1. A communication device which operates as an application node which executes one or a plurality of applications, the device comprising:
a communication circuit that executes communication with a plurality of other logical nodes; and
a control circuit that controls the communication by the communication circuit, wherein
the plurality of other logical nodes are logical nodes which are applied with application function chaining (AFC) in which, when transmitting or receiving an application message having the application node as a transmission source or a transmission destination, respectively, one or a plurality of application functions in each of the plurality of other logical nodes act on the application message midway along corresponding transmission paths or reception paths of the application message through the plurality of other logical nodes, and
the control circuit causes the communication circuit to transmit, to each of the plurality of other logical nodes, an AFC designation message according to a publishing/subscription model in order for the plurality of other logical nodes to respectively transmit or receive the application message to or from the application node,
wherein the AFC designation message designates a type of AFC to be used by the plurality of other logical nodes, and
wherein the publishing/subscription model indicates to the plurality of other logical nodes whether the application node is on an ingress side or an egress side of the plurality of other logical nodes.
