[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, a specific example in the case where 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 of this embodiment is composed of a communication monitoring device 20, a voice communication device 60, and a network device 70. The number of the voice communication device 60 and the network device 70 may be one or more and is arbitrary.

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

The voice communication device 60 is a device that performs voice communication, such as a VoIP terminal and a SIP (Session Initiation Protocol) server. The voice communication device 60 transmits / 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 device 20 of the present embodiment. The communication monitoring device 20 is composed of a first communication information collecting unit 11, a network information collecting unit 12, an output unit 13, a first communication information storage unit 24, an analysis unit 25, and a network control unit 26.

The first communication information collecting unit 11 is a part that collects the first communication-related information related to the first communication. The first communication information collecting 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. Further, the first communication information collecting unit 11 collects the first network-related information related to the first communication from the network information collecting unit 12. In this embodiment, the first network-related information is traffic information (voice traffic information) related to voice communication. Further, the first communication information collecting unit 11 stores the collected first communication-related information in the first communication information storage unit 24.

The network information collecting unit 12 is a part that collects network-related information including information related to communication other than the first communication from the network device 70 to be monitored. Network-related information includes, for example, network topology information, traffic information, routing information, and the like. In addition, the network-related information is 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 relevant 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 the 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. 5 (a)), a voice communication table (FIG. 5 (b)), and a voice path table (FIG. 5 (c)).

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

As a method of collecting the MOS value, for example, a method of mounting a button for evaluating the voice quality on the voice communication device 60 and having the user actually evaluate the quality can be considered. Alternatively, a method of estimating the MOS value based on an 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 completed voice session, and the route information and voice traffic information corresponding to the session ID. The route information is, for example, identification information or a list of IP addresses of the network device 70 through which the voice session has passed, a combination of a time when the route is started and a time when the route is used, and the like. The voice traffic information is, for example, statistical information such as throughput, packet amount, and number of packet drops related to the voice session of the network device 70 on the route. If the route is changed 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 the route information of the communication route used in the voice session currently being established. The voice route table stores the session ID, the route information corresponding to the session ID, and the usage start time. The route information is, for example, a list of identification information and IP addresses of the network device 70 through which the voice session is passing. The use start time is the time when the use of the route is started. If a route change occurs during session establishment, the voice route table stores the 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 (FIG. 5). Store in a)).

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

The network information collecting unit 12 can acquire 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, for example. That is, the network information collecting unit 12 acquires the routing table of the network device 70 by using the network device 70 of the source IP address as a starting point and using SNMP (Simple Network Management Protocol). Then, from the routing table, the IP address of the network device 70 of the next hop to go to the destination IP address is acquired. The network information collecting unit 12 can acquire route information by repeating this operation until the destination IP address is reached.

Further, the network information collecting unit 12 can detect the route change of the voice session by referring to the routing table of the router on the route at predetermined time intervals, and acquire the route information again by the above method. can.

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

When the voice session ends, the first communication information collecting unit 11 acquires voice traffic information related to the voice session from the network information collecting unit 12 and stores it in the first communication information storage unit 24. Specifically, the first communication information collecting unit 11 obtains the route information of the voice session from the voice route table ((c) of FIG. 5) of the first communication information storage unit 24, and the voice session table (FIG. 5). Acquire voice session information from (a)). Then, based on this information, voice traffic information on the route is acquired from the network information collecting unit 12, and stored in the voice communication table ((b) of FIG. 5) of the first communication information storage unit 24.

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

Further, the output unit 13 outputs the first communication information and 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 the present embodiment, the types of information requested from the analysis unit 25 are not limited to (1) voice-related information (voice session information, voice quality information), (2) voice traffic information, and (3) voice communication. There are three types of related information. Multiple types of information may be required at the same time.

The request from the analysis unit 25 includes identification information that identifies the voice session. Also, in the case of requesting network-related information, information that identifies which communication traffic information is requested is included. As a method of identifying traffic, for example, a source / destination IP address, a source / destination port number, and the like can be considered.

When (1) voice-related information is requested from the analysis unit 25, the output unit 13 confirms the first communication information storage unit 24, and if the voice session for which the information is requested is being established, the first Request voice-related information from the communication information collection unit 11. Upon receiving the request, the first communication information collecting unit 11 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 voice-related information from the voice session table ((a) in 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 (2) voice traffic information is requested from the analysis unit 25, the output unit 13 outputs the voice communication table of the first communication information storage unit 24 when the voice session for which the information is requested has ended (FIG. Voice traffic information is acquired from 5 (b)).

If the voice session for which information is requested is being established, the output unit 13 obtains voice session information from the voice session table (FIG. 5 (a)) of the first communication information storage unit 24 and the voice route table (FIG. 5). Route information is acquired from 5 (c)). Then, 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.

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 voice traffic information from the network information collection unit 12, it also acquires peripheral traffic information together with the voice traffic information. Alternatively, at the start of monitoring or the like, the output unit 13 notifies the first communication information collection unit 11 of information that the peripheral traffic information is also acquired. Then, the first communication information collecting unit 11 stores the peripheral traffic information as well as the voice traffic information in the first communication information storage unit 24. The information to acquire the peripheral traffic information is, for example, a numerical value indicating how many hops of traffic information of the network device is acquired from the route used for voice communication. Since there is a possibility that the voice quality is improved by switching the route when the voice quality deteriorates, the communication monitoring device 20 acquires not only the traffic information of the route being used but also the traffic information of the peripheral route. Is desirable.

(3) When the analysis unit 25 requests the network-related information, 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 analyzes the cause of the deterioration of voice quality, investigates the cause, 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 the output unit 13 to use information for analysis from the voice-related information, the voice traffic information, and the network-related information. Then, the analysis unit 25 analyzes whether or not the voice quality is deteriorated, the portion where the voice quality is deteriorated, and the cause thereof based on the information output from the output unit 13. The analysis unit 25 further determines an improvement plan for improving the voice quality deterioration according to the result of the analysis, and makes a network control request to the network control unit 26.

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

The network control unit 26 is a part that controls the network device 70 according to the network control request from the analysis unit 25. By making a network control request from the analysis unit 25 to the network control unit 26 according to the improvement plan, 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 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 communication together with information related to specific communication and use it for improving the quality of specific communication.

By operating in this way, 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 communication together with information related to specific communication and use it for improving the quality of specific communication.

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 communication together with information related to specific communication and use it for improving the quality of specific communication.

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

Further, since the network information collecting unit 12 collects the network-related information independently of the voice-related information, it is easy to use the collected network-related information in services other than the voice communication monitoring service. For example, it can be used for general network monitoring and control services that are 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, since the communication monitoring device 20 of the present embodiment independently collects voice-related information and network-related information, voice traffic information corresponding to a certain voice session is extracted from a large amount of network-related information and acquired. There is a need to. The first communication information collecting unit 11 of the communication monitoring device 20 of the present embodiment records and manages the communication path information used in each voice session together with the voice-related information. As a result, the first communication information collecting unit 11 can acquire information from the network information collecting unit 12 by clearly designating which traffic information of which network device in which period is required. Therefore, the first communication information collecting unit 11 of the present embodiment can efficiently (low delay) acquire the necessary voice traffic information.
