The database 12 may be, for example, a database that stores information related to contracts that define communication quality provided to customers.

[Test of communication quality measurement initiated by test client device]
The test according to the present embodiment may be applied to, for example, an initial opening test (automatic opening test), or may be applied to a test performed thereafter (always test).
The operator terminal device 13 can communicate with the test server device 11 to transmit an instruction or information to the test server device 11 or receive information from the test server device 11. The test server device 11 may be controlled by the operator terminal device 13 as necessary, or may perform all processing automatically. The operator terminal device 13 is operated by an operator.

First, a process for providing information used for communication quality measurement from the test server device 11 to the test client device 21-1 will be described.
When the test client device 21-1 is not installed at the site (the place shown in FIG. 1), the worker brings the test client device 21-1 to the site and installs it. The installation location may be, for example, in the house (indoor). For example, the test client device 21-1 may be installed on site when necessary, or may be always installed (permanently) on site.

When the destination information (in this embodiment, the IP address) of the test client device 21-1 is not set in the test client device 21-1, the IP address is set in the test client device 21-1. As an example, the worker operates the input unit 341 of the test client device 21-1 to set the IP address. As another example, when the test client device 21-1 is communicably connected to the router device R51, the router device R51 may set the IP address to the test client device 21-1. The setting may be automatically performed. Information on the IP address set in the test client device 21-1 is stored in the storage unit 301.
Similarly to the setting of the IP address information, the identification information of the line used in the local network to which the test client device 21-1 is connected may be set and stored in the test client device 21-1. The line identification information is, for example, a line number (line number).

  The test client device 21-1 accesses the test server device 11. In the present embodiment, the test client device 21-1 logs into the portal page of the test server device 11. As an example, the operator operates the input unit 341 of the test client device 21-1, and the test client device 21-1 logs into the portal page of the test server device 11. As another example, the test client device 21-1 logs into the portal page of the test server device 11 according to a predetermined procedure. Information on the procedure is stored in the storage unit 301.

  The test client device 21-1 uses the request signal transmission unit 321 to send a communication quality measurement request signal including information identifying the local network to which the own device (the test client device 21-1) is connected to the backbone network B1. It transmits to the connected test server apparatus 11. As an example, an operator operates the input unit 341 of the test client device 21-1 to transmit the request signal. The operation may be a simple operation for the worker such as pressing (clicking) a predetermined button once. As another example, the test client device 21-1 may transmit the request signal at a predetermined timing, for example. The predetermined timing may be arbitrary, for example, a regular timing.

The test server device 11 sends the request signal for communication quality measurement transmitted from the test client device 21-1 by the request signal receiving unit 221 to the local network to which the test client device 21-1 is connected and the own device (the test device). The data is received via the backbone network B1 to which the server device 11) is connected.
The test server device 11 uses the specifying unit 222 to specify the local network to which the test client device 21-1 is connected based on the request signal received by the request signal receiving unit 221.

  Here, in the present embodiment, the test server apparatus 11 determines the communication status of the backbone network B1 by the communication quality measurement unit 225 before performing the communication quality measurement, and the determination result satisfies a predetermined condition. Next, the communication quality is measured. Moreover, the test server apparatus 11 may confirm reachability (communication is possible) with the test client apparatus 21-1 before that.

  For example, the test server device 11 uses the communication quality measurement unit 225 to detect the bandwidth usage rate (traffic status) of the backbone network B1. Then, the test server device 11 uses the communication quality measurement unit 225 to add a value obtained by adding a usage rate that is increased (expected) to the usage rate of the detected bandwidth to a predetermined value (for example, If the value exceeds 70), it is determined not to perform a communication quality measurement test. As a result, when the load of traffic flowing through the backbone network B1 is large, it is avoided that the traffic of the backbone network B1 is further increased by the test. On the other hand, in the test server device 11, the value obtained by adding the usage rate that is increased (and expected) by the test to the usage rate of the detected band by the communication quality measurement unit 225 is equal to or less than a predetermined value with respect to the maximum limit. In the case, it is determined to perform a communication quality measurement test.

When the test server apparatus 11 determines not to perform the communication quality measurement test, the test server apparatus 11 transmits a signal indicating the fact to the test client apparatus 21-1 to notify the test client apparatus 21-1.
As another configuration example, the test server device 11 uses a configuration in which the communication quality measurement unit 225 performs communication quality measurement without determining the communication status of the backbone network B1 before performing communication quality measurement. May be.

  When the communication quality measurement unit 225 determines that the communication quality measurement is to be performed, the test server device 11 accesses the test client device 21-1, logs in, and software necessary for performing the communication quality measurement. And the information of the setting contents is transmitted (uploaded) to the test client device 21-1. The software and the setting information may differ for each local network, for example. For upload (and download), for example, FTP (File Transfer Protocol) may be used.

The software and the setting content information include communication quality information corresponding to the local network. The specific example which provides the said communication quality information from the test server apparatus 11 to the test client apparatus 21-1 is shown.
That is, the test server device 11 uses the information acquisition unit 223 to store information for identifying a local network (network identification information) and information used for communication quality measurement (communication quality information) in association with each other (database). 12), information (communication quality information) used in communication quality measurement associated with the local network identified by the identifying unit 222 is acquired.
And the test server apparatus 11 transmits the information acquired by the information acquisition part 223 to the test client apparatus 21-1 by the information transmission part 224. As a result, the test server apparatus 11 transmits information used for communication quality measurement related to the local network specified by the specifying unit 222 to the test client apparatus 21-1 by the information transmitting unit 224.
Further, the test client device 21-1 receives information (communication quality information) used for communication quality measurement regarding the local network transmitted from the test server device 11 in response to the request signal by the information receiving unit 322.

  Here, the test client device 21-1 uses the IP address of its own device (the test client device 21-1) as information for specifying the local network in the communication quality measurement request signal transmitted to the test server device 11, or Include one or both of the line numbers used in the local network. In this case, the test server device 11 specifies the local network by the specifying unit 222 based on one or both of the IP address and the line number included in the request signal received by the request signal receiving unit 221. . In this case, the test server device 11 may use the specifying unit 222 with reference to the network configuration information stored in the storage unit 201. As another example, the test client device 21-1 may cause the router device R51 or the like to include the line number information in the communication quality measurement request signal by instructing the router device R51 or the like.

As another configuration example, information indicating a communication path may be added to a communication quality measurement request signal transmitted from the test client device 21-1. In this case, the test server device 11 specifies the local network based on the information indicating the communication path added to the request signal received by the request signal receiving unit 221 by the specifying unit 222.
Specifically, in the local network, there are devices such as a connection device (in this embodiment, the router device R51) that connects the test client device 21-1 to the local network. Identification information (referred to as device ID in this embodiment) is set for each device. When a communication quality measurement request signal passes through the connection device or the like, when the device ID of the connection device or the like is added to the request signal, the device ID may be used as information indicating a communication path.

  For example, information included in a data portion that configures a packet (or frame) may be used as information for specifying a network, or information included in a header that configures a packet (or frame) may be used. May be used. Information included in the header may be, for example, destination information, information indicating a communication path, information on a VLAN (Virtual LAN) identifier, or the like.

  Further, when the test server device 11 transmits communication quality information related to the local network by the information transmission unit 224, the test server device 11 follows the rules (rules) used in the local network for the QoS information included in the communication quality information. QoS information is used. Specifically, the QoS rule used on the backbone network B1 side is different from the QoS rule used on the local network, and the QoS rule used on the backbone network B1 side is used in the database 12. If there is, the information is transmitted after the test server apparatus 11 converts the information to the QoS information according to the QoS rules used in the local network by the information transmission unit 224. Note that the correspondence (rule) between the value used in QoS and its level (priority) may be different for each network.

A communication quality measurement test started by the test client device 21-1 will be described.
In the present embodiment, the test client device 21-1 continuously performs the communication quality measurement after receiving the communication quality information from the test server device 11. As another configuration example, the test client device 21-1 may perform the communication quality measurement at an arbitrary timing after receiving the communication quality information from the test server device 11.

By communicating bidirectionally between the test client device 21-1 and the test server device 11, communication quality measurement regarding the local network is performed.
The test client device 21-1 communicates with the test server device 11 via the local network and the backbone network B1 by the communication quality measurement unit 323, and performs communication quality measurement.
The test server device 11 performs communication quality measurement by communicating with the test client device 21-1 via the backbone network B1 and the local network by the communication quality measuring unit 225.

When the communication quality measurement is completed, the test client device 21-1 deletes the software and setting information necessary for performing the communication quality measurement received from the test server device 11.
As another configuration example, even when the communication quality measurement is completed, the test client device 21-1 deletes the software and setting information necessary for performing the communication quality measurement received from the test server device 11. You may hold without. In this case, the test client device 21-1 notifies the test server device 11 that the software and the setting content information necessary for performing communication quality measurement are held in the next test, thereby the information. May be omitted from the test server device 11 to the test client device 21-1.

Here, in the present embodiment, the communication quality measurement unit 225 of the test server device 11 and the communication quality measurement unit 323 of the test client device 21-1 measure the communication band, QoS, and delay time as communication quality measurement targets. I do.
Note that, for example, jitter, packet loss, test time, and fluctuation may be used as the communication quality measurement target. For example, communication quality measurement is performed for one or more objects. Further, the communication quality information of the network communication quality information 401 illustrated in FIG. 4 includes, for example, at least information related to a target on which communication quality measurement is performed.

The test server device 11 uses the communication quality measurement unit 225 to determine the result of communication quality measurement (result of the test). In the present embodiment, this determination is a determination that compares the result of communication quality measurement with the communication quality information (for example, contract information) of the network communication quality information 401 shown in FIG.
The test server apparatus 11 transmits information indicating the communication quality determination result to the test client apparatus 21-1 by the information transmission unit 224.
As another configuration example, a configuration may be used in which the test client device 21-1 performs part or all of the determination of the communication quality, and transmits the result information to the test server device 11 for notification. .

Here, communication quality determination will be described.
As an example, it is determined that the communication band [bit / s] is correctly set when a throughput of 80% or more of the communication band defined by the communication quality information is obtained as a result of the communication quality measurement. In other cases, it is determined that the setting is incorrect.
As an example, for each level of QoS [bit / s], when a throughput of 80% or more of the QoS of each level specified in the communication quality information is obtained as a result of the communication quality measurement, it is set correctly. judge. In other cases, it is determined that the setting is incorrect. Note that one or both of the test server device 11 and the test client device 21-1 transmit data labeled with the QoS label at each level, and measure the QoS.

As an example, the delay time [s] is correctly set when a delay time less than the value of the service level assurance (SLA) defined in the communication quality information is obtained as a result of the communication quality measurement. It is determined that In other cases, it is determined that the setting is incorrect.
In the present embodiment, round trip time (RTT) is measured. As a specific example, the test client device 21-1 measures the RTT by transmitting a Ping signal to each of the router device R32 and the router device R31 of the inter-network interface C1. In this case, information necessary for the measurement (for example, information on the IP addresses of the router devices R31 and R32) is transmitted from the test server device 11 to the test client device 21-1. In addition, the test client device 21-1 transmits information on the measurement result to the test server device 11 and notifies it.

[Communication quality measurement initiated by the test server]
