Communication device and method, and recording medium
First Claim
1. A communication device comprising:
- a selection unit which selects one of a relay protocol designed to transmit the communication data to a receiving-side communication device via a control station, and a direct protocol designed to directly transmit the communication data to the receiving-side communication device, in accordance with a condition that defines a state wherein a total communication bandwidth used to transmit the communication data does not exceed an allowable communication bandwidth and is used to switch a protocol between the relay and direct protocols; and
an interface unit which transmits the communication data in accordance with the protocol selected by the selection unit.
