<P>PROBLEM TO BE SOLVED: To improve data transmission efficiency and shorten a DBA calculation time. <P>SOLUTION: The dynamic band allocation method comprises: an ONU grouping step in which ONUs among the ONUs connected to a multiplexing light transmission path in a linkup connection state are divided into a plurality of groups to divide the ONUs into the ones where an NSR-DBA is applied and the ones where an SR-DBA is applied; a fixed band allocation step in which a fixed band is allocated to the ONUs belonging to a group where the NSR-DBA is applied; and a best effort band allocation step in which a best effort band is allocated based on SR-DBA calculation to the ONUs belonging to a group where the SR-DBA is applied. <P>COPYRIGHT: (C)2012,JPO&INPIT |
