Description

  The present invention relates to a data processing system that performs communication control processing and the like according to various setting data, and a diagnostic method that checks the validity of setting data for performing the data processing.

  A system that performs communication control processing of high-speed data of about 10 Gbps using an optical signal or an electric signal has been put into practical use. In such a system, for example, a data transmission / reception processing unit using an optical signal or data using an electric signal is used. When the transmission / reception processing unit is mounted as a module or package, and this is a lower-level device, setting data for processing operation of each unit is set in the register of the lower-level device from the higher-level device, and transmission / reception processing is performed. In a relatively large-scale system, for example, a program corresponding to the processing operation on the 10 Gb-E side in the Ethernet (registered trademark) in the lower level apparatus and the OC192 side in the SONET (Synchronous Optical Network), etc. It is common to develop In this case, for example, a system in which a plurality of higher-level devices for performing setting control corresponding to processing operations of the lower-level devices are provided and the setting data is written from the higher-level devices to the registers of the lower-level devices so that modification or the like is easy Are known. The subordinate device performs a processing operation based on the setting data written in the register. Therefore, it is necessary that the setting data is normal. Therefore, the checksum of the setting data is obtained, and the checksum is stored in the register together with the setting data. When the setting data is read from the register and checked, the checksum of the read setting data is obtained and saved with this checksum. A method is known in which the checksum is compared and the normality of the set data is confirmed by comparison and matching.

When setting data is written to the memory, the setting data and the address are temporarily stored in the memory. When the setting data has been written, the setting data previously written to the memory is stored using the stored address. Read and verify with the temporarily stored setting data, save the verification result in the register, read the verification result from the register when the writing of all the setting data is completed, write the setting data normally Means for confirming whether or not it has been proposed has been proposed (for example, see Patent Document 1).

  In general, a method for checking transferred data by adding a parity check bit of the data or adding a check bit such as CRC so that the normality of the data can be checked is generally known. . Therefore, it is possible to add the parity check bit or the CRC check bit to the setting data and write it to the register, read the setting data, and check the normality of the setting data using the parity check bit or the CRC check bit. In this case, it is possible to check whether or not there is a bit error, but it is impossible to check whether or not the setting data has a desired content. In addition, as described above, the data checksum is obtained and stored, and in the case of data normality confirmation, the data checksum is obtained and collated with the previously stored checksum. Sex can be confirmed. Also in this case, it is impossible to check whether or not the setting data maintains the desired content.

  In a comparatively large-scale communication control system including a higher-level device such as a plurality of types of control units corresponding to a control function for a single or a plurality of communication processing units that perform communication control processing as a lower-level device.

For this reason, there is a case in which the setting data held in the register is overwritten by setting data from a higher-level device other than the higher-level device that is first set by transferring the setting data for the lower-level device. In this case, it is possible to check whether or not there is a bit error with only the checksum, but it becomes impossible to check the validity of the setting data, and there is a problem that data processing cannot be executed normally. For example, in a configuration in which multitask processing is executed, setting data may be overwritten in the same register multiple times asynchronously by a plurality of tasks. Similarly, setting data to be written to a register of a lower-level device such as the same transmission / reception unit may be changed according to each request from a higher-level device such as a plurality of control units. In such a case, it is difficult to check whether or not the setting data is valid, and the more the setting data pattern is, the more difficult it is to check.

  Also, there are cases where the setting data written to the register is not valid. (1) When setting data is written continuously before the wait time, it becomes a wait time in the middle, causing a problem due to write leakage. (2) Momentary voltage drop (3) Problems due to setting omission due to congestion of wait request processing messages, (4) Problems due to lack of validity due to overwriting of setting data, (5) Multiple problems There are problems such as inconsistencies in setting data due to setting requests from the apparatus, and there is a problem that data processing such as normal communication control cannot be performed due to these problems.

  FIG. 1 is an explanatory diagram of a first embodiment of the present invention, showing a main part when applied to a communication control system as a data processing system, wherein 1 is a setting data processing unit, 2-1 is a control unit # 1 (Communication function unit) 2-2 is a control unit # 2 (OC192 control unit), 2-3 is a control unit # 3 (10 GbE control unit), 11 is a register, 12 is a hardware access unit, 13 is a database, 14 Is a set address list, 15 is a received message list, 16 is a table, 21-1 to 21-3 are package interface units, 22-1 is a communication control unit, 22-2 is an OC192 control unit, and 22-3 is a 10 GbE control unit. 23-1 is a communication control database, 23-2 is an OC192 attribute database, 23-3 is a 10GbE attribute database, and data transmission processing is performed at a transmission rate of 10Gbps. It shows the case cormorant. The control units # 1 to # 3 will be described below as the control units 2-1 to 2-3 or the communication function unit 2-1, the OC192 control unit 2-2, and the 10 GbE control unit 2-3 as different host devices. . Further, between each of the control units 2-1, 2-2, 2-3 and the setting data processing unit 1 as a subordinate device, the setting data processing unit 1 from each of the control units 2-1, 2-2, 2-3. Although a path for inputting a register setting request to the hardware access unit 12 is illustrated, response information or the like is sent from the setting data processing unit 1 to each of the control units 2-1, 2-2, 2-3. It has a route to transfer, and the route is not shown.

  The setting data processing unit 1 includes a register 11, a hardware access unit 12, and a database 13. The database 13 has a configuration including a setting address list 14, a received message list 15, and a table 16. Although a lower-level device such as a communication processing unit that performs communication control processing according to the setting data held in the register 11 is not shown, a single or a plurality of lower-level devices can be provided. Also, the control units 2-1, 2-2, 2-3, and maintenance not shown in the figure are held for the setting data and addresses held in the setting address list 14, the received message list 15 and the table 16 of the register 11 and the database 13. Compared with a determination unit for comparing in accordance with an instruction from a higher-level device such as a device, a unit for notifying a higher-level device or the like of the comparison result, and a means for writing and reading data, etc. Omitted. These means can be realized by processing means such as a processor already known.

  The hardware access unit 12 receives a reception message such as a register setting request from a host device such as the control units 2-1, 2-2, 2-3, and controls access to the register 11 and access control to the database 13. It has a function to perform. The table 16 is provided so that various commands from the host device can be applied to a system configuration in which the access address of the register 11 is added and the command address is not added. The table 16 forms a correspondence table for obtaining an address based on the contents of a command when an access address for the register 11 is not added to a received message such as various commands from the host device. For example, in the case of a command for setting the amplification factor of the output amplifier of the low-level device from the high-level device, an address corresponding to the low-level device for setting the amplification rate can be determined in advance in the register 11. By forming a correspondence table in which the addresses are associated with each other in the table 16, the access address for the register 11 can be obtained from the table 16 even for a command to which no access address is added. In addition, the correspondence table may include a setting value (setting data) together with an address. As a result, even if no access address is added when a command from a higher-level device such as the control units 2-1, 2-2, 2-3 is transferred to the hardware access unit 12, The access address of the register 11 can be obtained.

  For example, when a register setting request message for setting setting data for the lower apparatus from the upper apparatus to the register 11 is transferred to the hardware access section 12, the hardware access section 12 transmits the address of the register 11 and the setting value. If the setting request is added with (setting data), the setting value is written in the register 11 and the reception request is registered in the database 13 according to the address. That is, the access address and the setting value (setting data) for the register 11 are held in the setting address list 14 of the database 13 so that the address relationship indicated by the arrows can be understood, and the received message list 15 has, for example, “ The contents of the register setting request message are held as indicated by register setting # 1 "and the like. In this case, the register setting request includes the name of the control unit as the requesting higher-level device or an identifier indicating the control unit, and the received message list 15 includes data that can identify the requesting source. In the case of a register setting request message to which the access address of the register 11 is not added, the hardware access unit 12 searches the table 16 based on the contents of the register setting request message as described above, and An access address is obtained, and a set value can be written in the register 11 according to the access address. The set address list 14 and the received message list 15 include the address of the register and hold necessary contents respectively.

  The control unit 2-1 controls a communication function as a communication control system. The package interface unit 21-1 performs data transfer with the setting data processing unit 1, and the communication control unit 22-. 1 and a communication control database 23-1.

The control unit 2-2 has a configuration including a package interface unit 21-2, an OC192 control unit 22-2, and an OC192 attribute database 23-2. The OC192 attribute database 23-2 includes a lower level device. A control unit for holding a register setting request message for setting setting data in the register 11 and transmitting data with an optical signal at a transmission rate of 10 Gbps in the transmission / reception unit of the lower apparatus is shown. The control unit 2-3 has a configuration including a package interface unit 21-3, a 10 GbE control unit 22-3, and a 10 GbE attribute database 23-3. 11 holds a register setting request message for setting the setting data, and changes the setting data according to the setting change request from the maintenance operation management means. 2 shows a control unit as a host device when data is transmitted at a transmission rate of 2. In systems using other data transmission systems and data processing systems that process various types of data, a control unit can be provided as a host device corresponding to the data transmission system. A host device corresponding to the aforementioned plurality of control units that set corresponding setting data in the lower device is provided. In FIG. 1, the setting data to be set in the lower apparatus is set by a register setting request from the control units 2-1 to 2-3 of the upper apparatus, but is set according to the request from the lower apparatus. Data can be transferred from the host device and set in the register 11.

  FIG. 2 is an explanatory diagram of a main part of the first embodiment of the present invention, in which the setting data processing unit 1 includes a register 11, a hardware access unit 12, a table 16, and a control processing unit 18. The setting address list 14 and the received message list 15 in FIG. 2 is a control unit collectively showing the control units 2-1, 2-2 and 2-3 in FIG. 1 as a host device, 31 is an OC192 optical module, 32 is a transmission frame section overhead termination process, etc. An overhead processing unit, 33 is a 10.7G side optical module, 35 is an HDLC (High Level Data Link Control) termination circuit, 36 is an optical splitter, 37 is an optical switch, and 10 is a data transmission process as a subordinate device including them. Indicates the device. Further, the control unit 2 which is the host device of the data transmission processing device 10 as the lower device is, for example, the communication function unit (control unit # 1), the OC192 control unit (control unit # 2), or the 10 GbE control unit in FIG. A case where the control units 2-1, 2-2, 2-3 such as (control unit # 3) correspond is shown.

  The optical splitter 36 is a splitter for transmitting the same optical signal from the east side and the west side to a double ring optical transmission line (not shown), and the optical switch 37 is connected to the east side. This is a switch for selecting and receiving either one from the waist side or the normal side. Note that the optical switch 37 shows a case where one side is selected in accordance with the setting data of the register 11. In addition, the control processing unit 18 includes a function for setting and processing the respective operating conditions of the OC192 optical module 31, the overhead processing unit 32, and the optical module 33 in accordance with the setting data of the register 11. For example, the OC192 control unit 2-2 as the host device writes the setting data for the OC19 optical module 31 in the data transmission processing device 10 as the lower device to the register 11, and the 10GbE control unit 2-3 as the host device. Will write the setting data for the optical module 33 in the data transmission processing device 10 as the lower device to the register 11. In this way, setting data from a plurality of higher-level devices is set in the register 11 of the data transmission processing device 10 as a lower-level device, and communication processing control is performed. Also, in the case of a general data processing device, each higher-level device with respect to the lower-level device sets the setting data according to the different control processing contents in the lower-level device in the lower-level device register. Control processing according to the data is executed.

  FIG. 3 is an explanatory diagram of a diagnostic function when applied to the communication control system shown in FIG. 1 as the data processing system according to the first embodiment of the present invention. The same reference numerals as those in FIG. 1 denote the same parts. The self-recovery necessity determination unit of the control unit 2-3 can be provided in a control processing function unit such as the 100bE control unit 23-3. The communication function unit 2-1 and the OC192 control unit 2-2 are also provided with this self-recovery necessity determination unit. The setting data held in the register 11 from a maintenance console (not shown) in a state where the setting data has been written from the respective control units 2-1, 2-2, 2-3 of the upper apparatus to the register 11 of the lower apparatus. In this example, the validity of the setting data written in the register 11 is checked by inputting a test command for checking the validity of. In this case, the setting address list 14 of the database 13 holds the address of the register 11 in which the setting data is written and the setting data as described above, and the arrows indicate the address of the register 11 and the setting address list. 14 exemplifies the correspondence with the address held in 14, and the value of the setting address list 14 is the same value as the setting data written in the register 11 or a predetermined effective bit in the setting data. For example, the address “420,000” of the register 11 and 16-value display “01” as setting data are stored in association with each other, and the address “420002” of the register 11 and “08” of the setting data are stored. "Is shown in correspondence with each other.

  The received message list 15 holds received messages from the control unit as the host device, and the contents include “control unit”, “command”, “AID”, “parameter 1”, “parameter 2”, and the like. As an example, the “control unit” indicating the host device is “10 GbE”, “command” is “ENT-10GE”, “AID” is “1”, and “parameter 1” is “AISPT = LF”. “Parameter 2” indicates a case where “ALMXFDLY = 100” is held. The “parameter” includes a larger number of cases, and the “control unit” indicates the name of the control unit indicating the 10 GbE control unit 2-3, but may be an identifier indicating the control unit. it can. “AID” indicates an identifier (ID) such as a unit port number or an interface. “Parameter 1” “AISPT = LF” indicates an example of attribute information about AIS (Alarm Indication Signal), and “Parameter 2” “ALMXFRDLY = 100” indicates an example of attribute information of alarm detection delay time. Show. In addition, the single or plural areas (addresses) of the received message list 15 that holds the received message corresponding to the control unit, and the areas (addresses) that hold the address of the register 11 and the setting data held in the setting address list 14 , A relationship as schematically shown, for example, the area holding the addresses “420,000”, “420002”, “420004” of the register 11 has a corresponding relationship with “10 GbE” of the “control unit” of the received message list 15. It is. This address correspondence is held in the list 16.

  When a test command is input to the hardware access unit 12 of the setting data processing unit 1 from a maintenance console (not shown), the setting data in the setting address list 14 held and managed in the database 13 and held in the register 11 The setting data being compared is compared as shown as a setting state difference check. In this case, for example, the setting data is sequentially read from the head address of the register 11, and the setting data held in the setting address list 14 corresponding to the address is read and compared. Alternatively, the setting data can be read from the corresponding address of the register 11 and compared based on the address held in the setting address list 14. When a part of the setting data is held as a valid bit in the setting address list 14, the valid bits of the setting data read from the register 11 are compared. If a difference is detected as a result of this comparison, the setting request source can be extracted by referring to the received message list 15 corresponding to the address. For example, when a difference is detected with respect to the setting data of the addresses “420,000” and “40004” of the register 11, the control unit as a higher-level device that has made a setting request for these addresses is referred to the received message list 15. Determine. In the illustrated case, since the setting request source holds “10 GbE” as the “control unit”, it is understood that the setting request source is the 10 GbE control unit 2-3. Therefore, a mismatch notification is given to the 10 GbE control unit 2-3 as the setting request source as indicated by a one-dot chain line. This notification can be performed through a connection path such as a LAN (not shown) between the setting data processing unit 1 and the 10 GbE control unit 2-3.

  Upon receiving the inconsistency notification, the control unit 2-3 determines necessity by the self-recovery necessity determination unit of the 10 GbE control unit 23-3. In that case, the 10 GbE attribute database 22-3 stores a message including setting data when a setting request is made. Further, the self-recovery necessity determination means by the processing function of the 10 GbE control unit 23-3 refers to the 10 GbE attribute database 22-3 and determines whether the recovery process is necessary. When the recovery process is necessary, the register access request message stored in the 10 GbE attribute database 22-3 is used again to the hardware access unit 12 of the setting data processing unit 1 through the package interface unit 21-3. Make a register setting request. Thereby, the setting data can be overwritten to correct the error in the setting data. This self-recovery necessity determining means is notified of the setting data in which a difference has occurred together with the inconsistency notification from the setting data processing unit 1, and can therefore be performed according to a determination condition according to the nature of the setting data. For example, if the setting data has a property of having a value within a certain range, it can be determined that self-recovery is not necessary if the setting data is inconsistent within that range. If the inconsistency is not acceptable at all, it is determined that self-recovery is necessary based on the inconsistency notification, and a register setting request is sent to the setting data processing unit 1 as described above. Thereby, the set value of the register 11 can be corrected to a correct value.

  FIG. 4 shows a flowchart of the diagnosis process in the communication control system according to the first embodiment of the present invention by steps (A1) to (A10). The validity of the setting data is checked from a host device such as a maintenance console. When the test command for performing the test is input to the hardware access unit 12 of the setting data processing unit 1 (A1), the setting data processing unit 1 acquires the setting value (A) corresponding to the address from the setting address list 14 of the database 11. (A2), the register value (setting value) (B) written to the address from the register 11 is acquired (A3), the acquired setting values (A) and (B) are compared (A4), and if they do not match The received message list 1 based on the address where a difference is detected between the set values (A) and (B), as shown as reverse conversion (A5) from the corresponding address to the message. Searching, indexing the corresponding control unit performing the setting request from the message (A6), performs mismatch notification to the control unit (A7). In that case, the setting request control unit can be determined by reading the control unit name corresponding to the address held in the setting address list 14 or the identifier indicating the control unit. Then, it is determined whether or not all addresses are finished (A8). If not finished, the process proceeds to step (A2). If finished, this process is finished. If the set values in the step (A4) match, the process proceeds to step (A8).

  The control unit that has received the inconsistency notification determines whether self-recovery is necessary by self-recovery necessity determination means (A9). If it is determined that it is not necessary, the process is terminated. If it is determined that it is necessary, a register setting request is sent to the setting data processing unit 1 to terminate the process, as shown in Reset execution (A10). . The determination of the necessity of self-recovery is based on the setting value held in the control unit database and the nature of the setting value as described above. For example, there is a setting value. If it is necessary to be a value, it is determined that self-recovery is necessary by notification of inconsistency, and if there is no operational problem if the set value is within a certain range, for example, the gain of the transmission amplifier of the transmission / reception unit The set value is generally set within a certain range for the system. In that case, if the set value is within the set range, it is determined that self-recovery is unnecessary and set. If the setting value is out of the range, it is determined that self-recovery is necessary. If it is determined that self-recovery is necessary in this way, the reset processing of the register 11 is performed, and the register 11 is set. Reliability of set values It can be improved.

  FIG. 5 is an explanatory diagram of a diagnostic function according to the second embodiment of the present invention. The same reference numerals as those in FIG. 1 denote the same parts, and 17 denotes a test command received message list. The test command received message list 17 is formed in the database 13. However, as shown in the figure, it can be formed using a memory different from the database 13. In the second embodiment, register setting test commands are input to the control units 2-1 to 2-3 from the maintenance console or the like, so that the control units 2-1 to 2-3 are connected to the setting data processing unit 1. In this example, a test command register setting request including the contents of the register setting request commands held in the databases 23-1 to 23-3 is input. The hardware access unit 12 of the setting data processing unit 1 The register setting request test command is received and identified, and a test command received message list 17 is created in the database 13. Alternatively, as described above, the test command received message list 17 is formed in a memory different from the database 13.

  The contents of the test command received message list 17 and the received message list 15 are compared, and a notification of the comparison result is sent to the control unit or the maintenance console or the like that has sent the register setting request for the test command from the setting data processing unit 1 Send to host device. Also in this case, the result notification including the difference information of the comparison result can be transmitted. Accordingly, since the contents of the received message list 15 corresponding to the contents at the time of register setting request from the control units 2-1 to 2-3 are compared with the contents of the test command received message, message omission and message contents It is possible to confirm the presence or absence of changes. The control units 2-2 to 2-3 having received the notification of the message omission or content change can write correct setting data in the register 11 by making a reset request to the setting data processing unit 1. Reliability of system operation management can be improved.

  FIG. 6 is a flowchart of the diagnostic processing according to the second embodiment of the present invention. When a test command is input to the control unit (B1), a test command register setting request is sent from the control unit to the setting data processing unit 1. (B2). The setting data processing unit 1 creates a test command received message list 16 (B3), and compares the test command received message list 17 with the received message list 15 (B4). In the case of comparison coincidence, it is determined whether or not the comparison processing for all of the received message list 15 has been completed (B6). If the comparison has been completed, the processing is terminated, and if not compared, step (B4). Migrate to If the comparison result in step (B4) does not match, the content of the mismatch is sent as a comparison result notification to the control unit or the host device (B5). The control unit that has received the notification of the comparison mismatch result makes a register setting request again based on the register setting request message including the setting data held in the database in the control unit, and updates the setting contents of the register 11. The register 11 can hold correct setting data.

  FIG. 7 is an explanatory diagram of a diagnostic function according to the third embodiment of the present invention. The same reference numerals as those in FIG. 1 denote the same parts. The third embodiment prevents erroneous overwriting when setting data is written to the register 11 during system operation. For example, as shown in FIG. When the data is sent to the hardware access unit 12 of the setting data processing unit 1, the hardware access unit 12 temporarily registers the received message of the register setting request content as shown in the database 13 as temporary reception request registration. In the illustrated case, the temporary registration is performed in a part of the received message list 15, for example, “communication control” (communication function unit 2-1) in the “control unit” column and “ED−” in the “command” column. “LAN”, “AID” are registered as “1”, and “Parameter 1” are registered as “IS” as shown as an example. In this case, temporary registration contents associated with the address of the register 11 are used.

  Then, when the register 11 is searched based on the address of the temporarily registered received message and the setting data is written in the register 11 having the same address, the register 11 is overwritten by the setting data based on the received message. When the occurrence of the overwriting is detected, an overwriting notification is sent to the control unit that has made the register setting request. In the case shown in the figure, a normal register setting request is sent from the control unit 2-1 to the setting data processing unit 1, and an overwriting notification is sent from the setting data processing unit 1 to the control unit 2-1 due to address duplication. The control unit 2-1 determines whether self-recovery is necessary by the self-recovery determination unit of the communication control unit 23-1 based on the overwrite notification. If self-recovery is required as a result of this determination, a forced register setting request is made. As a result, the setting data processing unit 1 performs the overwrite process on the register 11 based on the received message temporarily registered in the received message list 15, and sets the contents of the register 11 according to the request of the control unit 2-1. Can do.

  FIG. 8 shows a flowchart of the diagnostic process according to the third embodiment of the present invention. When the setting data processing unit 1 receives a normal register setting request in the register setting request reception waiting (C1) state, As shown as temporary registration (C2), the received message is temporarily registered in the database 11. Next, the setting address list 14 is searched using the address corresponding to the temporarily registered register setting request as a key (C3), and the presence / absence of a duplicate address is determined (C4). If it is determined that there is a duplicate address, a hardware overwrite notification indicating that the register 11 is overwritten is sent to the requesting control unit (C5). If it is determined that there is no duplicate address, the temporary registration is changed to formal registration (C6), and the writing process to the register 11 is performed.

  In addition, the control unit that has received the hardware overwrite notification in step (C5) determines whether self-recovery is necessary, and ends the process if it is not necessary. If the determination is necessary, a reset request issuance (C8) is made and a forced register setting request is made. Thereby, setting to the register 11 by other control units can be avoided, and the validity of the setting data set in the register 11 can be ensured. When it is determined that self-recovery is not required by the hardware overwrite notification and nothing is notified to the setting data processing unit 1, the setting data processing unit 1 deletes the provisional registration contents to avoid overwriting. Therefore, it is possible to continue the stable operation of the communication control system while maintaining the validity of the setting data without changing the contents held in the register 11 by erroneous setting data.
