File unit management method of system configuration information for efficient maintenance of network equipment

摘要

The present invention relates to a method for managing file-level configuration information in a variety of complex network equipment and an effective configuration data system, and processes the configuration data of the system in file units and records them in a specific device (flash card) used by the system. And the ability to preserve. This not only improves the reliability of the system, but also enables the efficient operation of the system by frequently recording, preserving and restoring system configuration data during operation. A preferred embodiment of the file unit management method of the system configuration information for efficient maintenance of the network equipment according to the present invention, the network management system, Ethernet, the main processor module, switching module, subscriber module module in a network system consisting of various modules In order to manage and control various software and various configuration information, the main processor module includes a flash card which is a nonvolatile memory, and the subscriber interface module uses a RAM disk that uses a volatile memory (D-RAM).;According to another preferred embodiment of the present invention, in order to efficiently maintain the software image and configuration information used in the system through the change and control (read and write) of the file unit, the operator may configure the configuration information of the network system. Changing process; Recording the changed configuration information in a corresponding configuration file in a storage device for a network management system; Giving a configuration information change command using a simple network management protocol (SNMP); Requesting a configuration information file using a file transfer protocol (TFTP) to a network management system by operating a configuration management function among software functions of a main processor board having a communication channel with the network management system; Downloading the requested configuration information file; As soon as the file is downloaded, the file is written to the flash disk of the main processor and the existing file is saved as a backup file for later recovery; After the necessary configuration information is changed, performing a corresponding function by a configuration management function to newly configure necessary resources (hardware chip or software environment variables); If the recorded file is the configuration information used in a particular subscriber interface module, the configuration management function in the main processor module is immediately notified to the subconfiguration management function in the corresponding subscriber interface module with the new configuration information. Downloading the necessary software images and configuration information using the internal communication channel device in the switch; When the software starts to operate, the configuration management sub-function in each subscriber interface module operates, requesting the configuration information file required for the module using the file transfer protocol in the same way, downloading the file, and then downloading the file to the required device (hardware). Configuring the port, chip, call information, etc.) and delivering the contents to required software modules; And writing to the RAM disk.
