In a communication apparatus performing data communication through a network having a relay apparatus which relays data, a data-path establishment unit establishes a data-communication path between the communication apparatus and an opposite end of the data-communication path, and a control-path establishment unit establishes a control-information path between the communication apparatus and an opposite end of the control-information path, where the control-information path is arranged for transmitting control information for controlling the data communication through the control-information path. In addition, an instruction transmission unit transmits an address-set instruction instructing the relay apparatus to search for a next-hop node in the data-communication path and store a MAC address of the next-hop node before the control-information path is established by the control-path establishment unit.
