Abstract
A communication system and method comprising a higher-network apparatus and a lower-network apparatus connected through a PON system, which transfers uplink data from the lower-network apparatus to the higher-network apparatus at high speed so as to meet severe conditions required for a delay time between the higher-network apparatus and the lower-network apparatus. The method including a scheduling execution process in which a higher-network apparatus performs scheduling for uplink communication from each of the lower-network apparatus to the device itself and an uplink data transmission permission process in which the higher-network apparatus calculates a transmission time and a transmission permission amount of uplink data transmitted from an ONU to OLT based on the scheduling for uplink communication and notifies the OLT.
