A master station sends polling signals to each slave station with respect to CBR data to which required constant bandwidth has been allocated. Next, the master station sends polling signals to each slave station with respect to VBR data with its average bandwidth kept constant. Finally the master station sends polling signals to ABR data to which residual bandwidth has been allocated. The bandwidth of a frame is allocated to a plurality of data from higher to lower priority order. Therefore excellent traffic characteristics can be obtained even when a plurality of data of different traffic characteristics are mixed in the system. <IMAGE> |
