Description

  The present invention relates to a server system of an operation system that includes a plurality of client systems and a server system and that monitors and controls a plurality of network components that constitute a communication network.

  2. Description of the Related Art Conventionally, network components such as transmission devices constituting a network are managed and controlled by an operation system.

  FIG. 1 shows a configuration diagram of an example of an operation system. In the figure, an operation system (OpS) 10 receives a service request for monitoring / control from an operator, and executes a plurality of client systems 11a, 11b for displaying a screen, and a service request received by the client systems 11a, 11b. The server system 12 is configured.

  A plurality of transmission apparatuses 13-1 to 13-8 to be monitored and controlled by the operation system 10 are network components (NE) and constitute a communication network 14. The monitoring network 15 connects the operation system 10 and the transmission devices 13-1 to 13-8 of the communication network 14 to each other. Although the transmission apparatuses 53-1 to 53-8 are shown in the figure, the number of transmission apparatuses is actually eight or more.

  In the conventional operation system, when the server system 12 receives an alarm from any of the transmission devices 13-1 to 13-8, all client systems 11a and 11b connected to the server system 12 regardless of the type of alarm. The alarm is notified.

  The alarms from the transmission devices 13-1 to 13-8 are notified from the server system 12 to the client systems 11a and 11b, regardless of whether the alarm is caused by the control execution or the alarm generated due to the failure. A transitional alarm generated at the time of setting a path is also notified to the client systems 11a and 11b in the same way as a normal alarm.

Note that Patent Document 1 relates to a transmission device and an alarm monitoring device, which is provided in the middle of an alarm transmission path from a failure detection means of the transmission device to a monitoring control device, and is detected when sub-traffic is dropped from a standby transmission line. It has been described that it has an alarm protection means for masking alarms related to the detected fault.
JP 2001-230762 A

  In recent years, as the performance of the server system 12 is improved, the number of transmission devices that are monitored and controlled by one operation system 10 tends to increase. Therefore, the number of alarms per server system processed to notify the client systems 11a and 11b is also increasing.

  Among the alarms of the respective transmission devices that are notified and displayed to all the client systems 11a and 11b, there are a large number of alarms that are unnecessary for the network administrator, that is, alarms that do not directly affect the operation of communication.

  For example, the transitional alarm generated by path setting work is used only by the path setting worker to confirm the normality. Therefore, only the path setting worker needs to be confirmed. The alarm generated by the transmission device control is It is an alarm that only needs to be confirmed by an operator who controls the transmission device. Further, alarms such as an alarm issue test before the start of operation of the transmission line are alarms that only need to be known by the operator.

  As described above, since necessary alarms differ depending on workers, there is a problem in that it is not possible to easily determine necessary alarms in the conventional method in which all alarms are displayed on the client. .

  The present invention has been made in view of the above points, and provides a server system of an operation system that can notify only an alarm required for each client system and easily determine the alarm in each client system. The overall purpose is to do.

In order to achieve this object, a server system of an operation system according to the present invention includes a plurality of client systems and a server system, and monitors and controls a plurality of network components constituting a communication network.

<First embodiment>
FIG. 8 shows a block diagram of an operation system for explaining the first embodiment of the present invention. In the figure, the operation system includes a plurality of client systems 51 a to 51 c that receive a service request for monitoring and control from an operator and display a screen, and a server system 30.

  A plurality of transmission apparatuses 53-1 to 53-8 to be monitored and controlled by the operation system are network elements (NE) and constitute a communication network 54. The monitoring network 55 connects the server system 30 and the transmission devices 53-1 to 53-8 of the communication network 54 to each other. Although the transmission apparatuses 53-1 to 53-8 are shown in the figure, the number of transmission apparatuses is actually eight or more.

  FIG. 9 shows a flowchart for explaining the first embodiment of the present invention.

  In step S1, the server system 30 receives an alarm from the transmission device 53-7 (# 7) by the NE communication unit 33 and notifies the intelligent alarm processing unit 34 of the alarm. The intelligent alarm processing unit 34 refers to the intelligent database 40 using the alarm transmission device, occurrence site, and alarm type, and whether the alarm received in step S2 is subject to notification-limited processing (whether there is a record in the intelligent database 40). Judging. In the intelligent database 40 shown in FIG. 5, since the record for the transmission device 53-7 (# 7) is on the 12th line, this alarm is a target of the notification limiting process.

  In the case of a notification-limited target alarm, intelligent information (intelligent database 40 record itself: alarm additional information) is added to the alarm information and registered in the alarm database 39 in step S3, and the client communication unit management unit 35 is notified in step S5. To do.

  The client communication management unit 35 sends an alarm information notification to the target client communication unit (for example, 31-1) based on the received alarm information and the target client in the intelligent information, thereby limiting the client system 51a to the alarm. Information can be notified. As a result, only the client system 51a shown in FIG. 8 is displayed that a signal interruption alarm has occurred in the transmission device 53-7.

  On the other hand, if the received alarm is an alarm that is not subject to notification limitation (ordinary alarm), the client information is registered in the alarm database 39 in step S4, and the client communication unit management unit 35 is notified in step S5.

  As a result, the client communication management unit 35 notifies the alarm information to all the client communication units 31-1 to 31-8. Therefore, alarms for which notification-limited alarm information is not created in the intelligent database 40 are displayed on all client systems 51a, 51b, 51c as before.

<Second Embodiment>
FIG. 10 shows a block diagram of an operation system for explaining the second embodiment of the present invention. In the figure, the same parts as those in FIG.

  FIG. 11 shows a flowchart for explaining the second embodiment of the present invention.

  When the server system 30 receives the control request from the client system 51d by the communication unit for clients (for example, 31-2), the server system 30 transmits a control execution request to the control unit 32. In step S11, the control unit 32 that has received the control execution request transmits a command transmission request to the NE communication unit 33 (step S12). At the same time, the knowledge database 42 and the configuration database 43 are referred to, an expected occurrence alarm for the control content is acquired, and notification limited alarm information is created in the intelligent database 40.

  For example, in the case of a control execution request (SW_WORK) for switching the transmission path between the transmission apparatuses 53-1 and 53-2 from the working path to the backup path, the contents of the knowledge database 42 and configuration database 43 are used to determine the transmission apparatus 53-1. It is expected that an alarm (SW_WORK) will occur at the part HS-1-1 of the part HS-2-1-1 and the part HS-1-1-1 of the transmission apparatus 53-2, and the first and second lines of the intelligent database 40 shown in FIG. On the line, records for the transmission apparatuses 53-1 (# 1) and 53-2 (# 2) are generated.

  Here, the setting client and the target client are the same. However, if a group ID is specified in the control execution request, the target client is set to NULL (invalid) as shown in the first and second lines of the intelligent database 40 in FIG. Sets the group ID specified in the control execution request. As a result, the group ID in the group database 41 and the group ID in the intelligent database 40 can be linked.

  When an alarm is received from the transmission device, the processing is the same as that in FIG. That is, in step S13, the server system 30 receives an alarm from the transmission devices 53-1, 53-2 by the NE communication unit 33 and notifies the intelligent alarm processing unit 34 of the alarm. The intelligent alarm processing unit 34 refers to the intelligent database 40 using the alarm transmission device, the occurrence site, and the alarm type, and determines whether the received alarm is a notification-limited process target (whether there is a record in the intelligent database 40). (Step S14).

  In the case of a notification limitation target alarm, intelligent information (the record itself of the intelligent database 40: alarm additional information) is added to the alarm information and registered in the alarm database 39 in step S15, and the client communication unit management unit 35 is notified in step S17. To do.

  The client communication management unit 35 sends the alarm information notification from the target client in the received alarm information and intelligent information to the target client communication unit (for example, 31-2), thereby limiting the client system 51d and displaying the alarm information. Notification can be made. As a result, only the client system 51d shown in FIG. 10 is displayed that an alarm caused by path setting has occurred in the transmission apparatuses 53-1, 53-2.

  When a group ID is set in the intelligent information instead of the target client, the client communication management unit 35 refers to the target specified by the target client obtained by referring to the group database 41 with this group ID. Send alarm information notification to the communication section for clients.

  On the other hand, if the received alarm is an alarm that is not subject to notification limitation (normal alarm), the client information is registered in the alarm database 39 in step S16, and the client communication unit management unit 35 is notified in step S17.

  As a result, the client communication management unit 35 notifies the alarm information to all the client communication units 31-1 to 31-8. Therefore, alarms for which notification limited alarm information is not created in the intelligent database 40 are displayed on all client systems 51d, 51e, 51f as before.

  After that, when receiving a command transmission completion notification from the NE communication unit 33, the control unit 32 transmits a control completion notification to the client communication unit 31-2 requested to control, and the control process is completed.

<Third embodiment>
FIG. 12 shows a block diagram of an operation system for explaining the third embodiment of the present invention. In the figure, the same parts as those in FIG.

  FIG. 13 shows a flowchart for explaining the third embodiment of the present invention.

  When the server system 30 receives a control request having a diagnosis function from the client system 51d by the client communication unit (for example, 31-2), the server system 30 transmits a control execution request to the control unit 32 as having a diagnosis function. In step S21, the control unit 32 that has received the control execution request transmits a command transmission request to the NE communication unit 33 (step S22). At the same time, the knowledge database 42 and the configuration database 43 are referred to, an expected occurrence alarm for the control content is acquired, and notification limited alarm information is created in the intelligent database 40.

  For example, in the case of a control execution request for setting a path between the transmission apparatuses 53-1 to 53-6, the part HS-2-2 of the transmission apparatus 53-1 is determined from the contents of the knowledge database 42 and the configuration database 43. 1, part HS-2-2-1 of transmission device 53-2, part HS-2-2-1 of transmission device 53-3, part HS-2-2-1 of transmission device 53-4, transmission device 53 It is expected that an alarm (AU-LOP) will occur at the part HS-2-2-1 of the -5 part and the part HS-2-2-1 of the transmission apparatus 53-6, and one of the intelligent databases 40 shown in FIG. On the sixth line, records for the transmission apparatuses 53-1 (# 1) to 53-6 (# 6) are generated.

  As notification-restricted alarm information developed in the intelligent database 40, the control content is acquired from the control request from the client system, the setting client is acquired from the communication unit 31-2 for the client, the target client is the same as the setting client, and the diagnosis flag is ON. And Further, the notification limited alarm information developed in the intelligent database 40 is also developed in the diagnostic memory 38. The diagnosis reception flag of information developed in the diagnosis memory 38 is set to OFF.

  In step S23, the NE communication unit 33 notifies the intelligent alarm processing unit 34 when an alarm is received. When the intelligent alarm processing unit 34 receives an alarm from each transmission device, the intelligent alarm processing unit 34 refers to the intelligent database 40 using the above-mentioned alarm transmission device, generation site, and alarm type, and the received alarm is a notification limited process target (record presence / absence) ) Is determined (step S24).

  As a result, if the alarm is a notification limited target and the diagnostic function is ON (step S25), the diagnostic reception flag of the corresponding alarm information in the diagnostic memory 38 is changed to ON, and the notified alarm information is intelligently alarmed. The data is stored in the diagnostic processing buffer 34a in the unit 34 (step S26).

  On the other hand, if the received alarm is an alarm that is not subject to notification limitation (normal alarm), the client information is registered in the alarm database 39 in step S27, and the client communication unit management unit 35 is notified in step S29.

  If the alarm is a notification-limited target and the diagnosis function is OFF, intelligent information (intelligent database 40 record itself: alarm additional information) is added to the alarm information and registered in the alarm database 39 in step S28. In step S29, the client communication unit management unit 35 is notified.

  When receiving the command transmission completion notification from the NE communication unit 33 (step S30), the control unit 32 transmits the control completion notification to the client communication unit 31-2 requested to control, and at the same time, completes the process to the intelligent alarm processing unit 34. Send a notification. Further, the notification limited alarm information generated at the time of command transmission request to the NE communication unit 33 is deleted, and the control completion notification is notified to the client communication unit 31-2.

  When the intelligent alarm processing unit 34 receives the processing completion notification from the control unit 33 (step S31), the intelligent alarm processing unit 34 refers to the diagnostic reception flag of the corresponding information in the diagnostic memory 38. System address) is notified to the client communication management unit 35 (steps S32 and S29), and the alarm accumulated in the diagnostic processing buffer 34a is discarded.

  If all the diagnostic reception flags of the corresponding information in the diagnostic memory 38 are not ON, the diagnostic abnormality notification, the alarm information stored in the diagnostic processing buffer 32a, and the cause of the abnormality (information on the part where the diagnostic reception flag is OFF) are displayed. The client management unit 35 is notified together with the target client information (steps S32 and S29).

  The intelligent alarm processing unit 34 deletes the corresponding alarm information developed in the diagnostic memory 38 when the notification process is completed regardless of whether the diagnosis is normal or abnormal.

<Fourth embodiment>
FIG. 14 shows a functional block diagram of an embodiment of a client system. In the figure, a server communication unit 61 is connected to a server system to communicate with a server, and transmits a control request, receives an alarm notification, and the like.

  A GUI (Graphical User Interface) 62 includes a control request input unit 63a for inputting a control request, an additional input unit 63b for inputting an additional client, a notification limited input unit 63c for inputting a notification limited part, and a group setting input unit for setting a group. 63d, an output unit 64 for outputting an alarm, a cause, a list, or the like supplied from the server.

  When a target client (address) to which an alarm notification is added is input from the additional client input unit 63b of the GUI 62, the target client passes from the server communication unit 61 to the client communication unit (for example, 31-2) of the server system 30. The record of the target client that is received by the control unit 32 and added to the notification target input by the GUI 62 at the stage of generating the notification limited alarm information in the intelligent database 40 is also generated as the notification limited alarm information.

  When the intelligent alarm processing unit 34 receives the alarm information, the client information added to the client communication management unit (for example, 31-3) is notified by referring to the client record added as a notification target. It is possible to add a notification target.

  For example, when a test is performed using one or more specific transmission apparatuses, the test result may be displayed on a specific client system and may not be displayed on another client system.

  In such a case, a notification-restricted input unit 63c in the GUI 62 of a specific client system receives a notification-limited part (a specific transmission device, a specific physical position of the specific transmission device, or a specific path of a specific physical position of the specific transmission device, When the specific section is input, the notification limited part is received by the control unit 32 from the server communication unit 61 via the client communication unit (for example, 31-2) of the server system 30.

  Since the control unit 32 is a notification limiting process, the command generation process is not executed and information is created in the intelligent database 40. Thereby, as shown in the 3rd to 5th and 12th lines of the intelligent database 40 in FIG.

  Thereafter, the control unit 32 notifies the client communication unit 31-2 of a notification limiting process response and ends the process. When an alarm is generated, the intelligent processing unit 34 refers to the intelligent database 40, so that the alarm notification limiting process specifying the part can be performed.

  In addition, a notification limited state list can be designated when a notification limited part (specific transmission device) is input from the notification limited input unit 63c. The notification limited state list request is received by the control unit 32 from the server communication unit 61 via the client communication unit (for example, 31-2) of the server system 30.

  The control unit 32 extracts records whose control contents are NULL from the intelligent database 40, creates data for displaying a list of the extracted records, and responds to the requesting client system from the client communication unit 31-2. As a result, a list of specific transmission apparatuses for which notification limitation is set in the output unit 64 of the client system is displayed. FIG. 15 shows a state of the notification limited list. The contents of FIG. 15 are different from the contents of the intelligent database 40 shown in FIG.

  In this way, by displaying the notification-limited list, a specific transmission device to be tested can be confirmed in the client system.

  Further, when a group setting request is input from the group setting input unit 63d of the GUI 62, the group setting request is sent from the server communication unit 61 via the client communication unit (for example, 31-2) of the server system 30 to the group processing unit 36. Received at. As a result, the group processing unit 36 of the server system 30 creates client group information in the group database 41.

  Further, when the client communication unit (for example, 31-2) receives the group setting list request input from the group setting input unit 63d, the group processing unit 36 refers to the group database 41 with the group ID requested for the list. Thus, the group list display information is generated and transmitted from the client communication unit 31-2 to the requested client system, whereby the group list can be displayed in the requested client system.

  In addition, when a notification-limited alarm is received, the client communication management unit 35 refers to the group database 41 so that the display target client can be specified. For example, when an alarm occurs in the transmission apparatuses 53-1 and 53-2 due to path switching, if group ID = 1 is set in the notification limited alarm information of the corresponding group database 41, as shown in FIG. 16. The client systems 51a and 51b belonging to the group ID = 1 are notified of the alarm generated in the transmission apparatuses 53-1 and 53-2 and displayed on the GUI 62.

<Fifth embodiment>
FIG. 17 shows a flowchart for explaining the fifth embodiment of the present invention.

  When performing a notification limitation setting specifying a part from the notification limitation input unit 63c of the client system, if a timeout time (release time) as a notification limitation period is input, the control unit of the server system 30 that has received the request in step S41 When 32 creates notification limited alarm information in the intelligent database 40, it is possible to have a cancellation timer by giving the input notification limitation period as a timeout time. When the timeout time (release time) is not set, the control unit 32 automatically sets a time after a predetermined time from the current time as the timeout time (steps S42 and S43).

  In addition, the timer processing unit 37 of the server system 30 acquires the notification-limited alarm information that has timed out by referring to the timeout value of the intelligent database 40 at a constant time period (a relatively short period of several seconds to several minutes).

  When the timer processing unit 37 detects the notification limited alarm information (record) that has timed out in the intelligent database 40 (step S45), the timer processing unit 37 continues to the client communication management unit 35 with the detected notification limited alarm information setting client as a notification target. A notification of confirmation of cancellation is sent (step S46), and it is possible to display a confirmation screen for continuation / release of notification limitation on the setting client (step S48).

  When there is no set client, the absence processing notification from the client communication management unit 35 is accepted, and the timer processing unit 37 deletes the target notification limited alarm information (step S47). Also, even when there is no response from the setting client for a certain period of time, the timer processing unit 37 deletes the target notification limited alarm information (step S49).

  When the timer processing unit 37 receives the release request from the client communication units 31-1 to 31-8, the timer processing unit 37 deletes the target notification limited alarm information from the intelligent database 40, and when the continuation request is received, the timer processing unit 37 The time-out time of the target notification limited alarm information is updated from the intelligent database 40 based on the notification limited time limit input in step S50.

  In the above embodiment, the intelligent database 40 is used as an example of the storage unit, and the intelligent alarm processing unit 34, the client communication management unit 35, and the client communication units 31-1 to 31-8 are used as an example of the alarm notification unit. The control unit 32 is used as an example of a notification-limited alarm information generation unit, the intelligent alarm processing unit 34 is used as an example of a diagnosis unit, the control unit 32 is used as an example of a notification-limited list display information generation unit, and an example of a confirmation unit The timer processing unit 37 is used, the timer processing unit 37 is used as an example of an automatic release unit, the group processing unit 36 is used as an example of a grouping unit, and the group processing unit 36 is used as an example of a group list display information generation unit. .
