摘要： Provided is a communication system which is provided with a plurality of communication devices and transfers a packet between the plurality of communication devices through a communication path. When a packet is looped back at any of the communication devices on the communication path to verify connectivity of the communication path, a first communication device of the plurality of communication devices stores, in a first region of header information of the packet, first information for designating the communication device at which the packet is looped back, further stores, in a second region of the header information of the packet, second information on a loopback point in the designated communication device at which the packet is looped back, and sends the packet to which the first information and the second information have been added.
