When the device to be used is the device of the other computer 20, the device management information is added to the input / output information and the control is passed to the transmission / reception management unit 16.

The device allocation management unit 15 includes an input / output control unit 13
It is checked whether the device requested to be used by the device exists in the device management file 11 and the result is input / output control unit 1
3 and a function of registering the entered device allocation information in the device management file 11.

The transmission / reception management unit 16 establishes a session with a computer in which an actual allocation device exists, and the input / output control unit 1
The function of transmitting the device management information and the input / output information sent from the other computer 3 to the other computer 20, and the response from the other computer 20 is monitored by the timer, and when the time is over, the error information is passed to the input / output control unit and displayed. It has a display function.

The transmission / reception starting unit 21 has the following functions. A function of establishing a session with the computer 10 that makes an input / output request to the real allocation device 25 and receiving the device management information and the input / output information from the computer 10 as the request source. A function of passing the received information to the input / output unit 24. A function of receiving the input / output result from the real allocation device 25 by the input / output unit 24 and transmitting the result to the requesting computer 10. A function of passing the reception information to the device allocation unit 22 at the time of initial device allocation. A function of receiving the result from the device initial unit 23 and transmitting it to the requesting computer 10.

The device allocation unit 22 is activated by the transmission / reception activation unit 21 at the time of initial device allocation, receives device management information,
Based on the information, it has a function of allocating an actual device 25 and activating the device initial part 23.

The device initializing unit 23 has a function of initializing the device 25 allocated by the device allocating unit 22 and a function of passing the result to the transmission / reception starting unit 21.

The input / output unit 24 receives the device management information and the input / output information from the transmission / reception starting unit 21, and receives the actual device 2
5 has a function of performing input / output according to a request and a function of passing the result to the transmission / reception starting unit 21.

FIG. 2 is a flowchart when allocating an initial device. The name of the computer 20 having the device to be allocated from the keyboard 14, the name of the device 25 to be allocated, its capacity,
Input allocation information such as type and virtual device name (step 31). 4 ^ 5: The allocation management unit 15 registers the allocation information in the device management file 11. Next, the transmission / reception management unit 16 transmits the allocation information to the computer 20 in which the allocation device exists (step 32).

In the computer 20, the requesting computer 1
The transmission / reception activation unit 21 receives the device allocation information from 0 (step 33). The transmission / reception activation unit 21 activates the device allocation unit 21 (step 34). The device allocation unit 21 allocates the actual device 25 based on the device allocation information (step 35). Next, the device initial unit 23 sends the assigned device 2
5 is initialized (step 36). The transmission / reception activation unit 21 transmits the allocation and initialization results to the requesting computer 10 (step 37), the transmission / reception management unit 16 receives the end result (step 38), and displays the end result on the display 12 ( Step 39).

FIG. 3 is a flowchart showing the operation when the device 25 of the other computer 20 is used. From the keyboard 14, a virtual device name to be used from now on is input. The device allocation management unit 15 inputs the device allocation information for the virtual device name from the device management file 11 (step 4).
1).

Normally, an application program or the like is started and an input / output request is made to the device, in the same manner as an application program or the like that uses the device is started (step 42).

The device allocation management unit 15 includes an input / output control unit 13
It is checked whether the input / output request from the virtual device is an input / output to the virtual device (step 43). When the input / output is not to the virtual device, the input / output is performed from the device of the own computer 10 as usual, and the input / output control unit 13 notifies the application program or the like of the result (step 4).
4). If the request is an input / output request to a virtual device, the transmission / reception management unit 16 transmits the device allocation information and the input / output information from the device management unit to another computer (step 45).

In the computer 20, the transmission / reception starting unit 21
Receives the device allocation information and the input / output information from the requesting computer 10 (step 46). The input / output unit 24 performs input / output according to the request from the actual device based on the device allocation information and the input / output information (step 47). The transmission / reception activation unit 21 transmits the input / output result from the input / output unit 24 to the requesting computer 10 (step 48).

In the computer 10, the transmission / reception management unit 16
Receives the input / output result (step 49), and the input / output control unit 13 notifies the input / output result to the application program or the like (step 50). As a result, a normal application process is performed (step 5).
1).
