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 indicating a constant processing procedure for data indicating a network state collected from a communication network composed of various communication devices (hereinafter, rule). Is applied to process the data to monitor the state of the communication network, identify the location of the fault, etc., and to apply the data processing rule application method in the network management device.

[0002]

2. Description of the Related Art Conventionally, a network management device indicates the data collected from a communication network composed of various communication devices by the attribute of the data (such as which kind of communication device system the data was collected from). Information) was applied according to the rules determined according to the information. That is,
The attribute of the collected data was read, and a certain rule was applied to the data having the attribute to execute the processing.

For example, if the data a is the data having the attribute x, the rule f is applied to the data a to execute the processing, and if the data b is the data having the attribute y, the data b is processed. The process was executed by applying the rule g.

Further, when the rule to be applied cannot be uniquely determined according to the attribute of the data, it is classified according to the conditional expression and the processing is performed according to the conditional expression.

[0005]

In the above-mentioned conventional data processing rule application method, since the network management device processes the data by applying the rule determined for each attribute, the data collected for a certain period of time is processed. If it is necessary to process multiple groups depending on the network condition at the time of data generation, the rules will be applied randomly from any of the applicable rules. However, there is a problem that the expected true processing result may not be obtained.

For example, when one data a is generated and another data b is additionally generated (however, the content of only data b is the same as when it is generated independently), the data a The expected true processing result was not obtained even if the processing of only the data b generated accompanying the above processing was performed without considering the above.

In view of the above points, an object of the present invention is to provide a priority of application in consideration of a combination of attributes of data between rules to be applied, and select and apply a rule having a high priority first. The purpose of the present invention is to provide a data processing rule application method capable of performing appropriate processing on a data group.

[0008]

The data processing rule application method of the present invention applies a rule representing a certain processing procedure to data indicating a network state collected from a communication network composed of various communication devices.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a network management device 1 to which a data processing rule application system according to an embodiment of the present invention is applied.
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,
The data processing means 4, the rule selection means 5, the data buffer 6, the processing result output means 7, and the analysis control means 8 are included.

Referring to FIG. 2, the rule storage unit 3 stores a plurality of entries in a table format, each of which is composed of a combination of data attributes, rules to be applied, priority of application, and a next processing continuation flag. In FIG. 2, for example, the rule group h including the rules f and g may be applied to the data group c including the data a having the attribute x and the data b having the attribute y. The priorities 1 and 2 of the rules f and g to be applied in consideration of the combination (x, y) of the data b with the attribute y are defined. Further, unless it is obvious that the generation of the data b is an incidental phenomenon caused by the generation of the data a and it is not necessary to process the data b of the data group c, the next processing continuation flag is set in correspondence with the priority 1. Therefore, the next processing continuation flag is set not to be set in correspondence with the priority 2.

Referring to FIG. 3, the processing of the data processing rule application method of this embodiment is performed by a data group collecting step 101.
A data group analysis step 102, a rule group reading step 103, and a high priority rule selection step 104
And 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 system of this embodiment having the above-mentioned configuration will be described.

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

The analysis control means 8 is activated at regular time intervals, analyzes the data group c accumulated in the data buffer 6, and analyzes the attribute x of each data a and b which compose the data group c.
And obtain a combination (x, y) of y (step 10).
2). Further, the analysis control means 8 gives an instruction to the data processing means 4 to transfer the data group c of the data buffer 6 to the data processing means 4.

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

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

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

Next, the data processing means 4 refers to the next processing continuation flag stored corresponding to the applied rule f and judges whether or not to continue the next processing (step 106). Since the next processing continuation flag is now 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 the rule g is applied to the data group c in step 105 to execute the process. In step 106, the next process 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).

By the way, in the description of the operation of the above embodiment,
Although the case where the collected data group c is composed of the data a and b has been described as an example, the present invention is similarly applicable even when the collected data group c is composed of one or three or more data. Needless to say. Note that the causal relationship (correlation) may be determined by referring to a network configuration database or the like between the collected data of the data group, and the present invention may be applied to a plurality of data having a causal relationship as the data group. ..

According to the data processing rule application method of this embodiment, particularly in a network management device for identifying a failure point based on alarm data from a communication network,
When the fault condition data obtained in the system of a certain type of communication device (eg, optical communication device) is exactly the same as the state due to the fault of another type of communication device (eg, wireless communication device), but its meanings are different , By first clarifying this cause by a rule that considers the fault condition of another type of communication device, and then applying the rule to the fault state data from the grid of a certain type of communication device, correct the network state. You can judge.
