Abstract
A control apparatus executes configuration processing that includes applying filters for blocking input and output of a test packet to ports associated with the packet forwarding devices, except for one or more ports on an assumed forwarding route in a section targeted for a forwarding status determination and configuring the packet forwarding device located at an end port of the section so that the test packet that arrives at the end port is forwarded to the control apparatus, executes communication processing that includes transmitting the test packet from the communication circuit to a start port of the section, and executes determination processing that includes determining that packet forwarding is performed normally in the section, upon receipt of the test packet via the communication circuit after the transmission of the test packet.
