[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, a specific example when the first communication is voice communication will be described.

  First, FIG. 3 shows a configuration example of the communication system of the present embodiment.

  The communication system according to the present embodiment includes a communication monitoring device 20, a voice communication device 60, and a network device 70. The number of voice communication devices 60 and network devices 70 is one or more and is arbitrary.

  The network device 70 is a network device (for example, a router) that exists on a communication network and transfers communication data.

  The voice communication device 60 is a device that performs voice communication, such as a VoIP terminal or a SIP (Session Initiation Protocol) server. The voice communication device 60 transmits and receives voice communication data via the network device 70.

  The communication monitoring device 20 is a device that monitors the voice communication device 60 and the network device 70.

  Next, FIG. 4 shows a configuration example of the communication monitoring apparatus 20 of the present embodiment. The communication monitoring device 20 includes a first communication information collection unit 11, a network information collection unit 12, an output unit 13, a first communication information storage unit 24, an analysis unit 25, and a network control unit 26.

  The 1st communication information collection part 11 is a part which collects the 1st communication relevant information regarding 1st communication. The first communication information collection unit 11 of the present embodiment collects session information (voice session information) and voice quality information of the first communication from the voice communication device 60 as the first communication related information. The first communication information collection unit 11 collects first network related information related to the first communication from the network information collection unit 12. Note that the first network-related information is traffic information (voice traffic information) related to voice communication in the present embodiment. The first communication information collection unit 11 stores the collected first communication related information in the first communication information storage unit 24.

  The network information collection unit 12 is a part that collects network related information including information related to communications other than the first communication from the network device 70 to be monitored. The network related information is, for example, network topology information, traffic information, routing information, and the like. The network related information includes the second network of the first network related information (voice traffic information) related to the first communication and the other communication (second communication) using the communication path used by the first communication. Contains related information. The network related information may further include not only the network related information of the network device 70 on the communication path used by the first communication but also network related information of the entire system.

  FIG. 5 shows an example of the first communication related information stored in the first communication information storage unit 24. In this example, the first communication information storage unit 24 stores a voice session table (FIG. 5A), a voice communication table (FIG. 5B), and a voice route table (FIG. 5C).

  The voice session table is a table for storing a session ID (Identification) (SID) of voice communication, voice session information and voice quality information corresponding to the session ID. The voice session information is, for example, a combination of a source IP address and a destination IP address for voice communication, a combination of a source port number and a destination port number, or the like. The voice quality information is, for example, a MOS (Mean Opinion Score) value or an R value (Rating factor).

  As a method for collecting MOS values, for example, a method of mounting a button for evaluating voice quality on the voice communication device 60 and actually allowing the user to evaluate the quality can be considered. Alternatively, a method of estimating the MOS value based on objective evaluation such as PESQ (Perceptual Evaluation of Speech Quality) may be used.

  The voice communication table is a table that stores the session ID of the terminated voice session, the route information corresponding to the session ID, and the voice traffic information. The route information is, for example, identification information of the network device 70 through which the voice session has passed or a list of IP addresses, a combination of a start time and an end time of use of the route. The voice traffic information is, for example, statistical information such as the throughput, the amount of packets, the number of packet drops, etc. regarding the voice session of the network device 70 on the route. If there is a route change during the establishment of the voice session, the voice communication table stores the route information before and after the change.

  The voice route table is a table that stores route information of a communication route used in the currently established voice session. The voice route table stores a session ID, route information corresponding to the session ID, and use start time. The route information is, for example, identification information or a list of IP addresses of the network device 70 through which the voice session passes. The use start time is the time when the use of the route is started. When a route change occurs during session establishment, the voice route table stores route information before and after the change for the same session ID.

  When a certain voice session is started, the first communication information collecting unit 11 acquires the voice session information and the voice quality information from the voice communication device 60, and the voice session table of the first communication information storage unit 24 (FIG. 5 ( a)).

  Further, the first communication information collection unit 11 acquires the route information used in the voice session from the network information collection unit 12 and stores it in the voice route table of the first communication information storage unit 24 (FIG. 5C )).

  For example, the network information collection unit 12 can obtain the route information by referring to the routing table of each network device 70 and following the route from the source IP address to the destination IP address of the voice session. That is, the network information collection unit 12 acquires the routing table of the network device 70 using the network device 70 of the transmission source IP address as a start point and using SNMP (Simple Network Management Protocol). Then, the IP address of the network device 70 of the next hop to go to the destination IP address is acquired from the routing table. The network information collection unit 12 can acquire route information by repeating this operation until the destination IP address is reached.

  Further, the network information collecting unit 12 may detect a route change of the voice session by referring to the routing table of the router on the route every predetermined time, and acquire the route information again by the above-described method. it can.

  After the voice session is started, the first communication information collection unit 11 collects the voice quality information at a predetermined timing such as every predetermined time and stores it in the voice session table of the first communication information storage unit 24.

  When the voice session ends, the first communication information collection unit 11 acquires the voice traffic information related to the voice session from the network information collection unit 12 and stores it in the first communication information storage unit 24. Specifically, the first communication information collecting unit 11 obtains the voice session route information from the voice route table (FIG. 5C) of the first communication information storage unit 24, and the voice session table (FIG. 5). Voice session information is acquired from (a)). And based on these information, the voice traffic information on a path | route is acquired from the network information collection part 12, and it is made to memorize | store in the voice communication table ((b) of FIG. 5) of the 1st communication information storage part 24. FIG.

  The output unit 13 is a part that outputs first communication information (voice session information, voice quality information, voice traffic information) and network related information. For example, the output unit 13 outputs and displays the first communication information and the network related information to the display device.

  The output unit 13 outputs the first communication information and the network related information to the analysis unit 25 in response to a request from the analysis unit 25. In the present embodiment, the output unit 13 obtains the information requested from the analysis unit 25 via the first communication information collection unit 11, the network information collection unit 12, or the first communication information storage unit 24, The obtained information is output to the analysis unit 25.

  In the case of this embodiment, the types of information requested from the analysis unit 25 are (1) voice related information (voice session information, voice quality information), (2) voice traffic information, and (3) a network not limited to voice communication. There are three types of related information. Multiple types of information may be requested at the same time.

  The request from the analysis unit 25 includes identification information that identifies the voice session. In the case of a request for network related information, information specifying which communication traffic information is requested is included. For example, a source / destination IP address, a source / destination port number, or the like may be used as a traffic identification method.

  When the analysis unit 25 requests (1) voice related information, the output unit 13 confirms the first communication information storage unit 24, and if the voice session for which information is requested is being established, the output unit 13 The communication information collection unit 11 is requested for voice related information. The first communication information collecting unit 11 that has received the request outputs the information to the output unit 13 every time the voice related information is acquired from the voice communication device 60. When the voice session for which information is requested has ended, the output unit 13 acquires the voice related information from the voice session table ((a) of FIG. 5) of the first communication information storage unit 24. Then, the output unit 13 outputs the voice related information to the analysis unit 25.

  When the voice traffic information is requested from the analysis unit 25 (2), the output unit 13, when the voice session for which the information is requested has ended, the voice communication table (see FIG. Voice traffic information is acquired from (b) of 5).

  If the voice session for which information is requested is being established, the output unit 13 obtains the voice session information from the voice session table ((a) of FIG. 5) of the first communication information storage unit 24, and the voice route table (FIG. 5 (c)), route information is acquired. Based on the information, the output unit 13 acquires the voice traffic information of the voice session from the network information collection unit 12 at predetermined time intervals. Then, the output unit 13 outputs the acquired voice traffic information to the analysis unit 25.

  Note that the output unit 13 may acquire and output not only the voice traffic information but also the traffic information of the peripheral route of the communication route used in the voice communication. For example, when the output unit 13 acquires the voice traffic information from the network information collecting unit 12, the output unit 13 acquires the surrounding traffic information together with the voice traffic information. Alternatively, at the start of monitoring, the output unit 13 notifies the first communication information collection unit 11 of information indicating that peripheral traffic information is also acquired. Then, the first communication information collection unit 11 stores the surrounding traffic information in the first communication information storage unit 24 together with the voice traffic information. The information indicating that peripheral traffic information is also acquired is, for example, a numerical value indicating how many hops of network device traffic information is acquired from a route used in voice communication. Since the voice quality may be improved by switching the route when the voice quality is deteriorated, the communication monitoring device 20 acquires not only the traffic information of the route being used but also the traffic information of the surrounding route. It is desirable.

  When (3) network-related information is requested from the analysis unit 25, the output unit 13 acquires the network-related information from the network information collection unit 12 and outputs the acquired network-related information to the analysis unit 25.

  The analysis unit 25 is a part that performs analysis such as identification of a cause of voice quality deterioration and investigation of factors, determines an improvement plan for improving the voice quality, and makes a network control request according to the improvement plan. The analysis unit 25 requests information to be used for analysis from the voice related information, voice traffic information, and network related information to the output unit 13. Then, based on the information output from the output unit 13, the analysis unit 25 analyzes the presence / absence of voice quality deterioration, the part where it is deteriorated, and the cause thereof. The analysis unit 25 further determines an improvement plan for improving the voice quality deterioration according to the analysis result, and makes a network control request to the network control unit 26.

  The analysis unit 25 can determine the problem location and the cause thereof based on, for example, which parameter information value of which network device 70 is deteriorating. In addition, the analysis unit 25 takes improvement measures such as changing the voice communication path so as to bypass the network device 70 whose performance is deteriorated, and changing the priority setting set in each network device 70. Can be determined.

  The network control unit 26 is a part that controls the network device 70 in accordance with a network control request from the analysis unit 25. By making a network control request corresponding to the improvement plan from the analysis unit 25 to the network control unit 26, the network control unit 26 can control the network device 70 according to the improvement plan.

  By configuring the communication monitoring device 20 in this way, the communication monitoring device 20 collects network-related information including information related to communication other than the first communication from the monitored network device. The network related information includes not only network related information related to the first communication but also network related information related to other communication. Therefore, it is possible to collect network information related to other communications together with information related to specific communications and use it for improving the quality of specific communications.

  Next, an operation example of the communication monitoring apparatus 20 according to the present embodiment will be described with reference to FIGS. FIG. 6 is a diagram illustrating an operation example of the network information collection unit 12 of the communication monitoring apparatus 20 according to the present embodiment.

  First, an operation example of the network information collecting unit 12 will be described with reference to FIG. The network information collecting unit 12 collects network related information from the network device 70 every predetermined time (step S201). If a route change related to the voice session is detected (YES in step S202), the route change is notified to the first communication information collection unit 11 (step S203). When a request for network related information or voice traffic information is received from the first communication information collection unit 11 or the output unit 13 (YES in step S204), the requested information is returned to the request source (step S205). .

  Next, an example of the operation of collecting voice related information and voice traffic information of the first communication information collecting unit 11 will be described with reference to FIG.

  When a certain voice session is started (YES in step S301), the first communication information collecting unit 11 acquires the voice session information from the voice communication device 60, and the voice session table (see FIG. 5 (a)). Further, the first communication information collection unit 11 acquires the route information used in the voice session from the network information collection unit 12 and stores it in the voice route table of the first communication information storage unit 24 (FIG. 5C )) (Step S302).

  After the voice session is started, the first communication information collection unit 11 collects the voice quality information at a predetermined timing such as every predetermined time and stores it in the voice session table of the first communication information storage unit 24 ( Step S303).

  When a route change occurs (YES in step S304), the first communication information collection unit 11 acquires route information from the network information collection unit 12, and the voice route of the first communication information storage unit 24 is obtained. It is stored in the table (step S305). The first communication information collection unit 11 acquires the voice traffic information before the route change from the network information collection unit 12 and stores it in the voice communication table of the first communication information storage unit 24 (step S306).

  When the voice session is ended (YES in step S307), the first communication information collection unit 11 acquires the voice traffic information of the voice session from the network information collection unit 12, and the first communication information storage unit 24 performs voice communication. It is stored in the table (step S308).

  Next, an operation example of the output unit 13 when a request for voice related information is received from the analysis unit 25 will be described with reference to FIG.

  The output unit 13 receives a request for voice related information from the analysis unit 25 (YES in step S401). Next, if the voice session for which information is requested is being established (NO in step S402), the output unit 13 requests voice-related information from the first communication information collection unit 11 (step S403). When a request for voice related information is received from the output unit 13, the first communication information collection unit 11 outputs the voice quality information every time the voice quality information is acquired from the voice communication device 60 in step S308 of FIG. 13 to output. The output unit 13 outputs the information to the output unit 13 every time the voice related information is received from the first communication information collection unit 11 (YES in step S404) (step S405). When the information indicating that the request is completed is received (YES in step S406), the output unit 13 notifies the first communication information collection unit 11 of the completion of the request, and the first communication information collection unit 11 outputs the output unit. The output of the voice related information to 13 is terminated (step S407).

  When the voice session for which information is requested has ended, the output unit 13 acquires and outputs the voice related information from the voice session table ((a) of FIG. 5) of the first communication information storage unit 24. (Step S408, Step S409).

  Next, an exemplary operation of the output unit 13 when a request for voice traffic information is received from the analysis unit 25 will be described with reference to FIG.

  The output unit 13 receives a request for audio related information regarding a certain audio session from the analysis unit 25 (YES in step S501). Next, when the voice session has ended (YES in step S502), the voice traffic information is recorded in the voice communication table of the first communication information storage unit 24 in step S308 of FIG. Therefore, the output unit 13 acquires information from the voice communication table and outputs it (steps S503 and S504).

  If the voice session has not ended (NO in step S502), the output unit 13 acquires session information from the voice session table of the first communication information storage unit 24 and route information from the voice route table (step S505). . And based on those information, the voice traffic information regarding the said voice session is acquired from the network information collection part 12 for every predetermined time, and is output (step S506, step S507).

  When the request end message is received from the analysis unit 25 (YES in step S508), the output unit 13 ends the processes in steps S506 and S507. The request end message may be intentionally transmitted by the administrator or the like via the analysis unit 25, or may be automatically transmitted by the administrator closing the GUI screen displayed on the display device. It is also possible.

  Even if the interval at which the output unit 13 acquires the voice traffic information is reduced, if the network-related information collected by the network information collection unit 12 is not updated during that time, the output unit 13 may obtain new information. Can not. Therefore, it is desirable that this interval is equal to or greater than the interval at which the network information collection unit 12 collects network related information.

  Next, an operation example of the output unit 13 when receiving a request for network related information related to communication other than a voice session from the analysis unit 25 will be described. This operation example is similar to the operation example (FIG. 9) when the output unit 13 is requested for voice session information. Therefore, an operation example of the output unit 13 when network-related information is requested will be described with reference to FIG. 9 is replaced with “network-related information” and “from the first communication information storage unit” in step S503 is replaced with “from the network information collection unit”.

  The output unit 13 receives a request for network related information from the analysis unit 25 (YES in step S501). Next, when the voice session has ended (YES in step S502), the output unit 13 acquires the voice session information from the voice session table of the first communication information storage unit 24 and the route information from the voice communication table. . Based on the information, network-related information related to communication other than the voice session is acquired from the network information collecting unit 12 (step S503) and output (step S504).

  When the voice session is being established (NO in step S502), the output unit 13 acquires voice session information from the voice session table of the first communication information storage unit 24 and route information from the voice route table (step S505). . Then, based on the information for identifying other communication received from the analysis unit 25, the voice session information, and the route information, the network information collection unit 12 acquires network-related information for the specific communication (step S506). ) And output (step S507).

  When the request end message is received from the analysis unit 25 (YES in step S508), the output unit 13 ends the repetition of step S506 and step S507.

  By operating in this way, the communication monitoring apparatus 20 collects network related information including information related to communication other than the first communication from the network device to be monitored. The network related information includes not only network related information related to the first communication but also network related information related to other communication. Therefore, it is possible to collect network information related to other communications together with information related to specific communications and use it for improving the quality of specific communications.

  As described above, in the second embodiment of the present invention, the communication monitoring device 20 collects network-related information including information related to communication other than the first communication from the network device to be monitored. The network related information includes not only network related information related to the first communication but also network related information related to other communication. Therefore, it is possible to collect network information related to other communications together with information related to specific communications and use it for improving the quality of specific communications.

  In addition, the network information collection unit 12 of the communication monitoring apparatus 20 according to the present embodiment collects network information without being limited to the network information of voice communication on the route and other specific communications. And the output part 13 of the communication monitoring apparatus 20 can acquire the desired data flexibly by acquiring necessary information from the network information collected by the network information collecting part 12 at a necessary timing. The necessary data may be limited if it is used for monitoring and understanding of the cause of the problem, but considering the control for improving the voice quality, the topology and traffic information around the voice communication path can be obtained. Various data will be required. Since necessary data varies depending on the situation, it is difficult to specify and collect necessary data in advance. Therefore, a mechanism that can collect necessary data appropriately is important.

  Further, since the network information collecting unit 12 collects network related information independently of the voice related information, it is easy to use the collected network related information in other services other than the voice communication monitoring service. For example, it can also be used for general network monitoring / control services not limited to voice communication. Therefore, it is not necessary to prepare a mechanism for collecting network information for each service to be used.

  On the other hand, the communication monitoring apparatus 20 according to the present embodiment collects voice-related information and network-related information independently, and thus extracts and acquires voice traffic information corresponding to a voice session from a large amount of network-related information. There is a need to. The first communication information collection unit 11 of the communication monitoring apparatus 20 according to the present embodiment records and manages communication path information used in each voice session together with voice related information. Thereby, the first communication information collection unit 11 can acquire information from the network information collection unit 12 by clearly specifying which traffic information of which network device in which period is necessary. Therefore, the first communication information collection unit 11 of the present embodiment can acquire necessary voice traffic information efficiently (low delay).

  In addition, the communication monitoring apparatus 20 according to the present embodiment stores the voice traffic information in the first communication information storage unit 24, but appropriately stores the network related information of other communication that seems to be less frequently used without being stored. Have acquired. There is a trade-off between information acquisition delay and information acquisition processing cost, but the information acquisition delay and acquisition processing cost can be optimized by properly using information stored in the database and information acquired as appropriate. Can be achieved.
