Bandwidth allocation method, optical line terminator, optical network unit, communication system, and recording medium recording program of device

An optical network unit comprising:

• an allocating unit that allocates bandwidth allocation based on a predetermined allocation condition;
• and
• a bandwidth transmitting unit that transmits bandwidth allocation information determined by the allocating unit to an optical line terminator.

An optical line terminator connected to a plurality of optical network units, the optical line terminator comprising

• a pipeline transmitting unit that transmits bandwidth allocation information transmitted from the optical network units to all optical network units to be allocated with bandwidth.

A recording medium recording a program of an optical network unit, the program causing a computer of the optical network to execute:

• an allocation process of determining bandwidth allocation based on a predetermined allocation condition;
• and
• a bandwidth transmission process of transmitting bandwidth allocation information determined in the allocation process to an optical line terminator.
