In step S163, the traffic amount determination units 244, 254, 264, 274 of the device cards 24 to 27 on the transmission side determine whether or not a predetermined time has elapsed after the transmission in step S161. The process returns to step S162.
In step S164, if the predetermined time has elapsed, it is determined that the traffic amount determination units 244, 254, 264, 274 of the device cards 24 to 27 on the receiving side have decided to interrupt the frame transmission, and the processing ends. To do.
[0068]
FIG. 17 is a flowchart for explaining an operation example of the update control unit 281 of the control card 28 when traffic occurs.
In step S171, the update control unit 281 of the control card 28 determines that each of the traffic amount determination units 244, 254, 264, and 274 of the device cards 24 to 27 on the receiving side receives the transfer of update data, thereby receiving the device cards 24-27. It is determined whether or not there is a notification that a traffic volume exceeding the processing capacity has occurred. If there is no notification, the processing is terminated.
[0069]
If there is the notification in step S172, the update control unit 281 requests the switch card 23 to disconnect the current device card.
In step S173, with reference to the transfer order setting unit 282, the connection request between the reverse adjacent device cards is made to the switch card 23, the transfer is performed first, and the process is terminated.

In step S181, when the traffic volume exceeds the processing capacity, the update control unit 281 requests the switch card 23 to maintain the disconnection between the device cards.
[0071]
In step S182, it is determined whether or not a notification below the traffic amount processing capability has been received from the corresponding traffic determination unit. If not, the process ends.
In step S183, if a notification below the traffic processing capacity is received, it is determined whether a storage system file storage completion notification has been received with the reversely-adjacent device card that has been transferred first, and this notification is sent If not, the process ends.
[0072]
In step S184, when the notification is received, a request for resuming connection between the interrupted device cards is made to the switch card 23, and the transfer is resumed. FIG. 19 is a sequence diagram for explaining the operation of the transmission / reception units 243, 253, 263, and 273 in FIG. 1 in which the traffic amount is suspended and resumed depending on the processing capability with respect to the transfer order example in FIG. .
[0073]
As shown in the figure, the transmission / reception unit 243 of the device card 24 receives the update system file from the file server 1.
Further, the transmission / reception unit 243 transmits the first frame of the update system file to the transmission / reception unit 253 of the device card 25.
The transmitted first frame is accumulated in the frame buffer 250, and the accumulated data of the first frame is stored in the temporary memory 251.
[0074]
If the transmission / reception unit 243 does not receive a transmission request from the transmission / reception unit 253 of the device card 25 within a predetermined time, the transmission / reception unit 243 interrupts transmission after the second frame to the transmission / reception unit 253 and reverses the first frame of the update system file. The data is transmitted to the transmission / reception unit 273 of the adjacent device card 27, the transmission request is received from the transmission / reception unit 273, the second frame is transmitted to the transmission / reception unit 273, and so on.
[0075]
The transmitted first frame, second frame data,... Are sequentially accumulated in the frame buffer 270, and the accumulated first frame, second frame,... Are stored in the temporary memory 271. When the data of all frames is stored, the transmission / reception unit 243 receives from the transmission / reception unit 273 a storage system 273 storage update notification from the frame buffer 270 to the temporary memory 271.
[0076]
Furthermore, after the above completion notification, when the transmission / reception unit 243 receives a transmission request from the transmission / reception unit 253 of the device card, the transmission / reception unit 243 and the transmission / reception unit 273 send the second frame and the first frame of the update system file. The transmission request is transmitted to the transmission / reception unit 253 of the device card 25 and the transmission / reception unit 263 of the device card 26, the transmission request is received from the transmission / reception unit 253 and the transmission / reception unit 263, and the third frame and the second frame are transmitted to the transmission / reception unit 273 and the transmission / reception unit 263. Each is transmitted, and this process is repeated.
[0077]
The transmitted first frame data, second frame data,... Are sequentially accumulated in the frame buffer 260, and the accumulated first frame, second frame,... Data are stored in the temporary memory 261. When the data of all the frames is stored, the transmission / reception unit 273 receives from the transmission / reception unit 263 a storage completion notification of the update system file from the frame buffer 260 to the temporary memory 261.
[0078]
Also, the transmitted second frame, third frame data,... Are sequentially accumulated in the frame buffer 250, and the accumulated second frame, third frame,... Data are stored in the temporary memory 251. When all frame data is stored, the transmission / reception unit 243 receives from the transmission / reception unit 253 a storage completion notification of the update system file from the frame buffer 250 to the temporary memory 251.
[0079]
Therefore, according to the present invention, even if the amount of traffic in the apparatus suddenly increases during the file update, the update system file is efficiently transferred to the adjacent device card first, and the file update is interrupted, or Since it is now possible to easily perform processing such as reducing the file transfer amount of the update system file, the amount of traffic in the device is taken into account when updating the file of the device installed in the device in operation Efficient file transfer is now possible.
