摘要： PROBLEM TO BE SOLVED: To simplify a configuration and perform fair band allocation of uplink signals for respective user terminals in a network system which concentrates the uplink signals from the respective user terminals to an upper network in a plurality of stages.SOLUTION: A band allocation method makes an upper limit of a band allocated to each ONU 3 be smaller as a storage amount of uplink signals in an output buffer 13 of a line concentration switch 1 is larger; and sets the upper limit of the band allocated to each ONU 3 to be the same for all ONUs 3 belonging to the line concentration switch 1. The band allocation method performs setting so that a band allocated to an ONU 3 is small even if the ONU 3 has a large transmission request amount, when uplink signal congestion occurs; and performs setting so that a band allocated to an ONU 3 can be large if the ONU 3 has a large transmission request amount, when the uplink signal congestion does not occur. Thereby, fair band allocation of uplink signals for respective user terminals 4 can be implemented.
