[Quality index processing system]
Referring to FIG. 1 showing a system configuration in an embodiment, a quality index processing system 1 includes an aggregation device 2, a plurality of monitoring devices (# 1 to # 3) 3, a plurality of network transmission signal branching / extracting devices (# 1 to # 3) TAP, a plurality of business servers (# 1, # 2) 4, a plurality of client devices (# 1 to # 6) 5, a core network 6, a plurality of user networks (# 1 to # 3) 7, And a maintenance network 8.

  The aggregation device 2 as the upper (center) collector is periodically transferred from each of the plurality of monitoring devices (# 1 to # 3) 3 operating in time synchronization (for example, at intervals of 1 minute). The calculation results are aggregated, that is, aggregated and statistically processed.

  Each monitoring device 3 serving as a probe that is distributedly arranged corresponding to each monitoring location for quality index calculation is operated through a network line to be monitored via a corresponding network transmission signal branching / extracting device TAP. After the transmission data in the packet form is captured as a network transmission signal (sometimes simply referred to as a packet), packet analysis is performed and a quality index is calculated. For example, the number of monitoring devices 3 that are distributed and arranged corresponding to each monitoring location is several hundred to several thousand.

A network transmission signal branching / extracting device (sometimes simply referred to as a tap) TAP is inserted and connected to a monitored network line between the core network 6 and the user network 7 and replicates a packet as a network transmission signal. Branch and take out, that is, mirror.

The core network 6 includes a plurality of IP (Internet Protocol) routers such as edge routers as network devices (not shown), and accommodates a plurality of business servers (# 1, # 2) 4. Each user network 7 includes network devices (not shown) such as an L2 (layer 2) switch and an L3 (layer 3) switch, and accommodates a plurality of client devices 5, respectively. The maintenance network 8 connects the aggregation device 2 and a plurality of monitoring devices (# 1 to # 3) 3.

In this quality index processing system 1, KPI (Key Process Indicator) is used as a quality index. KPI is an index for process monitoring and measurement, and is sometimes called a process evaluation index. There are several tens of quality index (KPI) items in the monitored network line. KPI (A): number of packets, KPI (B): traffic volume, and KPI (C): number of lost packets, etc. .

  In addition, in order to transfer the quality index (KPI) calculation result calculated by each monitoring device 3 to the aggregation device 2, a KPI result file in which the calculation results of a plurality of KPI items are collected is used.

  In brief, in the quality index processing system 1, a plurality of client devices (# 1 to # 6) 5 respectively accommodated in a plurality of user networks (# 1 to # 3) 7 start communication. Communication from each client device 5 takes a form of accessing any one of a plurality of business servers (# 1, # 2) 4 through the user network 7 and the core network 6 according to the business purpose.

  Each monitoring device 3 distributed in correspondence with each monitoring location captures operational packets transmitted and received between the client device 5 and the business server 4 via the corresponding tap TAP, and then performs packet analysis The KPI is calculated. The calculated KPI result (KPI calculation result) is periodically (specifically) as a KPI result file from each monitoring device 3 to the aggregation device (sometimes simply referred to as a collector) 2 via the maintenance network 8. Is transferred once per minute).

  The collector 2 performs aggregation processing after receiving the KPI result file from each monitoring device 3. The collector 2 stores the result of the aggregation processing internally using RAM and ROM, but may store it in an external recording device (not shown) as a database.

  Further, the collector 2 determines whether the KPI item for each monitoring device 3 is important or not based on the content (KPI value) of the KPI result file received from each monitoring device 3. The KPI item that is determined to be important is a KPI value that has a large influence on the sum or average of all the monitoring apparatuses 3 and is a transfer target from the monitoring apparatus 3 to the collector 2. In addition, the KPI item determined to be unimportant is a KPI value that has a small influence on the sum or average in all the monitoring devices 3 and is not a transfer target from the monitoring device 3 to the collector 2. Then, the collector 2 notifies each monitoring device 3 of this important / unimportant determination result as instruction notification information (transfer permission condition), and each monitoring device 3 calculates KPI to the collector 2 only when the transfer permission condition is satisfied. Transfer the result.

  For example, KPI items included in the KPI result file transferred from the monitoring device (# 1) 3 to the collector 2, that is, KPI (A), KPI (B), and KPI (C) are at least 1 in the collector 2. When important determination is made before the cycle, all corresponding KPI values (100, 300, and 50) are to be transferred.

  Also, only KPI items included in the KPI result file transferred from the monitoring device (# 2) 3 to the collector 2, that is, KPI (B) of KPI (A), KPI (B), and KPI (C). However, if the collector 2 makes an important decision at least one cycle before, the corresponding KPI value (300 million) is to be transferred. That is, the KPI values (1 and 0) corresponding to the KPI (A) and KPI (C) determined as unimportant are not transferred.

(Monitoring device)
As shown in FIG. 2, the monitoring device 3 that is distributed and arranged corresponding to each monitoring location includes the following elements as a hardware configuration. That is, a CPU (Central Processing Unit) as a processor, a RAM (Random Access Memory) as a working memory, a ROM (Read Only Memory) storing a boot program for startup, an OS (Operating System), A disk as a nonvolatile flash memory that stores various application programs and various information (including data) in a rewritable manner, a NIC (Network Interface Card) as a communication interface, and the like. Since these hardware configurations can be easily understood and implemented by those skilled in the art, illustration of this configuration is omitted here.

  In order to logically realize the quality index calculation processing function to be described in detail later, in the monitoring device 3, a control program (quality index calculation control program) is installed on the disk as an application program. In this monitoring device 3, the CPU always develops this control program in the RAM and executes it as a resident program.

  More specifically, the monitoring device 3 includes network interfaces (NET / IF) 30, 31, and 32 that can be realized by a NIC. The monitoring device 3 includes a packet capture processing unit 33, a collection information analysis unit 34, an instruction notification information determination unit 35, a collection information transfer unit 36, an instruction notification information reception unit 37, a reception result storage processing unit 38, and instruction notification information. A storage unit 39 is provided as a functional component.

  In the monitoring device 3, the packet capture processing unit 33 that operates as a capture engine captures a packet from the tap TAP via the NET / IF 30. The captured packet is analyzed by the collection information analysis unit 34, and KPI as a quality index is calculated.

  The instruction notification information determination unit 35 determines (determines) whether to transfer the KPI calculation result to the collector 2 based on the instruction notification information as the transfer permission condition stored in the instruction notification information storage unit 39 in the table form. When there is a KPI calculation result to be transmitted to the collector 2, the KPI calculation result is transferred to the collector 2 as a KPI result file via the collection information transfer unit 36 and the NET / IF 31.

  In the monitoring device 3, the instruction notification information receiving unit 37 receives instruction notification information from the higher-order collector 2 via the NET / IF 32. The received instruction notification information is stored in the instruction notification information storage unit 39 by the reception result storage processing unit 38.

  Here, the instruction notification information as the transfer permission condition stored in the instruction notification information storage unit 39 (may be described as an instruction notification information table) 39 will be described with reference to FIG. The instruction notification information includes a KPI item and a transfer order (number of digits of value) for each KPI item.

  Examples of KPI items include KPI (A): number of packets, KPI (B): traffic volume, and KPI (C): number of lost packets. The corresponding transfer orders include one million, one million, and one. Illustrated.

  Since the order indicates the number of digits of the value, for example, when the value is 1.2 million, the order is 1 million. Therefore, the transfer order indicates the minimum numerical value for executing the transfer of the KPI item. For example, as shown in FIG. 4, when the transfer order of KPI (A): number of packets of KPI item is 1 million, transfer to collector 2 when KPI (A) is greater than 1 million. It becomes a target.

(Aggregator)
As shown in FIG. 3, the collector 2 as a higher-level aggregation device includes the following elements as a hardware configuration. That is, a CPU as a processor, a RAM as a working memory, a ROM storing a boot program for startup, and a non-volatile storage that rewrites the OS, various application programs, and various information (including data). A disk as a flash memory and a NIC as a communication interface. Since these hardware configurations can be easily understood and implemented by those skilled in the art, illustration of this configuration is omitted here.

  In order to logically realize the quality index aggregation processing function of the quality index (KPI) calculation result to be described in detail later, in the collector 2, a control program (quality index aggregation control program) is installed on the disk as an application program. In the collector 2, the CPU always develops this control program in the RAM and executes it as a resident program.

  More specifically, the collector 2 includes network interfaces (NET / IF) 20 and 21 that can be realized by a NIC. Further, the collector 2 includes a KPI result file acquisition control unit 22, a KPI result file information analysis unit 23, a KPI aggregation unit 24, a KPI aggregation result storage processing unit 25, a KPI aggregation result information storage unit 26A, and an instruction condition setting information storage unit 26B. The instruction notification information storage unit 26C, the instruction notification information receiving unit 28, and the instruction notification processing unit 29 are provided as functional components.

  In the collector 2, the KPI result file acquisition control unit 22 receives the KPI result file from each monitoring device 3 periodically (specifically, once per minute) via the NET / IF 20. The KPI result file acquisition control unit 22 has a buffer (FIFO (First in First Out) queue) for storing the KPI result file received from each monitoring device 3 for each monitoring device 3 as a transmission source.

  The KPI result file information analysis unit 23 reads the content (KPI value) of the KPI result file received from each monitoring device 3 from the corresponding buffer in the KPI result file acquisition control unit 22 and notifies the KPI aggregation unit 24 of it. In addition, the KPI result file information analysis unit 23 reads information of the KPI aggregation result information storage unit 26A that stores the results aggregated at least one cycle before and the instruction condition setting information storage unit 26B.

  The KPI result file information analysis unit 23 stores the KPI order in the corresponding KPI item stored in the KPI aggregation result information storage unit 26A as the KPI aggregation result information at least one cycle before, and the instruction condition setting information as instruction condition setting information. A multiplication value with the transfer order ratio (condition setting value) in the corresponding KPI item stored in the section 26B is obtained. Then, the KPI result file information analysis unit 23 determines whether the multiplication value (new order information) is different from the value of the transfer order (old order information) stored in the instruction condition setting information storage unit 26B.

If they are different, the KPI result file information analysis unit 23 saves the instruction notification information storage unit 26 </ b> C as content to be instructed to each monitoring device 3, and the instruction condition setting information storage unit 2.
The information on the transfer order of 6B is updated to new order information.

  The KPI result file information analyzing unit 23 calls the processing of the instruction notification information receiving unit 28 and the instruction notification processing unit 29 when there is content (instruction notification information) to be instructed to each monitoring device 3, and the NET / IF 21. To each monitoring device 3.

  Subsequent to the processing described above in the KPI result file information analysis unit 23, KPI aggregation processing is performed. The KPI aggregation unit 24 performs aggregation, that is, aggregation and statistics on the newly received KPI calculation result, and calls the KPI aggregation result storage processing unit 25. The KPI aggregation result storage processing unit 25 stores the KPI aggregation result as KPI aggregation result information in the KPI aggregation result information storage unit 26A.

  Here, the instruction condition setting information stored in the instruction condition setting information storage unit 26B (also referred to as an instruction condition setting information table) 26B in the form of a table will be described with reference to FIG. The instruction condition setting information includes a KPI item, a KPI order (number of value digits) for each KPI item, a transfer order ratio (%) for each KPI item, and a transfer order (number of value digits) for each KPI item. Including.

  The KPI items include KPI (A): number of packets, KPI (B): traffic volume, and KPI (C): number of lost packets. The KPI order is a KPI value calculated in the collector 2 currently stored as KPI aggregation result information in the KPI aggregation result information storage unit 26A of the collector 2 (at least one cycle before). The transfer order ratio is a ratio for determining an order for transfer, and is a predetermined condition setting value. The transfer order is instruction notification information to be transferred to the monitoring device 3. The order indicates the number of digits of the value.

  The transfer order ratio is a ratio indicating what percentage of the order of the KPI calculation result stored in the collector 2 as KPI aggregation result information is to be transferred. For example, in the example of FIG. 5, the KPI item KPI (A): the number of packets has a KPI result on the order of 100 million, but 1% of this is 1 million (= 100 million × 1%). ) As a transfer order. In this case, the monitoring device 3 becomes a transfer target to the collector 2 only when a value larger than 1 million is calculated as KPI.

  Next, the instruction notification information broadcast from the collector 2 to each monitoring device 3 will be described with reference to FIG. The instruction notification information stored in the instruction notification information storage unit (instruction notification information table) 26C includes a collector IP address, a KPI item, and a transfer order (number of digits of value) for each KPI item.

  The KPI item includes KPI (A): number of packets, KPI (B): traffic volume, and KPI (C): number of lost packets, and the corresponding transfer order matches the transfer order of the instruction condition setting information. One million, one and one.

  This transfer order is important / non-important determination result information determined from the result calculated by the KPI result file information analysis unit 23 based on the contents of the instruction condition setting information and transmitted to each monitoring device 3.

[Quality index calculation processing]
Next, an example of quality index (KPI) calculation processing in the quality index processing system 1 according to one embodiment will be described with reference to FIGS. 1, 2, and 3 and related drawings. FIG. 7 shows a flow of quality index calculation processing in the monitoring device 3.

  As outlined, in the quality index processing system 1, a plurality of client devices (# 1 to # 6) 5 respectively accommodated in a plurality of user networks (# 1 to # 3) 7 start communication. Communication from each client device 5 takes a form of accessing any one of a plurality of business servers (# 1, # 2) 4 through the user network 7 and the core network 6 according to the business purpose.

  Each monitoring device 3 distributed in correspondence with each monitoring location captures operational packets transmitted and received between the client device 5 and the business server 4 via the corresponding tap TAP, and then performs packet analysis Then, the KPI as the quality index is calculated. The calculated KPI result (KPI calculation result) is periodically (specifically, once per minute) as a KPI result file from each monitoring device 3 to the collector 2 via the maintenance network 8. .

  More specifically, in the quality index processing system 1, the packet capture processing unit 33 of each monitoring device 3 branches out and extracts an operational packet (IP packet) from the monitored network line corresponding to the monitored location in a replicated state. The packet taken out by the tap TAP is received (captured) via the NET / IF 30 (S71 in FIG. 7).

  The collection information analysis unit 34 analyzes the received packet as collection information and calculates a KPI as a quality index (S72). The KPI items calculated here are KPI (A): number of packets / min, KPI (B): traffic volume / min, KPI (C): number of lost packets / min, and the like for each monitored network line. is there.

  The instruction notification information determination unit 35 determines whether information of the same KPI item as the calculated corresponding KPI result exists in the instruction notification information table 39 (see FIG. 4) (S73).

  When the determination in step S73 is affirmative, the instruction notification information determination unit 35 compares the order (transfer order) for transfer existing in the instruction notification information table 39 with the calculated KPI result (S74). It is determined whether the result of the corresponding KPI exceeds the transfer order (S75).

  When an affirmative determination is made in process S75 and a negative determination is made in process S73 (that is, during the first period learning period), the instruction notification information determination unit 35 determines the result of the corresponding KPI calculated in the KPI result file. Is set (S76).

  Following the process S76 and when a negative determination is made in the process S75 (that is, when the calculated result of the corresponding KPI is equal to or less than the transfer order), the instruction notification information determination unit 35 determines the calculated KPI item. It is determined whether the processes S73 to S76 have been completed for all (S77). For example, the instruction notification information determination unit 35 can hold an end flag and determine whether to end according to the state of the end flag.

  When the determination in step S77 is affirmative, the instruction notification information determination unit 35 collects the KPI result file that summarizes the calculation results of the KPI items that satisfy the condition that the calculated KPI result exceeds the transfer order. Notify The collection information transfer unit 36 transfers the notified KPI result file to the collector 2 via the NET / IF 31 (S78). If the determination in step S77 is negative, the process returns to step S73.

Subsequent to the processing S78, processing in the next cycle is started (S79).
[Instruction notification information reception processing]
Next, an example of instruction notification information reception processing in the quality indicator processing system 1 according to an embodiment will be described with reference to FIGS. 1, 2, and 3 and related drawings. FIG. 8 shows a flow of instruction notification information reception processing in the monitoring device 3.

  In the quality indicator processing system 1, the instruction notification information receiving unit 37 of each monitoring device 3 receives the instruction notification information transmitted from the collector 2 via the NET / IF 32 (S81 in FIG. 8).

  The instruction notification information receiving unit 37 determines whether the received instruction notification information is information transmitted from the correct collector 2 (S82). That is, the instruction notification information receiving unit 37 is included in the instruction notification information that the collected information transfer unit 36 of the self-monitoring device 3 is the instruction notification information from the same collector 2 as the collector 2 that transmitted the KPI result file. Confirm based on the collector IP address (see FIG. 6).

  When the determination in step S82 is affirmative, the reception result storage processing unit 38 writes the received instruction notification information in the instruction notification information table 39 (S83). If the determination in step S82 is negative (that is, if the collector IP address is different), the instruction notification information is not written into the instruction notification information table 39.

  Subsequent to the process S83 and when a negative determination is made in the process S82, the process of the next cycle is started (S84).

  The instruction notification information reception process described above in the monitoring device 3 is a process at least one cycle later than the cycle of the quality index calculation process described with reference to FIG. However, this is not a problem for the following reasons.

  That is, each monitoring device 3 transfers the calculated KPI value to the collector 2 as a KPI calculation result only for KPI items that satisfy the transfer order as the transfer permission condition specified by the collector 2. Therefore, even if the collector 2 performs the instruction notification information transfer process, all the processes are accommodated within the same period. Further, since traffic in the network does not vary so much, there is no need to send instruction notification information from the collector 2 to each monitoring device 3 every period. Therefore, the processing of the collector 2 does not increase greatly as a whole.

[Quality index aggregation processing]
Next, an example of quality index (KPI) aggregation processing in the quality index processing system 1 according to one embodiment will be described with reference to FIGS. 1, 2, and 3 and related drawings. FIG. 9 shows a flow of quality index aggregation processing in the collector 2.

  In the quality index processing system 1, the KPI result file acquisition control unit 22 of the collector 2 receives the KPI result file transferred from each monitoring device 3 (S91 in FIG. 9).

  The KPI result file information analysis unit 23 reads the content (KPI value) of the KPI result file received from each monitoring device 3 from the corresponding buffer in the KPI result file acquisition control unit 22 and notifies the KPI aggregation unit 24 of it. The KPI result file information analysis unit 23 acquires KPI aggregation result information from the KPI aggregation result information storage unit 26A that stores the results aggregated at least one cycle before, and then instructs the instruction condition setting information table 26B. Condition setting information is acquired (S92, S93).

The KPI result file information analysis unit 23 determines whether or not processing S95 to S97 described later has been completed for all of the KPI items calculated in the monitoring device 3 (S94). For example, the KPI result file information analysis unit 23 holds an end flag and can determine the end according to the state of the end flag.

  If the determination in step S94 is negative, the KPI result file information analysis unit 23 indicates the KPI order in the corresponding KPI item stored in the KPI aggregation result information storage unit 26A as the KPI aggregation result information at least one cycle before, and indicates A multiplication value with the transfer order ratio in the corresponding KPI item stored in the instruction condition setting information storage unit 26B as condition setting information is obtained. Then, the KPI result file information analysis unit 23 determines whether the multiplication value (new order information) is different from the value of the transfer order (old order information) stored in the instruction condition setting information storage unit 26B (S95). .

  When an affirmative determination is made in step S95 (that is, when they are different), the KPI result file information analysis unit 23 stores the instruction notification information table 26C as the contents to be instructed to each monitoring device 3, and the instruction condition setting information. The transfer order information in the table 26B is updated to the new order information (S96, S97).

Following the process S97 and when the determination is negative in the process S95, the process returns to the process S94.
When the determination in step S94 is affirmative, the KPI result file information analysis unit 23 determines whether the content (instruction notification information) instructed to each monitoring device 3 exists in the instruction notification information table 26C (S98).

  If the determination in step S98 is affirmative, the KPI result file information analysis unit 23 calls the processing of the instruction notification information receiving unit 28 and the instruction notification processing unit 29, and transmits the instruction notification information to each monitoring device 3 via the NET / IF 21. (S98, S99).

  Subsequent to the process S99 and when a negative determination is made in the process S98, the KPI aggregation unit 24 aggregates the KPI calculation results, that is, aggregates and statistics, and calls the KPI aggregation result storage processing unit 25 (S100).

  The KPI aggregation result storage processing unit 25 stores the KPI aggregation result as KPI aggregation result information in the KPI aggregation result information storage unit 26A (S101).

Subsequent to the processing S101, processing in the next cycle is started (S102).
[Effect of one embodiment]
In the quality index processing system 1 described above, the collector 2 analyzes the contents (KPI value) of the KPI result file, and based on the analyzed result, a material for determining whether or not the transfer of the KPI calculation result is necessary (transfer permission condition) ) In the form of a transfer order. Each monitoring device 3 determines whether or not it is necessary to transfer the KPI calculation result based on this instruction content.

  As a result, the collector 2 receives the KPI calculation result from each monitoring device 3 only when necessary, so that the aggregation processing load on the collector 2 can be greatly reduced. Further, the size of the KPI result file transferred from each monitoring device 3 to the collector 2 is reduced, and not only the transfer load in each monitoring device 3 and the maintenance network 8 can be reduced, but also efficient monitoring operation is possible.
