With the above-described device, as illustrated in FIG.
For example, b-1 of file 1 between the terminal device 14-1 and the TC
When the file transfer is notified from the terminal device 14-2 while the part is being transferred, the state of the file being transferred is stored in the file control memory.
11, the contents b-2 and b-3 of the file data being transferred to the terminal device 14-1 are saved in the terminal control memory 13, and then the file is transferred to the terminal device 14-2. When the next data being transferred is requested from the terminal device 14-1,
By restoring the state of the file being transferred from the file control memory 11 and restoring the file data b-2 and b-3 in the middle of the file transfer from the terminal control memory 13 to the terminal device 14-1, the file transfer from the previous continuation is performed. It can be performed.

〔Example〕

The processing steps of the file transfer apparatus as one embodiment of the present invention are shown in order from FIG. 3 to FIG.

The system of this embodiment includes a host computer (not shown), a terminal controller (TC), and a plurality of workstations WS, each of which has a disk storage device for storing files. The TC further includes a file control memory 11, a file transfer means 12, and a terminal control memory 13, and each terminal control memory includes
(14-1,14-2, ..., 14-n)
Is assigned.

The files 1, 2,... Are stored in the disk storage device of the TC. File 1 is divided into a, b, c, etc.
a, b, c, etc. are further divided into areas such as 1, 2, 3,.
This delimiter is, for example, in a unit of about 300 to 4000 bytes, and an optimal area is selected in terms of processing capacity in a system, relation with a program, and the like. Each WS includes a file transfer means. The files in the disk storage device provided for each WS are file F1, file
It is called F2 etc.

First, a description will be given with reference to FIG. In the process of FIG. 3, there is shown a case where the areas 1, 2, and 3 of the section a of the file 1 are transferred between the TC and the WS 14-1 as the terminal device and stored in the file F1. The data from the file 1 is transferred to the file transfer unit A of the WS 14-1 via the file transfer unit 12 of the TC, and is stored in the file F1 from the file transfer unit A.

The above transfer ends area 3 of section a and area 1 of section b
FIG. 4 shows a state in which the process has proceeded to.

Normal file transfer is performed on a file-by-file basis, and transfers from the beginning to the end of data in a file. Therefore, the first file transfer request from each WS to each file is made from a of file 1 and d of file 2. The file transfer request after the transfer is temporarily interrupted is performed from the data transfer immediately after the interruption, such as b-2 of file 1 or e of file 2.

Accordingly, FIG. 5 and subsequent figures show the processing steps when a transfer request for the file 2 is issued from the WS 14-2 during the transfer of the data in the area b-1 of the file 1.

In the process of FIG. 5, the access information of the file 1 is stored in the file control memory 11, and the information from the WS 14-1 and the data of the areas b-2 and b-3 of the file 1 are stored in the terminal control memory 13. Evacuate to the part.

In the process shown in FIG. 6, the data in the e section of the TC file 2 is transferred to the file F2 of the WS 14-2. File 2
The data of e-1, e-2, and e-3 are transferred to the file transfer means B of the WS 14-2 via the file transfer means 12, and further transferred from the file transfer means B to the file F2.

In the process of FIG. 7, the WS in the process of FIG.
The untransferred portions b-2 and b-3 of the file of the file 1 are transferred to the file F1 of the WS 14-1 based on the file transfer request from 14-1 again. That is, the data saved in the terminal control memory 13 is read out, and the file
Is transferred to the file transfer means A via the file transfer means A, and is stored in the file F1 from the file transfer means A. These file transfer means include a program for performing file transfer between the TC and the WS, and the file transfer is executed.

Through the processes shown in FIGS. 3 to 7 described above, the transfer between one WS and the TC interrupts the transfer between the other WS and the TC in a time-division manner with a certain data break. And another transfer process can be performed before the end of the transfer between one WS and TC. According to this, it is possible to further improve the processing capacity by utilizing an idle time or the like occurring between transfer data areas caused by a limit of the transfer processing capacity in the system.

〔The invention's effect〕

By transferring the same file or a different file to a plurality of terminal devices in a time-division manner at a predetermined break in the transfer data, the file transfer time can be reduced.

In addition, data during file transfer is saved in the terminal control memory, so immediately after the file transfer with another WS is started, immediately after the file transfer is resumed, the terminal control memory is not accessed without accessing the disk. Data transfer can be performed. For this reason, the number of accesses to the disk is reduced, and the performance is improved.
