ABSTRACT:
A packet transfer apparatus has a controller for controlling transmission of a PADO packet on the basis of the information that is previously set in the packet transfer apparatus in order that the PADO packet can be transmitted back to the terminals or a PADI can be discarded when the PADI packet sent from the terminals to the packet transfer apparatus does not have any Service-Name specified. In addition, another controller is used. This controller is provided so that, when a Service-Name that indicates the type of an offered communication service is specified in the PADI packet, it can judge whether the Service-Name is previously registered in a memory and decide to transmit the PADO packet to the terminal if the Service-Name is previously registered, but to discard the PADI packet if the Service-Name is not registered.
