Or, monitoring is performed to operate or use the system.

In this case, conventionally, data for monitoring is regularly communicated between an information processing device such as a computer for managing or monitoring and a component device of a system forming a network, and component device I try to understand the operating status information such as.

However, in such a system,
Between the information processing device such as a computer that manages or monitors and the component devices of the system that configures the network,
Since the monitoring data is regularly communicated and the operating status information of the component devices and the like is grasped, monitoring data other than the actual operation data is frequently communicated in the system. The traffic volume of the entire system increases. As a result, there is a problem that the responsiveness of the system is deteriorated or that the communication facility capacity necessary for operation must be constructed more than necessary.

[0005]

As described above, in the conventional system, the traffic volume of the entire system is large and the responsiveness of the system is deteriorated, or the communication equipment capacity necessary for operation is constructed more than necessary. There was a problem that had to be.

An object of the present invention is to reduce unnecessary data communication by combining general operation data and monitoring data, reduce the traffic volume of the entire system, and improve the responsiveness of the system. It is to provide an extremely reliable network system capable of drawing out a capacity close to the equipment capacity.

[0007]

In order to achieve the above object, according to the present invention, in a system that forms a network using communication equipment, a system between a monitoring device and a monitored device that constitutes the system during system operation is provided. A first general data processing means for creating general operational data to be communicated at the time of operating the system in a network system in which some data is communicated with each other to monitor the operation status of network constituent devices; Monitoring data addition processing means that automatically adds monitoring data for monitoring / management to general operation data created by the general data processing means, and processing data from the monitoring data addition processing means is monitored as a composite data format. The composite data creation processing means to be transmitted to the device and the communication of the monitoring data are decided according to the instruction data from the monitoring device.
