BAND ALLOCATING METHOD

摘要

Upon measuring a packet round trip time RTT from a source device (10) to a sink device (30), the source device (10) requests a band management unit (37) of a network to allocate bands for round trip packets. The band management unit (37) notifies a reservation period Tsource for transmitting a packet from the source device (10) to the sink device (30) and a reservation period Tsink for sending back a packet from the sink device (30) to the source device (10), using a beacon signal. The reservation period Tsource is allocated within a time period starting from a middle timing of a time cycle Tbeacon of the beacon signal, and the reservation period Tsink is allocated at a middle timing between the reservation period Tsource and the beacon signal right after the reservation period Tsource.
