Network communication confirmation device, network communication confirmation method, and network communication confirmation program

摘要

Even when the number of bases to be monitored increases, the system is prevented from becoming complicated and the occurrence of software failure on the system is prevented. A communication confirmation device connected to one or more segments via a computer bus network, for at least one segment included in the one or more segments, one or more operation nodes included in the segment and the communication confirmation device; Communication with the operation node as a transmission destination, whether communication is established between the downstream bridge provided in the segment including the operation node and the upstream bridge provided in the communication check device. Whether or not communication is established between the confirmation packet and the communication confirmation response packet which is a response packet to the confirmation packet and the upstream bridge provided in the communication confirmation device and the downstream bridge provided in the segment including the operation node. Confirm using the packet to send and receive.
