パケットを配布するからである。Next, the operation will be explained with reference to the flow diagrams of FIGS. 3 and 4. First, the management device 8 transfers the management information of the information transmission control devices 2, 4, .
Distributed on 6th. In this case, press the button and the information transmission control device 2
．． When any of the management information such as the status in 4.6 changes, each time the management information changes, the management device 8 collects and updates the management information, and distributes it to all information transmission control devices 2 and 4.6 (step STI). . This management information also includes a definition bit indicating the presence or absence of a transmission definition for periodically updated information transmission. Next, when the management device 8 has finished distributing the management information, the management device 8 selects the information transmission control device 2 with the smaller address on the information transmission path 1 and whose status is normal, and and transmits a control packet (step ST2). Furthermore, it waits for a response packet from the information transmission control device 2 to this control packet, and sets a monitoring timer in the management device 8. Here, it is checked whether or not a response packet has been received within the set time (step ST3).
, the management device 8 resets the supervision timer (step ST4), and does not participate in this transmission process until it receives the control packet again (step ST5). On the other hand, if the response packet is not received within the set time, the management device 8 considers the transmission control device 2 to be abnormal and sends the next lowest address in the management information.
Moreover, it selects an information transmission control device 4 with a normal status and transmits a control packet to this information transmission control device 4 (STESOBU ST2). Thereafter, in the same way as for the information transmission control device 2, the response packet monitoring timer is set. Furthermore, even if the management device 8 becomes abnormal, the control packets are returned to the normal information transmission control device [2.4.6].
Since each information transmission control device fif2, 4.6
processes the control packet and its response packet using the same procedure as that performed by the management device 8. Note that if a predetermined information transmission control device is deemed to be abnormal due to the timeout of the monitoring timer, the management information must not be modified. This is because the management information is managed by the management device 8, and the management device 8 distributes control packets to all information transmission control devices 2.4.6.

１５）。On the other hand, when the information transmission control device 2.4.6 receives management information from the management device 8 (step STII) and receives a control packet (step ST12), it always sends a response packet to the source of the packet. (Step ST
13). Next, while retaining the control packet data, the transmission information in the storage area of each computer 3.5.7 connected via the local bus is transmitted without requiring a startup command for these computers 3.5.7. Retrieval (step ST14),

6 selects the transmission destination of the next held control packet based on the above management information (step ST16), and transmits this control packet. Then, a monitoring timer is set (step ST17). Furthermore, it is determined whether or not a response packet has been received within the monitoring timer time (step ST
18), if received, reset the monitoring timer (
Step ST19), the process ends. On the other hand, if no reception is received, it is checked whether the monitoring timer has timed out (step ST20), and if the timeout has occurred, the processes from step 16 onwards are repeatedly executed, and when the timeout has not been received, the processes from step 18 onwards are repeated. I'll have to return it.

It has the same effect as the example.

There is an effect that you can get by continuing without letting it happen.
