Abstract:
1. A bandwidth allocation method comprising: an allocating step for an optical network unit to determine bandwidth allocation based on a predetermined allocation condition; a bandwidth transmitting step for the optical network unit to transmit bandwidth allocation information determined in the allocating step to an optical line terminator; and a pipeline transmitting step for the optical line terminator to transmit the bandwidth allocation information transmitted from the optical network unit to all optical network units to be allocated with bandwidth, wherein the optical network unit transmits the bandwidth allocation information along with transmission data in the allocated bandwidth to an optical line terminator, bandwidth allocation in a next service cycle is determined during a service cycle in which data transmissions by all optical network units to be allocated with bandwidth are performed, and in the optical network units to be allocated with bandwidth, an order for setting the optical network unit in which the bandwidth allocation is determined in the allocating step is sequentially shifted in each service cycle.
