DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing rule application method, and more particularly, to a rule representing a certain processing procedure for data indicating a network state collected from a communication network composed of various communication devices (hereinafter referred to as a rule). The present invention relates to a data processing rule application method in a network management device that performs data processing by applying the above-mentioned method and monitors the state of a communication network, specifies a failure point, and the like.

[0002]

2. Description of the Related Art Conventionally, a network management device uses data collected from a communication network composed of various communication devices to indicate the attribute of the data (for example, the type of communication device from which the data is collected). Information), and the processing was executed by applying rules determined according to the information. That is,
The attribute of the collected data is read, and the data having the attribute is processed by applying a certain rule.

For example, if data a is data of attribute x, a process is executed by applying rule f to data a, and if data b is data of attribute y, The processing has been executed by applying the rule g.

When a rule to be applied is not uniquely determined according to the attribute of data, a case is divided by a conditional expression, and processing is performed in accordance with the conditional expression.

[0005]

In the above-described conventional data processing rule application method, the network management device processes data by applying a rule determined for each attribute. If a group needs to be processed across multiple rules depending on the network state at the time of data generation, it will be applied randomly from any of the applicable rules. However, there is a problem that an expected true processing result may not be obtained.

For example, when a certain data a occurs and another data b accompanies it (however, it is assumed that only the data b has the same content as a case where it occurs alone). However, the expected true processing result could not be obtained even if the processing of only the accompanying data b was performed first without considering the above.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a priority of application in consideration of a combination of data attributes between rules to be applied, and select and apply a rule having a higher priority first. Another object of the present invention is to provide a data processing rule application method that enables appropriate processing to be performed on a data group.

[0008]

According to the data processing rule application method of the present invention, a rule representing a predetermined processing procedure is applied to data indicating a network state collected from a communication network composed of various communication devices. A network management device that performs data processing by using a rule storage unit that stores a rule applied to data in accordance with a combination of data attributes and a priority of application among a plurality of rules; A rule selecting means for reading out a rule group corresponding to a combination of data attributes constituting from the rule storing means, and applying the rule group read by the rule selecting means to the collected data group in order of priority. And data processing means for executing the processing.

[0009]

According to the data processing rule application method of the present invention, the rule storage means stores rules applied to data in accordance with combinations of data attributes and application priorities among a plurality of rules. Read from the rule storage means a rule group corresponding to a combination of data attributes constituting the collected data group, and the data processing means gives priority to the collected data group to the rule group read by the rule selecting means. Apply the process in order and execute the process.

[0010]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a network management apparatus 1 to which a data processing rule application method according to an embodiment of the present invention is applied.
FIG. 3 is a block diagram showing the configuration of FIG. The network management device 1 includes a data collection unit 2, a rule storage unit 3,
It comprises a data processing means 4, a rule selection means 5, a data buffer 6, a processing result output means 7, and an analysis control means 8.

Referring to FIG. 2, the rule storage means 3 stores a plurality of entries including combinations of data attributes, applied rules, application priorities, and next processing continuation flags in a table format. In FIG. 2, for example, it is conceivable to apply a rule group h composed of rules f and g to a data group c composed of data a of attribute x and data b of attribute y. Priority 1 and 2 of rules f and g to be applied in consideration of the combination (x, y) with attribute y of data b are determined. Unless it is clear that the occurrence of data b is an incidental phenomenon due to the occurrence of data a and it is not necessary to perform processing on data b of data group c, the next processing continuation flag is set in correspondence with the priority level 1. Therefore, the setting is made so that the next processing continuation flag is not set in accordance with the priority 2.

Referring to FIG. 3, the processing of the data processing rule application method according to the present embodiment is performed by a data group collecting step 101.
, Data group analysis step 102, rule group read step 103, high priority rule selection step 104
, A rule application processing execution step 105, a next processing continuation determination step 106, and a processing result output step 107.

Next, the operation of the data processing rule application method of the present embodiment configured as described above will be described.

In the network management device 1, the data collection means 2 randomly collects various data indicating the network status from a communication network composed of various communication devices and sequentially accumulates them in the data buffer 6 (step 101). Here, it is assumed that, for example, a data group c including data a of the attribute x and data b of the attribute y is collected and stored in the data buffer 6.

The analysis control means 8 is activated at regular intervals, analyzes the data group c stored in the data buffer 6, and analyzes the attribute x of each of the data a and b constituting the data group c.
Acquire a combination (x, y) of and y (step 10)
2). Further, the analysis control unit 8 gives an instruction to the data processing unit 4 to cause the data group c in the data buffer 6 to be transferred to the data processing unit 4.

The data processing means 4 includes attributes x and y of each of the data a and b constituting the transferred data group c.
The rule group h including the rules f and g is read from the rule storage means 3 in accordance with the combination (x, y) (step 103), and the rule selection means 5 is called.

The rule selecting means 5 assigns a rule f having the highest priority to a combination (x, y) of the attributes x and y of the data a and b to the data a and b constituting the data group c. The data is selected from the group h and notified to the data processing means 4 (step 104).

The data processing means 4 transmits the notified rule f
Is applied to the data group c to execute the processing (step 10
5). Note that the rule f has a function of selecting the data a of the attribute x applied to itself, and does not perform the processing on the data b of the attribute y to which the rule g is to be applied.

Subsequently, the data processing means 4 determines whether or not to continue the next processing by referring to the next processing continuation flag stored corresponding to the applied rule f (step 106). Now, the next processing continuation flag is set,
The data processing means 4 returns the control to step 104 to execute the next processing.

In step 104, the rule g having the next highest priority is selected from the rule group h, and in step 105, the rule g is applied to the data group c and the processing is executed. Since the continuation flag is not set, the data processing means 4 outputs the processing result to the processing result output means 7 (step 107).

In the description of the operation of the above embodiment,
Although the case where the collected data group c is composed of data a and b has been described as an example, the present invention can be similarly applied to a case where the collected data group is composed of one or more data. Needless to say. A causal relationship (correlation) may be determined between data of the collected data group with reference to a network configuration database or the like, and the present invention may be applied to a plurality of data having a causal relationship as a data group. .

According to the data processing rule application method of the present embodiment, in a network management apparatus for specifying a fault location based on alarm data from a communication network,
When the fault status data obtained in the system of a certain type of communication device (for example, an optical communication device) is exactly the same as the status due to a failure of another type of communication device (for example, a wireless communication device), but the meaning is different. First, the cause is clarified by a rule that considers the fault condition of another type of communication device, and then the rule is applied to fault status data from the system of a certain type of communication device, so that the network status can be correctly corrected. You can judge.
