In addition to the manual backup process described above, a process for automatically backing up the in-device data of the transmission apparatus is performed regularly (eg, once a day, at a fixed time, etc.) by a predetermined number of units. It was. FIG. 10B shows an example of automatic backup processing of setting data in the apparatus by a scheduled operation. As shown in the figure, the automatic scheduled backup process

  As described above, the conventional backup processing method allows the transmission apparatus for which the setting operation has been performed to manually execute backup processing of data in the apparatus, or to each transmission apparatus at a predetermined time every day for a predetermined number. However, in the method of automatically performing backup processing at a predetermined time, the backup processing execution order is determined by managing each transmission device within the network operation system. For example, it is not always associated with the timing of transmission device setting data update, such as in the order of management numbers, so the backup processing of the transmission device setting data that has undergone an important setting operation such as line communication is not immediately performed. May be implemented after time has passed.

  In order to avoid this, it was possible to manually perform backup operations on necessary devices. However, the transmission device on which the operator performed an important setting operation was identified each time, and It is necessary to perform an operation for sequentially backing up setting data to a plurality of related transmission apparatuses.

  As a setting operation for a plurality of transmission devices, for example, when a path setting for line communication across a plurality of transmission devices is performed, the path of the path is grasped, and all transmission devices existing on the path are identified. Backup of the configuration data. In a network operation system that performs this manually, the operability is not efficient, and there is a concern that human error such as leakage of important setting data of the transmission device may occur. is there.

  In addition, the method of automatically executing the backup of the setting data of each transmission device for each predetermined number of times at the predetermined time described above can be applied to each transmission device even if there is no change in the setting data in the device. Thus, the backup of the same in-device setting data is performed, and unnecessary backup processing is performed wastefully, which is inefficient.

  The present invention automatically synchronizes the setting data in the apparatus only with respect to the transmission apparatus in which the setting data is changed in synchronization with the setting data update timing of the transmission apparatus, and the setting data backup is omitted In addition, it is possible to prevent inconsistency due to a time lag between actual setting data and backup data and human operation error, and to obtain accurate backup data efficiently. Further, it is possible to perform restoration processing in units of paths based on the accurate backup data.

  In order to solve the above problems, the network operation server device performs path setting means for setting path communication between the transmission devices, and timing immediately after the path setting is performed by the path setting means. Target device information extracting means for extracting device information of all transmission devices on the path of the path setting, which is a backup target of setting data related to path setting, and all transmission devices extracted by the target device information extracting means In addition, the apparatus includes backup processing means for performing backup of the in-device setting data at a timing immediately after the path setting is performed.

  Immediately after the backup of the in-device setting data performed for the transmission device, the backup data of the in-device setting data of each transmission device received as a response signal from the transmission device is transferred to the path related to the path setting. A backup data management table having a database structure stored as path setting information associated with the path name.

  Further, as the backup data management table, the current path setting table storing the current path setting information together with the registration date and time information and the current path list table are deleted from the current path list table. And an old path list table for storing path setting information to which information has been added.

  In addition, based on the context of the registration date / deletion date / time information of the path setting information stored in the old path list table and the specific specified date / time in the past, the path setting information at the specific specified date / time is stored in the old path list. Means for extracting from the table and registering it in the batch restoration data table, and causing each transmission device to restore the in-device setting data at a specific past date and time based on the path setting information registered in the batch restoration data table It is a thing.

  In addition, when registering the path setting information at the specified date and time in the past in the batch restoration data table, the registration date and time is specified among the path setting information of the same path name existing in the old path list table. Means for registering the path setting information closest to the designated date and time in the batch restoration data table.

  In addition, in the transmission device internal data management method, a path setting step for performing path setting for setting line communication between transmission devices from the network operation system, and a timing immediately after performing path setting in the path setting step. A target device information extraction step for extracting device information of all transmission devices on the path setting path, which is a backup target of the setting data related to the path setting, and all transmission devices extracted in the target device information extraction step On the other hand, it includes a backup processing step for backing up the setting data in the apparatus at a timing immediately after the path setting is performed.

  Immediately after the backup of the in-device setting data performed for the transmission device, the backup data of the in-device setting data of each transmission device received as a response signal from the transmission device is transferred to the path related to the path setting. The path setting information associated with the path name is stored in a backup data management table having a database structure.

  In addition, as the backup data management table, the current path setting information is stored in the current path list table together with the registration date and time information, deleted from the current path list table, and the deletion date and time are added to the path setting information in the current path list table. This includes a step of storing the path setting information with the added information in the old path list table.

  In addition, when a failure occurs in the current path setting route and switching to the backup path setting route is performed, the setting data of the path setting is immediately after the backup path setting is performed. A target device information extraction step for extracting device information of all transmission devices on the path setting path to be backed up, and for all transmission devices extracted in the target device information extraction step, This includes a backup processing step in which backup is performed at a timing immediately after the path setting is performed.

  In addition, when the transmission device constituting the communication network system is expanded or removed, and the path setting of the route passing through the added or removed transmission device is performed, at the timing immediately after performing the path setting, A target device information extraction step for extracting device information of all transmission devices on the path of the path setting, which is a backup target of setting data relating to the path setting, and all transmission devices extracted in the target device information extraction step On the other hand, it includes a backup processing step for backing up the in-device setting data at a timing immediately after the path setting is performed.

  When the disclosed network operation server device performs path setting, it automatically performs backup of the setting data in the device only for the transmission device related to the path setting, and acquires the backup data. Backup data synchronized with the device setting data update timing can be acquired, and accurate backup data can be prevented by preventing back-up of setting data, inconsistency due to time lag between actual setting data and backup data, and human error. Can be obtained. In addition, since the backup of the setting data in the apparatus is automatically executed only for the transmission apparatus in which the setting data has been changed, the backup process can be efficiently performed in a short time.

  Furthermore, it is possible to store accurate backup data synchronized with the timing of setting data update of the transmission device together with the registration date and time of deletion and restore the setting data of a specific specified date and time in the past to each transmission device using them. It becomes possible.

  FIG. 1 shows a configuration example of a network operation system (NE-OpS) for backup of setting data in a transmission apparatus. The network operation (NE-OpS) server device 1-10 includes a path setting process unit 1-1, an in-device setting data backup process unit 1-2, a path information storage unit 1-3, and an in-device data file storage unit 1. -4.

  Hereinafter, in the system configuration example in which six transmission apparatuses A, B, C, D, E, and F are targets for monitoring and control of the network operation system (NE-OpS), the transmission apparatus A is the starting point. An operation example of backup processing when path setting with the transmission apparatus D as an end point is performed will be described with reference to FIGS. 1 and 2.

  When the operator inputs a path setting request command for the transmission apparatus A → transmission apparatus B → transmission apparatus C → transmission apparatus D from the operation terminal (HMI) 9-1 to the network operation (NE-OpS) server apparatus 1-10. The path setting process unit 1-1 transmits path setting commands to the transmission apparatuses A, B, C, and D, respectively ((1) -1, (1) -2, (1)-in FIGS. 1 and 2). 3, (1) -4).

  Receiving the path setting command, each of the transmission apparatuses A, B, C, and D performs the designated path setting, and then transmits the execution result as a path setting completion response to the network operation (NE-OpS) server apparatus 1-10. To do. The network operation (NE-OpS) server apparatus 1-10 receives the path setting completion response from each of the transmission apparatuses A, B, C, and D, and then converts the apparatus information targeted for path setting into the in-device setting data. The backup process unit 1-2 is notified (2-1), and the in-device setting data backup process unit 1-2 responds to the notified path setting target device (that is, the transmission devices A, B, C, and D). Then, a backup request command for saving the setting data in each device and storing it in the storage unit in each device is transmitted ((2) -1, (2) -2, (2) -3 in FIGS. 1 and 2). (2) -4).

  The path setting target devices (transmission devices A, B, C, and D) each receive the backup request command, and then save the setting data in the own device as database information and perform backup ((3) in FIG. 2). -1, (3) -2, (3) -3, (3) -4). When the backup is performed, the path setting target device (transmission devices A, B, C, D) returns the backed up data to the network operation (NE-OpS) server device 1-10 as a backup completion response, and the network operation. The (NE-OpS) server device 1-10 takes backup data from each transmission device (2-3) and saves it.

  In this way, transmission on a path route that is a target of path setting is synchronized with the timing when a line communication path setting operation is performed between arbitrary transmission apparatuses from the network operation system (NE-OpS). The backup of the setting data in the apparatus is automatically performed for only the apparatus in sequence.

  The network operation (NE-OpS) server apparatus 1-10 manages the backup data in each transmission apparatus backed up each setting data every time the path setting is performed, and the backup data management of the in-apparatus data file storage unit 1-4. Save to table. The structure of the backup data management table of the in-device data file storage unit 1-4 is shown in FIG.

  The backup data management table manages the path name of the set path, the year / month / day / hour / minute / second (registration date / time) when the path was set, and the name of the backup data file in the device for each transmission device backed up when setting the path as one record information. Database structure. For the backup data file name in the device, a file name that does not overlap with the backup data file name in the device of another transmission device is assigned, such as [device name + year / month / day / hour / minute / second], and the file is displayed in the backup data management table. Register a name. The actual backup data in each device is managed under a fixed path directory.

  As the backup data management table, a current path list table shown in FIG. 3A and an old path list table shown in FIG. In the current path list table, the backup data file names in each device are registered for all paths that are actually set at the current time. In the old path list table, the backup data file names in each device of the deleted setting path are registered. sign up.

  The old path list table is for managing past path setting information that has been deleted. The old path list table is obtained by adding the deletion date and time of the set path to the structure of the current path list table. When the setting path is deleted in accordance with the operation change of the communication network system, the network operation (NE-OpS) server apparatus 1-10 deletes the record information of the setting path to be deleted from the current path list table ( “NULL” meaning “no” is written in the record), and the record information and the date and time of path deletion are written in the old path list table.

  In the example shown in FIG. 3, the path with the path name “AtoD PATH001” is deleted, the record with the path name in the current path list table is deleted, and the deletion date and time “2007/06/17 15:00” is added to the record information. "Is added to the old path list table. An example of writing as 58 records is shown.

  The old path list table shown in FIG. 3B shows an example having an area capable of managing backup data file names for up to 60 records. However, the maximum number of records (the number of management) can be changed according to the capacity of the storage device. The old path list table has a function of cyclically overwriting newest record information on the oldest record information. For this purpose, an old path list table counter indicating the record position of the oldest record information is provided.

  The record information of the path deleted from the current path list table is written at the record position indicated by the old path list table counter. When the writing is completed, the value of the old path list table counter is incremented by one. When the counted value exceeds the maximum number of management of the old path list table, the old path list table counter is reset to a value indicating the first record position of the old path list table. In this way, by providing the old path list table for managing past path setting information, the path setting state in the communication network at a specific past time can be restored (restored) by designating the time. It becomes possible.

  By providing such a backup data management table, it is possible to manage the in-device backup data files of all transmission apparatuses on the path of the setting path in association with the path name of the setting path. Further, since the set path information and the backup data file information in each transmission apparatus on the path of the set path are stored for all paths in the network operation (NE-OpS) server apparatus 1-10, any path unit It is possible to restore the in-device data of each transmission device at once, and restore the in-device data of each transmission device in batch units at any past time using the old path list table. Is possible.

  Next, with reference to FIG. 4, an operation example for collectively restoring the path setting state of the communication network at a specific time in the past will be described. Using the above-mentioned old path list table, the registration date / time (generation date / time) of the record information of the backup data file group of each transmission device is compared, and the registration date / time (generation date / time) is determined from the time (specified time) to be restored. By excluding the in-device backup data of the later record information from being restored, the in-device setting data can be restored only to the transmission device on the path of the setting path existing in the communication network at the specified time. .

  As an example, referring to the old path list table shown in FIG. 4A, based on each transmission device backup data immediately before the arbitrarily specified restoration date (for example, 2007/06/01 14: 00: 00: 00), Restore the setting data of the relevant device. This processing is performed by comparing the registration date / time and the deletion date / time with the restoration date / time in the old path list table by the batch recovery data table setting process (see the processing flow of FIG. 5), and setting data to be restored from the old path list table. Record information including the backup data file name is extracted and stored in the batch restoration data table (see FIG. 4B).

  Note that for multiple record information with the same path name, only the record information whose registration date is older than the restore date and closest to the restore date is extracted and stored in the batch restore data table, and stored in the batch restore data table. All the record information is restored in the order from the oldest registration date to the setting data of the backup data file name indicated in the record information in each transmission device.

  In the example shown in FIG. 4, the registration date / time is older than the restoration date / time 2007/06/01 14:00:00. 1-No. 59 of the record information. The record information of 1 is not subject to restoration because its deletion date / time is before the restoration date / time. No. The record information 2 is subject to restoration because its registration date is before the restoration date and its deletion date is after the restoration date.

  No. 3 and no. In the record information 59, the registration date / time is earlier than the restoration date / time and the deletion date / time is later than the restoration date / time. Only 59 is to be restored. Therefore, the batch restoration data table includes the No. of the old path list table. 2 and No. 59 record information is stored, and the setting data of the file having the backup data file name indicated in the record information stored in the batch restoration data table is set in each transmission apparatus to perform restoration. By doing so, it becomes possible to collectively restore the path setting state in the communication network at the designated date and time.

  FIG. 5 shows a flow of batch recovery data table setting processing. As shown in the figure, first, for each record information in the old path list table, it is determined whether or not the restoration date / time is earlier than the deletion date / time of the record information in the old path list table (5-1). If there is, it is determined whether the restoration date / time is later than the registration date / time of the record information of the old path list table (5-2). If it is later, the same path name already exists in the batch recovery data table. When comparing, the registration date and time of the record information of the same path name is compared, and it is determined whether or not the registration date and time of the record information in the existing batch recovery data table is older (5-3). Instead of the old record information, the record information of the new registration date is registered in the batch recovery data table (5-4). Then, it is determined whether or not all record information in the old path list table has been referred to (5-5). If all references have not been completed, the process returns to the process flow of 5-1, and the same. Repeat the process.

  If it is determined in the processing flow 5-5 that all the record information in the old path list table has been referred to, the processing ends. If it is determined NO in the process flow of 5-1, 5-2, 5-3, the process of 5-5 is performed.

  Next, the operation when the route of the working path is changed will be described. When a transmission failure occurs on the route of the current setting path in the communication network, and the setting of the working path is changed to bypass the failed route, the new working path is automatically synchronized with that timing. Thus, backup of the setting data in each device is performed.

  The above operation example will be described with reference to FIG. FIG. 6A shows a state before the occurrence of the failure, and FIG. 6B shows a state after the occurrence of the failure. In a communication network on the mesh, when setting a path, a path setting request command is transmitted to the transmission apparatuses B, C, and D that pass the current path route ((1) -1, (1) -2, (1) -3) At the same time, a backup path setting request command is transmitted to the transmission apparatuses B, E, and D that pass through the backup path route ((1) -1, (1) -4, (1) -3).

  Each transmission apparatus that has received the path setting command performs the specified path setting, and then returns an execution result to the network operation (NE-OpS) server apparatus. After receiving the path setting completion response from each transmission device, the network operation (NE-OpS) server device sends in-device setting data to each of the transmission devices B, C, D, and E that are the path setting targets. A request command is transmitted so as to back up ((2) -1, (2) -2, (2) -3, (2) -4).

  When each transmission device receives a backup request for in-device setting data, each transmission device backs up the setting data to the storage device in the own device ((3) -1, (3) -2, (3) -3, (3) -4), the backup data is transmitted as a response signal to the network operation (NE-OpS) server device 0, and the network operation (NE-OpS) server device saves and saves the backup data.

  When a failure occurs in the working path route, and the working path is automatically switched to the backup path route under the control of the network operation (NE-OpS) server device, the automatic switching is used as a trigger (that is, the working / standby mode). In synchronization with switching, the path name of the switched path is specified, and a request command is sent to the transmission apparatus on the path path of the path name so as to back up the in-device setting data ((4) − 1, (4) -2, (4) -3, (4) -4).

  Upon receiving the in-device setting data backup request command, each of the transmission devices backs up the in-device setting data in the storage device in the own device ((5) -1, (5) -2, (5) -3, Along with (5) -4), the backup data is transmitted as a response signal to the network operation (NE-OpS) server device, and the network operation (NE-OpS) server device saves and saves the backup data.

  Next, an operation when a transmission device is added or removed from the communication network will be described. After a transmission device is added or removed from a communication network that is monitored and controlled by the network operation system (NE-OpS), a path is set for the transmission device on the route via the added or removed transmission device. In synchronism with the execution of the path setting, the transmission apparatus in which the path setting has been performed is backed up in-device setting data for each path.

  The above operation example will be described with reference to FIG. FIG. 7A shows an operation example in which transmission devices are added and path information is set, and FIG. 7B shows an operation example in which backup is performed by the added transmission device. As shown in FIG. 2A, it is assumed that a path 1 and a path 2 are set in a section between the transmission apparatuses C and D (hereinafter referred to as section CD). Here, path 1 is a path of transmission apparatus A → transmission apparatus B → transmission apparatus C → transmission apparatus D, and path 2 is a path of transmission apparatus B → transmission apparatus C → transmission apparatus D → transmission apparatus E.

  When the transmission apparatus G is added to the section CD, it is necessary to set the path information of the path 1 and the path 2 for the transmission apparatus G. First, a path setting command is transmitted from the network operation (NE-OpS) server device to the transmission device G in order to set the path information of the path 1 for the transmission device G (1).

  When the execution result for the command is transmitted from the transmission device G to the network operation (NE-OpS) server device, the network operation (NE-OpS) server device backs up the in-device setting data to the transmission device G. A request command is transmitted (2).

  When the transmission device G receives a backup request for the setting data in the device, the setting data is backed up to the storage device in the own device (3), and the backup data is returned to the network operation (NE-OpS) server device, and the network The operation (NE-OpS) server device saves and saves the backup data. The above-described processing is performed for all the paths set in the section CD (in the example shown, path 2).

  The network operation (NE-OpS) server device manages the path setting information of the added transmission device by linking it with the path name, so that the setting data in the device can be stored for each path even after the transmission device is added to the communication network. It is possible to restore all at once.

  FIG. 8 shows an operation example in which the path setting information of the added transmission apparatus is managed by linking with the path name. 8A shows the current path list table before the transmission apparatus G is added, FIG. 8B shows the old path list table after the transmission apparatus G is added, and FIG. 8C shows the transmission. The current path list table after adding the device G is shown.

  As shown in FIG. 7, when the transmission device G is added to the section CD, the network operation (NE-OpS) server device sets the path information of the path 1 in the transmission device G, and the in-device setting data of the transmission device G After acquiring the backup data, the record information data of the path 1 (path name “AtoD PATH001”) of the current path list table shown in FIG. 8A is deleted in the old path list table of FIG. (2007/06/17 15:00: 00) is added and registered (4).

  Then, record information of the path 1 (path name “AtoD PATH001”) in the current path list table is changed to the backup file name “G_bk... Dat” of the added transmission device G as shown in FIG. The record information is updated (5). Similar processing is performed for all the paths set in the section CD (in the example shown, path 2).

  In this way, even if the path route is changed due to the addition of a transmission device, by managing the backup of the setting data in the device of the added transmission device linked to the original path name, the state of the latest path route can be maintained. The backup data of the in-device setting data can be managed, and the in-device setting data of each transmission device can be restored in batches on the basis of the backup data.
