Abstract: [Problem] A communication device is provided that enables one or more functions desired by a service user to act on a packet desired by the service user, in a service of forwarding packets in a network. [Solution] The communication device includes a communication unit configured to execute communication with another node and a control unit configured to control communication by the communication unit. The control unit generates path information to a target node. In the path information to the target node, at least information on at least one relay node present on a path to the target node and information on a function to be executed by the relay node are described.

Abstract: A communication device is provided that makes a single or a plurality of functions desired by a service user act on a packet desired by the service user in a service for transferring a packet in a network. A communication device is provided that includes a communication unit that communicates with another node and a control unit that controls the communication by the communication unit, in which the control unit generates path information with a target node, and in the path information with the target node, at least information regarding communication with at least a single relay node that exists between the communication device and the target node, information regarding a function to be performed by the relay node, and content of processing according to the function execution result by the relay node are written.
