FIG. 4 is a diagram showing a flow of processing in one embodiment of the terminal operation state management apparatus 102. 5 and 6 are examples of screens showing the terminal operation status displayed on the CRT display of the terminal operation status management device, and FIG. 6 is the detailed information of FIG.

Next, the operation of the embodiment shown in FIG. 1 will be described with reference to FIGS. 2, 3, 4, 5 and 6.

Before the hosts 111 and 112 connected to the packet switching network 101 start operation, a process 40
1, each element 30 of the terminal operation state management table 300
1 to 303 and 311 to 313 are initialized to “end”. The specified value of the terminal operation state management table 300 is “end”, and the host 111 and the terminal 1 that are not actually connected are
The value 303 of 23 is also “end”.

When the host 111 starts operation, the connected terminal becomes operable. When an opening message notifying the start of operation is transmitted from the terminal 121 to the host 111,
The host 111 uses the logical path 136 to notify the terminal operation state management apparatus 102 of the host name 201 of FIG.
The terminal 200 transmits a message 200 containing "1", the terminal name 202 as "terminal 121", and the state 203 as "operating". The terminal operation state management apparatus 102 determines the business end message 402 based on the content of the received message 200. , The element 301 of the terminal operation status management table 300 is set to “in operation” by the management table update processing 403. The terminal operation status management device 1
02 is, for example, green if all hosts are “finished”, red if there is at least one “failure”, and “yellow” otherwise, depending on the element of each terminal in the terminal operation status management table 300. ", Terminal names 501 to 503 are displayed on the CRT display as shown in FIG. When the operation of the terminal 121 is started, the character of the terminal 1 on the CRT display 500 changes from green to yellow, and the terminal operation state manager can recognize that the terminal 1 has started operation.

When the terminal 121 completes the operation for the host 111, a closing message notifying the completion of the operation is transmitted from the terminal 121 to the host 111, and the host 111 sends the terminal operation status management device 102 to the terminal operation status management device 102 by using the logical path 136. "Host 111" and terminal name 202
The terminal 200 transmits a message 200 containing “terminal 121” and the state 203 “completed”.

The terminal operation state management device 102
The management table updating process 403 is performed according to the content of 0, and the element 301 of the terminal operation status management table 300 is “finished”.
Replace with At this time, since the element 311 is also “end”, the display 501 of the terminal 1 on the CRT display changes from yellow to green by the screen display processing 404.

When a failure occurs in the line between the host 111 and the terminal 122 and the logical path 133 is disconnected, the failure notification from the packet switching network 101 or no response from the packet switching network 101 causes Is the terminal 12
2, and transmits a message 200 containing “Host 111” as the host name 201, “Terminal 122” as the terminal name 202, and “Fault” as the status 203 to the terminal operation state management device 102. I do. Terminal operation state management device 10
2 element 302 of the terminal operation state management table 300
Is rewritten to “failure” in the management table update processing 403 according to the content of the received message 200. One of the elements 302 and 312 of the terminal 2 in the terminal operation state management table 300
Since there is a “failure” in each case, the screen display processing 404
At the same time as the display 502 of the terminal 2 on the CRT display 500 turns red, an alarm notifies the operation manager of the occurrence of a failure.

The operation manager operates the CRT display 500.
By inputting “terminal 2” in the above detailed information 504, the detailed information screen 600 can be opened. If both the host 1 and the host 2 are displayed as faults, the operation manager can determine that the terminal or the line between the packet switching network 101 and the terminal 122 is faulty, and the host 1 is operating and the host 2 is faulty. If it is displayed, it can be determined that the failure is in the logical path 133.

When the status of the terminal changes, the terminal operation information message 200 is transmitted from each host to the terminal operation status management device 1.
02, the host transmits a business end message to the terminal operation state management device 102 at the end of the business.

When the terminal operation state management apparatus 102 receives the business end message from all the hosts, it goes through the business end message judgment processing 402 and ends the processing by the all-host business end judgment processing 405.
