Description

Description: TECHNICAL FIELD The present invention relates to a network communication state management system.

[Conventional technology]

Conventionally, in a communication management in a network, a terminal device constituting the network independently manages a communication state, and management of a communication state of the entire network is left to each terminal device.

[Problems to be solved by the invention]

The above-described conventional network communication state management method has a drawback in that it is impossible to monitor and control the communication state in the network and the trouble of the terminal device in real time when a large-scale network configuration is implemented.

[Means for solving the problem]

A communication state management method for a network according to the present invention includes a communication monitoring device having a table for storing connection information between terminal devices that perform inter-network communication, and a calling terminal device in the network from a calling terminal device to a called terminal device. A communication start / communication release ID indicating the communication start or communication release to the communication monitoring device, and address information of the calling terminal device and the called terminal device when the communication start or communication release is set by the communication monitoring device. Means for sending start / communication release notification data; means for registering or deleting the address information in the table in accordance with the instruction of the communication monitoring device; and for any terminal device in the network in accordance with the instruction of the communication monitoring device. Means for transmitting diagnostic data for recognizing a power-off or communication failure at a fixed time unit. When the device receives the notification data, if the communication start / release ID indicates communication start, the address information of the calling terminal device and the called terminal device is registered in the table, and the address information is stored in the table. The diagnostic data is sent to the calling terminal and the called terminal. If the communication start / release ID indicates communication release, the calling terminal and the called terminal are read from the table. It is characterized in that the terminal address information is deleted.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention and is a network configuration diagram in which a communication monitoring device 1 is arranged. The network includes a network system 2, the communication monitoring device 1, the terminal device 3 ₁ to 3
_{Let n + 2} be a component.

FIG. 2 is a detailed view of the communication monitoring device 1 and a line adapter for receiving data from a terminal device in the network.
101, memory 102, data register 103, control processor 104
The control processor 104 has a function of updating the inter-node management table 105 with data received from the terminal device.

Figure 3 is to inter-node management terminal registered in the table 105 device 3 ₁ to 3 _{n + 2,} shows the format of the diagnostic data sent from the communication monitoring device 1 at regular intervals.

FIG. 4 shows a communication start / communication to be transmitted to the communication monitoring device 1 when the terminal devices 3 _{1 to} 3 _{n + 2} start communication with another terminal device in the network or when the communication is released. Indicates the format of release notification data.

As an example of a network management system, the case of performing communication with the terminal device 3 _{n + 1} via the network 2 from the terminal apparatus 3 ₁ below.

The terminal apparatus 3 ₁ knows the node address of the communication monitoring device 1 and the terminal device 3 _{n + 1,} prior to communicating with the terminal device 3 _{n + 1,} the communication start notification data 5 in the communication monitoring device 1 start of the communication ID 501, the requesting node address of the terminal device 3 ₁ source terminal device node address 502, respectively set to send a node address of the terminal device 3 _{n + 1} to the communication destination terminal node address 503.

Communication monitoring device 1 stores the node address of the communication start notification data 5 received in the inter-node management table 105, thereafter, the terminal apparatus 3 ₁ communicates with the terminal device 3 _{n + 1.}

On the other hand, the communication monitoring device 1 that has received the communication start notification data 5 sets the diagnostic data ID 401 according to the format of the diagnostic data 4 at regular intervals from the node information of the terminal device registered in the inter-node management table 105, Send to terminal device.

The terminal device that has received the status 40
When a communication error occurs again in 2, the detailed code is set in the detailed status 403, and a response is made to the communication monitoring device 1.

Upon receiving the response, the communication monitoring device 1 reflects the status of the terminal device in the inter-node management table 105.

When the terminal device releases the communication, the communication release notification data 5 includes the communication release ID 501 and the requesting terminal device node address.
502 and the communication destination terminal device node address 503 are set and transmitted to the communication monitoring device 1. Communication release notification data 5
The communication monitoring device 1 that has received the
From 5, the corresponding information in the terminal device address of the communication release notification data 5 is deleted, and the communication state in the network is managed.

〔The invention's effect〕

As described above, the present invention has a communication monitoring device in a network composed of a plurality of terminal devices, and collectively monitors the communication state of the terminal device performing communication or trouble of the terminal device itself by the communication monitoring device. And can be controlled.
