Bandwidth allocation method, optical line terminator, subscriber station, communication system, and recording medium recording program of device

A subscriber station comprising:

• an allocating unit that determines 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 to which a plurality of subscriber stations are connected through an optical network base unit, the optical line terminator comprising

• a pipeline transmitting unit that transmits bandwidth allocation information transmitted from the subscriber stations to all subscriber stations to be allocated with bandwidth.

A recording medium recording a program of a subscriber station, the program causing a computer of the subscriber station 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.
