
