In a data transfer apparatus, a transferring destination information reader reads information of a transferring destination terminal associated with a primary destination terminal based on a communication quality request to the primary destination terminal received from a source terminal. A resource reservation instructor gives instructions for a communication resource reservation for purposes of a communication of the quality to the transferring destination terminal. A resource reserver determines whether or not a communication resource of the transferring destination terminal has been reserved based on the instructions by the resource reservation instructor, and responds a result of the determination thereof to the resource reservation instructor. Thereafter, the resource reservation instructor instructs the destination changer to change the primary destination terminal to the transferring destination terminal having reserved the communication resource when the resource reserver determines that the communication resource of the transferring destination terminal has been reserved, and the destination changer changes the primary destination terminal according to the instructions.
