2. Description of the Related Art For example, in the case of measuring communication quality between terminal devices in a LAN (local area network), a measuring device is generally connected to a LAN transmission line and the measuring device is used to connect the transmission line. The information transmitted between the terminal devices is monitored, and the test information is transmitted from the measuring device to each terminal device as necessary to evaluate the response information including the response required time from the corresponding terminal device. .

Generally, when evaluating the communication quality of such a LAN, statistics such as communication error, traffic volume, average response time, and frequency distribution characteristic of communication volume within a predetermined period such as one day or one week are used. Evaluate in quantity. Therefore,
The measurement device is installed in one place for a long time and the measurement is performed.
In this case, the operator cannot stay in the vicinity of the measuring device for a long period of time, so the measurement plan is stored in the storage section of the measuring device and automatically based on the stored measurement plan. Each measurement is carried out.

In this case, when the operator creates a test plan on the measuring device, a GUI (graphical user interface) function is mounted on the operating portion of the measuring device to improve operability. There is.

Further, an X terminal incorporating X-Window System, which is software for multi-window display developed for UNIX system, is connected to the transmission line of the same LAN, and this X terminal is used. The measurement device may be controlled at a position different from the measurement device, or a test plan may be created.

[0006]

However, the measuring device incorporated in the above-mentioned LAN for measuring the communication quality of the LAN still has the following problems to be improved. That is, when a measurement plan is created using the GUI function incorporated in the measurement device, the operator needs to stay at the installation position of the measurement device for a long time, and
Every time the measurement plan is changed, it is necessary to go to the installation location of the measuring device.

Further, when the X terminal is used, the measuring device can be operated remotely and the measurement plan can be created by remote operation. In this case, the measuring device as a server that can be operated using the X terminal needs to be built in the same LAN.

However, when a plurality of networks or host computers are connected via a router such as the Internet, a measuring device incorporated in one LAN is controlled by an X terminal incorporated in another LAN. This is practically impossible because a security mechanism such as a firewall is incorporated near the router described above.

The present invention has been made in view of the above circumstances. For example, HTTP (hypertext transfer protocol) is mounted on a planning unit connected to a wide area network such as the Internet via a router, And for the planning department WWW (World Wide
By using a web browser, it is possible to create an execution plan for a planning unit from a different LAN by using a normal GU.
A remote control system via a wide area network that can be easily implemented by an operation using the I function and that can easily obtain an execution plan for an execution unit incorporated in a LAN installed at a distant place and an analysis of an execution result. The purpose is to provide.

[0010]

In order to solve the above problems, in a remote control system via a wide area network of the present invention, an execution unit for performing a predetermined process on the wide area network via a router, A planning section that creates an execution plan for the processing executed by this execution section, an analysis section that analyzes the execution results of the execution section, and a remote execution of the execution plan creation of the planning section and collect the analysis results of the analysis section It is connected to the operation unit that operates.

Then, the operation unit communicates with the planning unit by WWW.
It has means for remotely operating the preparation of an execution plan for the planning unit by exchanging information via the GUI by the browser, and means for displaying and outputting the analysis result transmitted from the planning unit. In addition, the planning unit adds means for transmitting screen information to the operation unit using HTTP, means for creating an execution plan based on the operation information received from the operation unit, and authentication information added to the created execution plan. And means for transmitting the execution plan to which the authentication information is added to the execution unit.

Further, when the authentication information attached to the execution plan received from the planning unit is valid, the execution unit sends a means for performing a predetermined process based on this execution plan and the execution result to the analysis unit. And means. The analysis unit has a unit for analyzing the execution result received from the execution unit and a unit for transmitting the analysis result to the operation unit.

In the remote control system via the wide area network configured as described above, the planning section
When entering various conditions for creating a test plan, do not actually enter the data such as the input of items and setting values or commands, but click the icons to display related (link) screens in sequence. A WWW browser for reading is adopted.

The operation unit belonging to a LAN different from the LAN to which the planning unit belongs via a wide area network reads the planning unit via the wide area network and exchanges information via the GIU by the WWW browser. Remotely create the execution plan of the planning department. That is, the operator sequentially clicks each displayed item with, for example, a mouse. Note that the screen information is transmitted from the planning unit to the operation unit using HTTP (Hypertext Transfer Protocol).

The execution plans created by the planning unit are transferred to the execution units belonging to different LANs via the wide area network. In this case, since authentication information such as a password is added to the execution plan transmitted to the execution unit, a third party can easily execute even an execution instruction to the execution unit using the open wide area network. The execution part cannot be controlled.

In the execution unit, only when the authentication information is valid, a predetermined process is executed according to the received execution plan, and the execution results are different LANs via the wide area network.
Is transferred to the analysis unit belonging to. In the analysis unit, the execution result is analyzed, and the analysis result is transferred to the operation unit and displayed on the operation unit. Therefore, the operator can grasp the analysis result on the operation unit.
