Abstract:
1. A message transfer apparatus comprising: a first port to be connected to a first network to which a communication terminal is connected; a second port to be connected to a second network; a message processor that transfers a message received by the first port to the second port, and transfers a message received by the second port to the first port; a Quality of Service (QoS) terminal detector that determines whether first specific information capable of specifying a message type is included in the received message, and when the first specific information is included therein, detects the communication terminal, the communication terminal being a sender of the message received by the first port or a destination of the message received by the second port, as a QoS terminal requesting application of QoS; a storage unit that stores a connection condition that indicates a condition of a connection form to the first port of the QoS terminal and the communication terminal that is not requesting application of a QoS; and an output controller that determines whether the QoS terminal satisfies the connection condition, and when the QoS terminal does not satisfy the connection condition, controls output of output information indicating that the connection condition is not satisfied.
