Abstract

PURPOSE:To arrange a local terminal for maintenance in respective nodes by providing an interface converting processing at the local terminal provided at the node of a data packet network. CONSTITUTION:A command inputted from a local terminal is sent from a terminal input output processing 11 to a command control 12. A command control 12 sends only the address, in which the address of the command is in the self- node, to a command adapter 13. The adapter 13 edits the data to transfer to a command execution program 14 concerning the command in which a parameter is normal and delivers the data to a program 14. Thereafter, in the condition to become the result or a response waiting shut-off returned from the program 14, the adapter 13 edits the data and message to respond to the command control 12 and executes the output request to the command control 12. Thus, the command control 12 outputs the message through a terminal input output processing 11 to a terminal picture.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a maintenance command execution processing method, and more particularly to a maintenance command execution processing method that is controlled from a local terminal within a node.

[Conventional technology]

Conventionally, failures occurring within a node have been repaired by issuing maintenance commands from a network management operation device (remote terminal) connected via a general communication line within the node. At this time, since the remote terminal and the command execution program in each node are connected via a general communication line, the input command format is transmitted as is in characters (ASCII code) to improve transmission efficiency on the communication line. Instead, it was controlled by an interface (referred to as a communication interface) in which each piece of information was compressed into binary numbers.

[Problem to be solved by the invention]

The above-mentioned method of issuing maintenance commands from a remote terminal when a failure occurs within a node can only be controlled from a remote terminal connected to each node via a communication line. However, each node must be dealt with individually, and it also has the disadvantage that it becomes uncontrollable when there is a failure in the communication line. Furthermore, if each node has a local terminal that can be executed independently, there is a drawback that it cannot be directly interfaced with an existing command execution program (created with a communication interface).

SUMMARY OF THE INVENTION An object of the present invention is to provide a maintenance command execution processing method that improves the above-mentioned drawbacks by providing an interface conversion process in a local terminal.

[Means to solve the problem]

The maintenance command execution processing method of the present invention includes a command input/output control program that inputs maintenance commands and outputs the execution results of the maintenance commands in a local terminal provided in a node of a data packet network; and a command adapter program that mutually converts the respective interfaces of the command input/output control program and the command execution program.

〔Example〕

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

FIG. 1 is a flowchart showing one embodiment of the present invention, and FIG. 2 is a flowchart of command adapter processing. In the figure, the command input from the local terminal is the terminal input/output processing 11 (
TTY-IOC 3) to the command control 12.

The command control 12 determines whether the destination of the command is within its own node, and treats a command that is not within its own node as an error.

Next, the command is passed to the command adapter 13, and the input parameters are analyzed <21).The command adapter 13 edits the data passed to the command execution program for commands with normal parameters (conversion from IOCS interface to communication interface). ) is performed (22
), commands with abnormal parameters are treated as errors. Next, it is determined whether or not there will be a conflict due to factors such as the command being currently being executed (23). As a result of the determination, if no conflict occurs, the edited data is delivered to the command execution program 14, and execution is requested and a response is waited for at the same time (24).

After that, the command adapter 13 edits the data and message (converts from the communication interface to the ROCS interface) to respond to the command control 12 regarding the result returned from the command execution program 14 or the state where the response is waiting (25). , 26), makes an output request to the command control 12, and the command control 12
outputs the message to the terminal screen through terminal input/output processing (11).

〔Effect of the invention〕

As explained above, the present invention makes it possible to install a local terminal for maintenance in each node, and uses TT for command adapter processing.
By also providing a conversion function between the Y-IQCS interface and the communication interface, there is an effect that existing command execution programs can be used.
