Beschreibung
Zusammenfassung:	A network system comprises a first communication device having a first address connected, using a network, to a second communication device having a second address. The first communication device includes a monitor frame transmitter configured to generate a monitor frame including the second address as a destination address and the first address as a source address, and to output the generated monitor frame to the network; and a monitoring-response frame monitor configured to monitor reception of a monitoring-response frame sent back from the second communication device. The second communication device includes: a monitoring-response frame transmitter configured to, in response to reception of the monitor frame, generate the monitoring-response frame by exchanging the destination address in the received monitor frame for a source address and the source address in the received monitor frame for a destination address, and output the generated monitoring-response frame to the network.
