Abstract

PURPOSE:To attain reference of information of each node in a bundle by means of remote access and to leave the history of network operation information by providing a management processor to each node and collecting, editing and sending the maintenance operating information from each processor in a node periodically. CONSTITUTION:A management processor 5 is provided to each node being a remote station and a collection/transfer request of network operating information such as maintenance operating information is sent to each processor 6 sequentially through a timer 4, the information is collected, edited and transferred for each processor and stored in an area of the processor 5 corresponding to an information storage stack 8. The information for each processor 6 is referenced in a bundle via the stack 8 without implementing the access for each processor from a center 1 in response to the transfer request by the remote operation from the network management center 1. Furthermore, the history of network operating information is left by the stack 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a maintenance operation method for a network system, and particularly to remote maintenance suitable for implementing centralized management.

[Conventional technology]

Although it was possible to access any node, network operation information is held by each device in the exchange, so if you want to see it all at once, you need access to all devices. Information was obtained by starting a program for all relevant processors.

[Problem to be solved by the invention]

Although the above-mentioned conventional technology takes into consideration remote access, it does not take into consideration the processing method at the remote station. For example, in the case of a multiprocessor system where each processor has maintenance and operation information individually, it is not possible to read out the information at once. That is, it is necessary to access each processor each time.

The purpose of the present invention is to centrally manage maintenance and operation information from individual processors at remote stations using a single processor, and to enable remote access to read the information at the same time at the management center. It's about doing. At the same time, it is also intended to keep a history of network operation information and use it for maintenance.

[Means to solve the problem]

The above objectives are to adopt and equip remote access technology as shown in the prior art, to provide a new processor for centrally managing maintenance information, and to enable each processor to transfer information to the management processor. This is achieved by providing functions to do so. Remote access is
It is also possible to use conventional technology. In addition, even if you do not install a new processor, you can use one of the existing processors.
It is sufficient to allocate one. To transfer,
Possible methods include a method in which each processor independently transfers the data, or a method in which the management processor initiates the data transfer. Further, the trigger may be time or reception of an access signal. Here, we assume a method of starting from the management processor depending on the time of day.

[Effect]

The management center edits and sends a request signal to the corresponding remote station based on the input command. The remote station that receives the signal reads the information from the management processor according to the content of the signal, edits it, and responds.

When the timer reaches a certain period, the management processor sends a signal requesting each processor to collect and transfer network operation information. When this response is received, the processor number is recognized and the contents transferred to the corresponding area are stored. Repeat this for all processors.

Upon receiving the signal from the management processor, each individual processor collects network operational information scattered in memory and edits it for transmission. Put the edited data on the signal and return the response. Repeat collecting → editing → sending until all information has been transferred.

Through these, it is possible to collectively refer to the operation information of each node in this network.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. When a request is issued by a maintenance person or the like at the network management center 1, the network management center 1 sends out a request signal 21 as shown in FIG. 2 via the line 3. Here, 21 is an address field indicating the destination, 23 is a signal type indicating that it is maintenance information read request No. 1, and 2
4 is the type of read maintenance information. The management processor 5 of the remote station 2 that received the signal determines the information type 2 of the request signal.
4, the information is read out from the maintenance information stack area 8 of the station, the information is edited and stored in the information storage area 25, and a response is returned.

Storage in the maintenance information stack area 8 is performed by the management processor 5. The management processor 5 has a timer 4, and when a certain time comes, a maintenance information transfer request signal 31 is sent.
is transferred to each processor 6.

Here, 32 is an address field indicating the address of the destination processor, 33 is a signal type field indicating that the signal is a maintenance information transfer request signal, and 34 is a maintenance information storage area.

When the processor 6 receives the maintenance information transfer signal, it reads the maintenance information from the memory, stores it in the maintenance information storage area 34 on the signal, and returns a response to the management processor 6 via the bus 7. The management processor 6 stores the contents of the maintenance information storage area 34 of this signal in the star entry area 8. If the transfer has not been completed, the request signal 31 is transferred to the processor 6 again, and if the transfer has been completed, the process moves to the next processor 6. The process ends when all processors are processed.

〔Effect of the invention〕

According to the present invention, station maintenance information can be centrally managed. Furthermore, all information can be obtained from a network management center or the like by simply accessing one processor.

Furthermore, since it is collected periodically, it is possible to collect background information.

Therefore, there are effects such as being able to obtain information as a history of failures, improving maintenance efficiency by using the original pipe ring, and shortening response time during remote access.
