摘要： An allocation determining unit determines a bandwidth allocation for each of a plurality of subscriber devices in each data-collection cycle. A history managing unit takes a history of a request increment from a bandwidth request amount acquired from more than one time of data collections and an allocation amount allocated by the allocation determining unit for the bandwidth request amount, and presents a bandwidth request amount for the allocation determination to the allocation determining unit by dividing the bandwidth request amount into a plurality of request increments indicated by the history.

摘要： In a PON system, clocks of an optical network unit and an optical line terminal are synchronized. An optical network unit generates a new encryption key and transmits it to an optical line terminal. The optical network unit transmits a notification that includes an encryption key changing time to the optical line terminal. Finally, the optical network unit and the optical line terminal change previously held encryption keys to the new encryption key at the encryption key changing time.

摘要： An optical communication system connects one to a plurality subscriber-side apparatuses having one to a plurality of subscriber terminals and a station-side apparatus that covers the subscriber-side apparatuses with an optical transmission medium, sets one to a plurality of logical links between the station-side apparatus and each subscriber-side apparatus, and performs a data transfer with an MAC frame using a set logical link. The station-side apparatus and the subscriber-side apparatus transmit control information of a plurality of set logical links by storing the control information in a single MAC frame.
