[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system, such as an optical transmission system, in which a plurality of control processing devices operate according to control processing programs loaded in the control processing devices. The present invention relates to an operation information management system that manages control information necessary for operation such as information. In an information processing system including a plurality of control processing devices, the version of the device itself or the version of the control processing program is often upgraded for each control processing device. For example, each control processing device that constitutes the optical transmission system is an independent product to some extent, and the scale of the optical transmission system has been expanded or reduced by increasing or decreasing the number of control processing devices. In recent years, the life of these control processing devices as products has become longer, and in response to customer requests, products with extended functions have been developed as enhanced versions, and part of optical transmission systems has been developed. In many cases, the control processor is replaced with this enhanced version. Therefore, in one optical transmission system,
As the number of control processing devices operating with various versions of control processing programs is increasing, the version information and setting information of these control processing programs are properly managed to ensure normal operation of the entire system. The technology to do is needed.

2. Description of the Related Art FIG. 7 shows a configuration example of an optical transmission system. In FIG. 7, the transmission control unit 410 provided in the centralized control processing device 401 is connected to a plurality of control processing devices 402 via a communication line, and is used for the operation of the control processing program of each subordinate control processing device 402. It is configured to manage necessary setting information. Further, the management service processing unit 420 is connected to the console 403 via another communication line and is configured to provide an interface function with a system administrator.

The non-volatile storage section 411 provided in the transmission control section 410 described above stores setting information applied when the optical transmission system is operated, and this setting information is stored in the management service processing section 420. The data is backed up in the volatile storage unit 421 provided in the computer, and is provided for the processing according to the control processing program by the processor 422. In addition, the processor 412 provided in the transmission control unit 410
Checks the normality of the setting information and its compatibility with its own control processing program at startup according to the firmware stored in the ROM 413, and if necessary, converts the setting information and sets the setting information from one to the other. It is configured to perform copy processing.

At this time, the processor 412 first confirms the normality of the setting information in the volatile storage unit 421 based on the BCC check code stored together with the setting information, and if it is normal, controls itself. Whether or not the version of the processing program is compatible is determined, and when the normality or compatibility is denied, the setting information in the non-volatile storage unit 411 is similarly determined.

A volatile storage unit 421 and a non-volatile storage unit 41
When the normality of the setting information stored in any one of 1 and the compatibility with the version of the control processing program of the processor 412 are confirmed, the processor 412
May copy the setting information stored in the storage unit whose normality is confirmed to the other, and further notify each control processing device 402 via the communication processing unit 414 and the communication line.

In this case, the centralized control processing device 401 and each control processing device 402 of the optical transmission system can perform their respective processings by using the setting information when they were operated before as they are. On the other hand, for example, the transmission control unit 4
When the version of the control processing program 10 is changed, a version mismatch occurs between the setting information and the control processing program.

In this case, the processor 412, based on the valid setting information, the conversion table prepared in the ROM 413, and the default data, the internal RAM.
It is sufficient to create new setting information in 415.

Here, the conversion table may indicate the correspondence relationship between each unit information included in the setting information of the current version and the unit information of the setting information of the immediately previous version. In this case, as shown in FIG. 8, the processor 412 internally sets the respective unit information in accordance with the above-described correspondence regarding the setting information a and the setting information b which are the unit information indicating the correspondence with the immediately previous version. RA
The unit information peculiar to the current version may be expanded to M415, and corresponding default data may be read from the ROM 413 and expanded to the internal RAM 415 as new setting information.

As a result, in the immediately preceding version, the setting information applied when the optical transmission system was actually operated can be used as it is, and the setting information suitable for the current version can be created. Further, at this time, the processor 422 of the management service processing unit 420 notifies the transmission control unit 410 of the instruction of the user received from the console 403 via the communication line, and notifies the transmission control unit 410 of the new setting information. It can be used for the creation process.

The setting information corresponding to the current version obtained in this way is copied to the volatile storage unit 421 and the non-volatile storage unit 411, and further transferred to each control processing unit 402 via the communication line. The control processing device 402 is used for processing. On the other hand, the volatile storage unit 421
If the setting information stored in the non-volatile storage unit 411 is not normal, the processor 412
The setting information may be newly created based on the default data stored in the ROM 413.

In this case, the newly created setting information is stored in the volatile storage unit 421 and the non-volatile storage unit 411, and is provided for the processing of each control processing unit 402 via the communication line.

[0012]

The setting information applied in the above-mentioned conventional optical transmission system basically gives the highest priority to the ease of recognition in the control processing program of each version. The setting information has a unique format.

Here, although the extended version setting information inherits the setting information of the old version, in the extended version format, the setting information of the old version and the setting information unique to the extended version are: They are inseparably mixed. Therefore, with the change of the control processing program, it is indispensable to convert the format of the setting information, and the convertible version is limited by the contents of the conversion table given to show the relationship between the formats before and after the conversion. In the end, I could only convert from the previous version.

Therefore, when the setting information before the version upgrade is the old version before the convertible version, the processor 412 of the transmission control unit 410 is
Setting information is newly created using the default data prepared in the OM 413. In this case, regardless of the normality of the setting information in the volatile storage unit 421 and the non-volatile storage unit 411, the setting information applied when the optical transmission system was operated before is upgraded. Since it cannot be reflected in the setting information, normal operation operation cannot be performed in each control processing device 402, which may lead to disconnection of the main signal.

Further, the centralized control processing device 401 of the optical transmission system described above is premised on that each control processing device 402 operates according to the control processing program of the same version as itself, and the version of its own control processing program is used as a reference. As a result, the validity of the setting information is determined and the conversion processing of the setting information is performed. By the way, in an actual optical transmission system, the centralized control processing device 401 and each control processing device 402 may be individually upgraded or downgraded, and the centralized control processing device 401 and each control processing device 402 It is possible that the versions of the control processing programs do not match.

In such a case, as described above,
If the setting information suitable for the specific version of the control processing program is adopted, the control processing program of some control processing devices 402 may not be able to recognize the setting information, and normal operation should be guaranteed. I couldn't. For example, when only the transmission control unit 410 is upgraded to the new version including the extended function, in the above-described conventional setting information management system, each control processing device 402 may have the control processing program of the old version. Instead, the setting information corresponding to this new version is created and notified to all control processing devices 402.

However, in each control processing device 402, since the notified setting information cannot be used, normal operation cannot be continued and the main signal may be disconnected. As described above, the conventional setting information management system cannot cope with the change of the system configuration in the optical transmission system.

In recent years, the function of information processing systems such as optical transmission systems has become more important, and it is required to maintain the normal operation state of the information processing system regardless of whether the system configuration is changed or not. Especially,
When the system configuration is reduced such as the version down of the control processing program, it is necessary to surely provide the processing function of the reduced version.

The present invention provides an operation information management system capable of managing control information necessary for operation flexibly in response to a version change of each control processing unit in an information processing system including a plurality of control processing devices. The purpose is to

[0031]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a diagram showing an embodiment of an optical transmission system to which the operation information management system of the present invention is applied. In the transmission control unit 410 shown in FIG. 2, the setting control unit 211 has a management service processing unit 420.
In response to the input of the startup instruction from the code determination unit 21
2 and the version matching unit 213 are instructed to perform the respective processes, and the transfer processing unit 214,
Extended information extraction unit 215, new creation unit 216 and BCC
It is configured to control the operation of the code creation unit 217.

The function of each of these units is as follows:
It is realized by the processor 412 provided in the CPU 412 executing the firmware stored in the ROM 413. The default storage unit 218 provided in the ROM 413 corresponds to the extended information holding unit 114, and corresponds to each unit information included in the constant information of the basic version, as shown in FIG. 3 (a). The default information corresponding to each unit information added in each extended version is sequentially added for each version.

Further, the nonvolatile memory 219 shown in FIG.
Corresponds to the version information storage means 124 described in claim 4, and holds various hardware information and version information indicating the version of the control processing program. Further, in this case, instead of collecting the version information of the control processing programs of the transmission control unit 410 and each control processing device 402, the version information stored in the non-volatile memory 219 is used as a representative of these version information. Collator 21
The non-volatile memory 219 performs the function corresponding to the collecting means 112.

The non-volatile storage unit 411 and the volatile storage unit 421 constitute the setting information storage unit 111.
This is equivalent to one storage means 125, and the setting information applied when the optical transmission system was previously operated is B
It is stored following the CC code. This setting information is
As shown in FIG. 3 (b), in addition to a set of version information indicating a basic version and corresponding setting information, a set of version information indicating each extended version and setting information unique to the corresponding version is sequentially added. It has a configuration that
The setting information of each version is composed of setting information corresponding to each of the transmission control unit 410, the management service processing unit 420, and each control processing device 402, as shown in FIG. 3 (c).

Further, in FIG. 2, the code judging section 212
Is the BC stored in the non-volatile storage unit 411 and the volatile storage unit 421 according to an instruction from the setting control unit 211.
Based on the C code, it is determined whether or not the setting information stored in these storage units is normal, and the determination result is returned to the setting control unit 211. In addition, the version comparison unit 213 responds to the instruction from the setting control unit 211.
The latest version information stored in the non-volatile storage unit 411 and the volatile storage unit 421 is compared with the version information stored in the non-volatile memory 219, and the comparison result is returned to the setting control unit 211. ing.

Further, the transfer processing unit 214 includes the setting control unit 2
In accordance with an instruction from 11, information is mutually transferred between the volatile storage unit 421 and the nonvolatile storage unit 411 and the internal RAM 415. FIG. 4 is a flowchart showing the initial setting operation performed in response to the start-up instruction. First, in response to an instruction from the setting control unit 211, the code determination unit 212 and the version comparison unit 213 operate, and regarding the nonvolatile storage unit 411 and the volatile storage unit 421, the normality of the setting information and the compatibility of the version information. Is checked (step 301).

The setting control unit 211 has a code judging unit 212.
Based on the determination result of step S30, it is determined whether at least one of the setting information stored in the nonvolatile storage unit 411 and the volatile storage unit 421 is normal (step 30).
2). In the case of the affirmative determination in step 302, the setting control unit 211 receives the comparison result corresponding to the setting information whose normality is confirmed from the version comparing unit 213, and the setting information is transmitted to the control processing program of the transmission control unit 410. It may be determined whether or not they match (step 303).

At this time, when the version of the setting information is equal to or greater than the version indicated by the version information stored in the non-volatile memory 219, the setting control section 211 controls this setting information by the transmission control section 410. It may be determined that it matches the program. In the case of affirmative determination in step 303, the setting control unit 211 determines that the setting information of which normality is confirmed can be used as it is, and first, via the transfer processing unit 214, the version up to the version of the control processing program. The nonvolatile storage unit 411 or the volatile storage unit 421 is used as the setting information of the range in which the range can be recognized.
From the internal RAM 415 (step 3
04), the entire storage area of the storage unit of the transfer source of this setting information may be copied to the other storage unit (step 305), and the setting information may be backed up.

As described above, the transfer processing unit 214 performs the process of step 305 in accordance with the instruction from the setting control unit 211, thereby realizing the function of the copying means 126 described in claim 5, and the transmission control unit. The entire original setting information can be backed up regardless of the version of the control processing program 410. On the other hand, in the case of a negative determination in step 303, the setting control unit 211 determines that the setting information expansion processing is necessary, and at this time, the setting control unit 211
Transfers the entire setting information, the normality of which is confirmed, to the internal RAM 415 via the transfer processing unit 214 (step 3
06), and may be used for the extension processing of the setting information described later.

In this way, when the setting control unit 211 operates according to the comparison result by the version comparison unit 213 to realize the function of the extension determination unit 113 and the version of the setting information is lower than that of the control processing program. Can be detected and the setting information can be subjected to expansion processing. Next, in response to an instruction from the setting control unit 211, the extended information extraction unit 215 operates, receives the two pieces of version information to be collated from the version collation unit 213, and default information corresponding to the difference between these versions. From the default storage unit 218 (step 307), and may be stored subsequently to the setting information stored in the internal RAM 415.

For example, the setting information corresponds to version n, and the control processing program is version m (m> n).
In this case, the extension information extraction unit 215 reads out the default information corresponding to each version from version n + 1 to version m from the default storage unit 218, and sequentially stores the internal RAM 415 as shown in FIG.
You can expand it to.

As described above, the extended information extracting unit 215 operates according to the instruction from the setting control unit 211, so that the function of the extended information adding unit 115 is realized and the extended information corresponding to the version difference is leaked. It is possible to extract without adding and to add to the original setting information, and it is possible to create the setting information corresponding to the extended version. Further, this makes it possible to easily create the setting information suitable for the control processing program while effectively using the original setting information regardless of the combination of the version of the original setting information and the version of the control processing program. it can.

Next, the setting control unit 211 controls the transfer processing unit 2
The setting information including the extension information stored in the internal RAM 415 is transferred to the non-volatile storage unit 411 via 14 (step 308), and the BCC code creation unit 217 executes the BCC.
It can be used for code creation processing. At this time, as shown in FIG. 5, the transfer processing unit 214 expands the setting information stored in the internal RAM 415 into a storage area having a predetermined address of the nonvolatile storage unit 411 as a start address, and the transfer processing is also performed. In response to the end notification of
For the BCC code creation unit 217, the entire corresponding storage area including the unused area may be designated as a code creation target.

In response to this, the BCC code creating section 217
Operates as the code creating means 116 described in claim 2, creates a BCC code for the specified storage area of the non-volatile storage unit 411 (step 309), and starts the above-mentioned predetermined address from the top of the non-volatile storage unit 411. It may be expanded to the storage areas up to (see FIG. 5). Here, in step 309 described above, the BCC code creation unit 21
In No. 7, the storage area in which the original setting information and the extension information are expanded and the unused area are also targets of BCC code creation. Therefore, regardless of the data lengths of the setting information and the extension information, this BCC code creating unit 2
According to 17, a BCC code having a fixed code length can be obtained as an error check code.

By thus setting the length of the error check code to be constant, the BCC code creating section 21
7 and the code determination unit 212, it is possible to eliminate the need to be aware of the size of the storage area of the code creation target and the length of the error check code.
The configurations of the code creation unit 217 and the code determination unit 212 can be simplified to simplify the firmware.

After that, the setting control unit 211 may copy the entire storage area of the non-volatile storage unit 411 to the volatile storage unit 421 via the transfer processing unit 214 (step 310) and back up the setting information. On the other hand, the volatile storage unit 4
21 and the setting information in the non-volatile storage unit 411 are both not normal (negative determination in step 302)
Is created by the new creation unit 2 in response to an instruction from the setting control unit 211.
16 operates, and setting information suitable for the version of the control processing program may be newly created based on the default information in the default storage unit 218 (step 3).
11).

At this time, the new creation section 216 may sequentially read all the default information up to the version indicated by the version information held in the non-volatile memory 219 from the default storage section 218 and expand it in the internal RAM 415. Then, the process proceeds to step 308, the newly created setting information is expanded in the non-volatile storage unit 411,
Furthermore, a BCC code corresponding to this setting information may be created and copied to the volatile storage unit 421 to back up the setting information (steps 309 and 310).

After completion of step 305 or step 310 described above, the communication processing unit 414 sends the setting information expanded in the internal RAM 415 to the communication line in accordance with an instruction from the setting control unit 211 to perform each control. It suffices to notify the processing device 402 and the management service processing unit 420 (step 312) and end the initial setting process. At this time, the communication processing unit 414 extracts the setting information corresponding to each control processing device 402 and management service processing unit 420 from the internal RAM 415, and each control processing device 402.
It may be sent as a message addressed to the management service processing unit 420.

As described above, when the operation information management system of the present invention is applied, the centralized control processing device 401 and each control processing device 402 that constitute the optical transmission system may be changed individually or by changing the configuration. , Even if there are cases where devices that operate with multiple versions of the control processing program coexist in the optical transmission system, if the setting information that was applied in the previously operating state remains in a normal state, This setting information is saved as part of the new setting information.

Therefore, the configuration of the optical transmission system can be freely changed according to the customer's request, and the setting information can be appropriately managed in various system configurations. It can prevent the occurrence. Particularly, by applying the invention of claim 5 and backing up all the information stored in one storage means 125 constituting the setting information storage means 111 to the other storage means 125, the control processing of the transmission control unit 410 Even when the version of the program is downgraded, it is possible to save the setting information corresponding to the higher version and be prepared for the subsequent version upgrade.

Before starting the above-described initialization processing, each control processing device 402 inquires the version of each control processing program via the communication processing unit 414, and is obtained as a response from each control processing device 402. If the version information is provided to the process of the version comparison unit 213 instead of the version information of the non-volatile memory 219, the setting information can be created in consideration of the versions of all the devices configuring the optical transmission system.

For example, from the version information collected as described above, the one indicating the most expanded version is detected, and the expansion information corresponding to each version up to the latest version is added to create the setting information. Good. By the way, as described above, since the setting information unique to each extended version is sequentially added to the setting information of the basic version, the processors of the centralized control processing device 401 and each control processing device 402 are respectively loaded. It is possible to easily know the range of the setting information corresponding to the version of the control processing program and use it for the transmission control processing by each.

However, if the centralized control processing device 401 and each control processing device 402 operate with different versions of the control processing programs, normal operation of the entire optical transmission system may not be guaranteed.
Next, a method for guaranteeing normal operation of the optical transmission system based on the setting information obtained as described above will be described.

FIG. 6 shows a block diagram of an optical transmission system to which the operation information management system of claim 3 is applied. In the transmission control unit 410 shown in FIG. 6, the version collection unit 231
Via the communication processing unit 414, each control processing device 402
The version information is collected from the management service processing unit 420 and is used for the process of the operation version determining unit 232 together with the version information held in the nonvolatile memory 219.

Further, each control processing device 402 shown in FIG.
In the management service processing unit 420, the non-volatile memory 233 corresponds to the version information storage means 124 described in claim 4, and the non-volatile memory 2 described above.
Similar to the reference numeral 19, version information indicating the version of the corresponding control processing program is stored together with various pieces of hardware information.

Further, the version notifying unit 234 provided in each control processing device 402 receives the instruction from the above-mentioned version collecting unit 231 via the communication processing unit 235, and correspondingly stores it in the non-volatile memory 233. The version information is read out and returned to the requesting transmission control section 410 via the communication processing section 235. In this way, the version collection unit 231 provided in the transmission control unit 410 and the version notification unit 234 provided in each control processing device 402 exchange version information via the corresponding communication processing units 414, 235. By doing so, it is possible to realize the function of the collecting means 112 described in claim 3 and collect the version information of the control processing program loaded in each device constituting the optical transmission system.

Further, in FIG. 6, the operation version determination unit 232 corresponds to the operation determination means 118, and determines the operation version on which all the control processing devices 402 can operate based on the received version information. It is composed. This operation version determination unit 232
May detect the lowest version from the received version information and use this version as the working version.

The operation version determined in this way is used for controlling the control processing program in its own apparatus, and is also notified to each control processing apparatus 402 via the communication processing section 414 to notify each control processing apparatus 402.
