  Conventionally, in order to provide an appropriate communication service using a communication network, as a process for maintenance management in addition to a normal communication process, it is possible to perform periodic processing such as quality measurement of devices constituting the network and the operation of a maintenance person. Event processing such as command processing for input data setting and status monitoring is performed using network communication.

  Maintenance management processing such as periodic processing / event processing is executed regardless of the system load status when a processing request is generated.

  As a result, there is a risk that the load increases due to the execution of the periodic processing / event processing, quality degradation such as delay occurs, or regulation is performed because it is judged as a congestion state.

  As a technique for controlling communication traffic congestion in a network, there is a system described in Patent Document 1 or Patent Document 2.

  In the traffic congestion control system described in Patent Document 1, it is possible to efficiently perform communication control by performing congestion control for each user and reducing a wasteful processing amount for congestion control.

  Further, in the communication system described in Patent Document 2, when the system falls into an overload state, the response of the call setting signal and the data transfer signal is delayed within a range specified by the protocol to alleviate the load state. As a result, it is possible to restore the communication system to a normal state without substantially impairing communication and connectivity in the communication service and without excessively reducing the processing amount of the communication system.

<Configuration of Maintenance Management Device According to One Embodiment>
The configuration of the maintenance management device 1 according to an embodiment of the present invention will be described with reference to FIG.

  The maintenance management device 1 according to the present embodiment is connected to a maintenance terminal 2 to be maintained, and includes a load data management unit 11, a process increase load data calculation unit 12, a process increase load data storage unit 13, and a process execution control data storage unit. 14, a command execution control unit 15, a skip number management unit 16, and an escalation function unit 17.

  The load data management unit 11 includes, as load data of the self-maintenance management apparatus 1, a load data acquisition unit 11a that acquires a CPU usage rate, a memory usage rate, a load status of the disk IO, and the like at predetermined time intervals, and this load data acquisition unit And a load data storage unit 11b for storing the load data acquired in 11a.

  When a command related to maintenance of the maintenance terminal 2 is executed, the process increasing load data calculating unit 12 calculates the amount of change in load data due to the execution of the command as process increasing load data.

  The process increasing load data storage unit 13 stores the process increasing load data calculated by the process increasing load data calculation unit 12 together with the identification information of the corresponding command.

  The process execution control data storage unit 14 stores, as process execution control data, a function for determining a threshold value used in the command execution control unit 15 for controlling execution of the command.

  When the command execution control unit 15 obtains a command for maintenance of the maintenance terminal 2 or an execution request for periodic processing, the load data stored in the load data storage unit 11b of the load data management unit 11 and the processing increase load data storage Based on the process increasing load data stored in the unit 13 and the threshold calculated from the process execution control data stored in the process execution control data storage unit 14, it is determined whether or not the requested command can be executed. When it is determined that the command can be executed, the command is executed. When it is determined that the command cannot be executed, the command is not executed and the command is skipped.

  The skip number management unit 16 counts, for each command, the number of times that the command execution control unit 15 has skipped execution of the command for the periodic process.

  The escalation function unit 17 is configured to increase the threshold value for controlling the execution of the command with respect to the command for the periodic process in which the skip count counted by the skip number management unit 16 exceeds a preset threshold value. The function stored in the storage unit 14 is updated.

<Operation of Maintenance Management Device According to One Embodiment>
Next, as an operation of the maintenance management device according to the present embodiment, a process when an execution request for “command A” is transmitted from the maintenance terminal 2 will be described with reference to FIGS.

  In the present embodiment, the process execution control data storage unit 14 stores process execution control data that is a function for determining a threshold value used for command execution control in the command execution control unit 15.

  An example of the process execution control data is shown in FIG. In the process execution control data of FIG. 2, when the current (latest) load data is “0 (%) to 40 (%)”, the determination threshold value for controlling the execution of the command is set to “80 (%)”. When the current (latest) load data is “40 (%) to 70 (%)”, the determination threshold value for controlling execution of the command is set to “90 (%)”, and the current (latest) load data Is “70 (%) to 90 (%)”, the determination threshold value for controlling the execution of the command is set to “95 (%)”, and the current (latest) load data is “90 (%) to 100 (%)”. "(%)" Indicates that the command cannot be executed. Command execution control using this threshold will be described later.

  Further, the process increasing load data storage unit 13 stores process increasing load data, which is an increase amount of the load data by executing each command (including the command A), which is calculated every time the command is executed during the past event processing. ing.

  An example of the processing increase load data is shown in FIG. In the process increase load data of FIG. 3, the process increase load data of the command A is “15 (%)”, the process increase load data of the command B is “2 (%)”, and the process increase load of the periodic process C The data is “7 (%)”, and the process increasing load data of the periodic process D is “5 (%)”. The process of calculating the process increasing load data will be described later.

  The operation of the maintenance management apparatus 1 when the maintenance management apparatus 1 operates in a state where these pieces of information are stored will be described with reference to the flowchart of FIG.

  As the present embodiment, a case will be described in which processing is executed using the processing execution control data in FIG. 2, the processing increase load data in FIG. 3, and the CPU usage rate as load data.

  First, when the maintenance management device 1 is operated, the load data acquisition unit 11a of the load data management unit 11 starts acquiring the CPU usage rate as load data of the own maintenance management device 1 at a predetermined time interval. It is stored in the storage unit 11b (S1).

  Next, when an execution request for the command A is transmitted from the maintenance terminal 2 to be maintained and received by the maintenance management device 1 (“YES” in S2), the command execution control unit 15 executes the load data management unit 11 The load data stored in the load data storage unit 11b, the process increase load data stored in the process increase load data storage unit 13, and the threshold value calculated from the process execution control data stored in the process execution control data storage unit 14 Based on the above, it is determined whether or not the requested command A can be executed (S3).

  A process for determining whether or not to execute the command A, which is executed in the command execution control unit 15, will be described with reference to the flowchart of FIG.

  First, the load data storage unit 11b of the load data management unit 11 is referred to, and the load data “53 (%) of the time (t1)“ 1:29:20 ”shown in FIG. ) "Is extracted (S31).

  Next, the process increasing load data in FIG. 3 stored in the process increasing load data storage unit 13 is referred to, and the process increasing load data Y “15 (%)” for the command A is extracted (S32).

  Next, a command requested from the current (latest) load data X “53 (%)” extracted in step S31 and the process execution control data of FIG. 2 stored in the process execution control data storage unit 14 is requested. A determination threshold “90 (%)” for determining whether or not A can be executed is calculated (S33).

  Next, the sum of the current (latest) load data X “53 (%)” extracted in step S31 and the processing increase load data Y “15 (%)” for the command A extracted in step S32 is the command. Calculated as predicted load data when A is executed (S34), and if this predicted load data is smaller than the determination threshold “90 (%)” calculated in step S33 (“YES” in S35), the command A It is determined that the execution is possible (S36), and if it is larger (“NO” in S35), it is determined that the execution is impossible (S37). Here, since the sum “68 (%)” of the current (latest) load data “53 (%)” and the processing increased load data “15 (%)” is smaller than the threshold value “90 (%)”, the command It is determined that A can be executed.

  Returning to the flowchart of FIG. 4, if it is determined that the requested command A can be executed (“YES” in S4), the command A is executed by the command execution control unit 15 and an execution request for the command A is issued. The transmission maintenance terminal 2 is notified that the command A has been executed (S5). This notification is notified to the administrator by display on the maintenance terminal 2 or the like.

  When the command A is executed by the command execution control unit 15, the process increasing load data relating to the command A is calculated by the process increasing load data calculating unit 12 (S6).

  The process of calculating the process increasing load data in the process increasing load data calculating unit 12 will be described with reference to the flowchart of FIG. In this embodiment, as load data (CPU usage rate), as shown in FIG. 6, immediately before the start of execution of command A (t1) = “53%”, immediately after the start of execution of command A (t2) = “71% ”, Command A executing (t3) =“ 72% ”, executing (t4) =“ 71% ”, immediately before the completion of command A execution (t5) =“ 70% ”, immediately after the completion of command A execution (t6) ) = “54%” is sequentially acquired by the load data acquisition unit 11a of the load data management unit 11 and stored in the load data storage unit 11b.

  When execution of the command A is started, the command name (here, command A) and execution start time information are sent from the command execution control unit 15 to the process increasing load data calculation unit 12 (S61).

  When the process start load data calculation unit 12 acquires the execution start time information of the command A, the load data “53 (%)” immediately before the start of execution (t1) and the load data “71” immediately after the start of execution (t1) are obtained. (%) ”Is acquired from the load data storage unit 11b of the load data management unit 11, and an increase change amount“ 71 (%) − 53 (%) = 18 (%) ”due to the start of execution of the command A is calculated. (S62).

  When the execution of the command A is terminated, the command name (here, command A) and the execution end time information are sent from the command execution control unit 15 to the process increasing load data calculation unit 12 (S63).

  When the processing increase load data calculation unit 12 acquires the execution end time information of the command A, the load data “70 (%)” immediately before the end of execution (t5) and the load data “54” immediately after the end of execution (t6) are obtained. (%) ”Is acquired from the load data storage unit 11b of the load data management unit 11, and the downward change amount“ 70 (%) − 54 (%) = 16 (%) ”by the completion of the execution of the command A is calculated. (S64).

  Next, the process increasing load data calculation unit 12 averages “18 (%) / 2 + 16 (%) / 2 = 17 (%)” of the increasing change amount due to the start of execution of this command A and the decreasing change amount due to the end of execution. Is calculated as new process increasing load data of the command A (S65).

  Returning to the flowchart of FIG. 4, the process increase load data of the command A in the process increase load data storage unit 13 is changed from “15 (%)” to “17 (17) by the new process increase load data calculated in step S65. %) ”(S7).

  In this way, the process increasing load data in the process increasing load data storage unit 13 is updated to the latest data every time a new command is executed.

  As the calculation method of the process rising load data, as described above, in addition to the method using the average value of the rising change amount at the start of the command execution and the falling change amount at the end of the execution, the past rising change amount and the falling change amount are calculated. A method using the weighted average value used may be used. Further, as a method of calculating the rising (falling) load amount, a method using a difference between the average value of the load data before execution and the average value or intermediate value of the load data being executed may be used.

  When it is determined in step S4 that the requested command A cannot be executed (“NO” in S4), the command A is skipped and the command A is sent to the maintenance terminal 2 that has transmitted the request for execution of command A. On the other hand, it is notified that the command A has been skipped (S8). This notification is notified to the administrator by display on the maintenance terminal 2 or the like.

  Here, when the skip-processed command is due to the regular process (“YES” in S9), the skip number management unit 16 counts the number of skip processes for the command (S10).

  If the counted number of skip processes becomes higher than a preset threshold value (“YES” in S11), the escalation function unit 17 increases the process execution control data threshold value for the corresponding command. (S12). By being controlled in this way, it is possible to avoid a situation in which the periodic process is not executed and a situation where skipping frequently occurs.

  In addition, since the maintenance management device 1 is equipped with a forced execution function based on an operator's judgment, the command execution control unit 15 executes commands for event processing such as command processing input as forced execution processing by the operator. The situation where event processing is not executed may be avoided by forcibly executing skipping / non-permission determination processing.

  According to the present embodiment described above, it is possible to appropriately control the load state by predicting the load data at the time of command execution and determining whether or not the command can be executed. It is possible to avoid the deterioration of communication service quality such as delay due to delays, and the occurrence of call inflow restriction (measures for making outgoing call restriction or inflow call loss) due to congestion control.

  In addition, by setting the threshold value (processing execution control data) for determining whether to execute the command as a function that is variable according to the current (latest) load data status instead of a constant, the current load status It is possible to make an appropriate determination according to the situation and to perform flexible operation.

  Further, by installing an escalation function or a forced execution function based on the operator's judgment, it is possible to control so that the periodic process or the event process is not permanently skipped.

  In addition, since the process increasing load data stored in the process increasing load data storage unit is updated in real time based on the actual measurement value, it is necessary to set the data for each hardware performance without departing from the actual value. There is an effect that there is no.

  In the above-described embodiment, the case where the CPU usage rate is used as the load data has been described. However, the memory usage rate, the load on the disk IO, the number of command executions, the number of calls, and the like may be used.

  In the above-described embodiment, the process execution control data is a function using the current load data, but may be a function using the current load data set for each time zone.

  Moreover, it is also possible to construct a maintenance management program for causing the computer to function as a maintenance management apparatus by programming the functions of the maintenance management apparatus according to the present embodiment into a computer.
