DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection method for a network monitoring device, and more particularly, to a network monitoring device for monitoring the status of a network device, the monitoring function of the network monitoring device being changed in accordance with the replacement of the network device or the change of the monitoring operation. Connection method.

[0002]

2. Description of the Related Art The connection system of this type of conventional network monitoring device will be described below. FIG. 3 is a block diagram showing the configuration of the conventional system. Referring to FIG. 3, a package 100 on which network device 12 is mounted
Is newly connected, the interrupt generation device 10 mounted on the package 100 generates an interrupt signal in order to inform the network monitoring device 300 on the management system side of “connection”.

The network monitoring device 300 includes an interrupt detection device 20 for receiving an interrupt signal transmitted from the interrupt generation device 10 via the communication path 200. The interrupt detection device 20 stores a database 2 ( For example, MIB (Management Info
3) that the network device 12 is connected. The database 23 propagates this notification, that is, the notification that the network device 12 is connected, to the worker 400. That is, the worker 400 is notified that a predetermined operation for activating the connection state of the network device 12 is required.

[0004] In response to this notification, the worker 400 changes the information (for example, MIB data) in the database 23 to activate the connection state of the network device 12.

[0005]

However, in the above-mentioned conventional connection method, every time a new network device is connected, it is necessary to notify the worker of the new connection and perform the necessary work manually. However, there is a problem that labor saving of work cannot be achieved.

Further, in order to activate the connection state of the newly connected network device, operations such as addition and correction of database information are manually performed in the network monitoring device. It is not expected that the connection state will be activated immediately when an interrupt is sent from the interrupt generation means.Therefore, there is a problem in responsiveness, and there is a possibility that an artificial error such as an operation error may occur. Has a problem in terms of reliability.

[0007] The reason why the above-mentioned problem occurs is as follows.
This is because the conventional method does not include means for automatically activating the connection state of the network device to be connected.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a network monitoring device connection method for automatically activating a connection state of a network device to be connected. To provide.

FIG. 1 is a block diagram showing a main part of an embodiment of a network monitoring device connection system according to the present invention. In the embodiment of the present invention, an interrupt generating means (10 in FIG. 1) for generating an interrupt signal to the network monitoring device when the network device is connected.
Instruction holding means (11 in FIG. 1) for holding an instruction sequence necessary to activate the connection state; and interrupt detecting means (FIG. 1 in FIG. 1) for receiving an interrupt signal from the interrupt generating means (10 in FIG. 2). 20) and interrupt detection means (FIG. 1)
Loader means (21 in FIG. 1) which reads out an instruction sequence from the instruction holding means (11 in FIG. 1) in response to the instruction signal from (20).
And an instruction execution means (22 in FIG. 1) for executing the instruction sequence read from the instruction holding means (11 in FIG. 1) by the loader means (21 in FIG. 1). The network monitoring device updates the database for storing and managing the state of the network by executing the instruction sequence read from the instruction holding means (11 in FIG. 1) with the instruction execution device (22 in FIG. 1). Activate the connection.

An embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing the overall configuration of one embodiment of the present invention. With reference to FIG.
It comprises a network monitoring device 300, a package 100 on which a new network device 12 is mounted, a communication path 200 connecting them, a database 23 for holding the status of the network device, and an operator 400.

When connecting the package 100 on which the new network device 12 is mounted, the interrupt generator 10 mounted on the package generates an interrupt signal to notify the network monitoring device 300 of “connection”, It notifies the interrupt detection device 20 of the network monitoring device 300 on the system side.

The interrupt detecting device 20 that has detected the interrupt signal sends an instruction sequence read request signal to the loader device 21.

In response to the command sequence read request signal, the loader device 21 instructs the command sequence holding device 11 to transmit a command sequence via the communication path 200. The stored instruction sequence is transmitted via the communication path 200 and loaded into the instruction execution device 22 under the control of the loader device 21. When the transmission of the instruction sequence is completed, the instruction sequence holding device 11 sends an instruction sequence transmission completion signal to the loader device 21 via the communication path 200. In response, the loader device 21 issues an instruction to the instruction execution device 22, and the instruction execution device 22 executes the instruction sequence.

The instruction sequence transferred from the instruction sequence holding device 11 and executed by the instruction execution device 22 is transmitted to the network device 12.
The processing procedure required for activating the connection state of the first embodiment.

The instruction execution device 22 executes the instruction sequence, and updates the execution result to data that activates the connection state of the network device 12 stored in the database 23.

Finally, the operator 400 is notified that the connection state of the network device 12 has been activated.

Here, the instruction sequence holding device 11 stores an instruction sequence for realizing a data update process of the database 23 as, for example, a byte code sequence in the Java language. As for the Java language, for example, the literature (Ken Arnold, Ja
mes Gosling, “The JavaTM Programming Languag
e ", Addison-Wosley, 1996). In this case, the instruction execution device 22 receives the instruction sequence by receiving data called a bytecode sequence. I can receive it.
Further, the instruction execution device 22 executes Ja that executes the bytecode.
It can be realized with a virtual machine of va language.

As described above, according to the present invention,
This realizes a network monitoring device connection method that automatically activates the connection state of the network device to be connected.It saves labor when replacing or newly adding a package that mounts the network device, and reduces the connection time. This has the effect of significantly improving reliability and responsiveness.
