Dynamic bandwidth allocation method and optical line terminal

Abstract

A dynamic bandwidth allocation method includes: within an available upstream bandwidth of an optical line terminal (OLT), receiving an upstream frame that is sent via a plurality of transmission containers with a plurality of current bandwidths allocated thereto in a time division multiple access (TDMA) manner; and referring to a plurality of current dynamic bandwidth report unit (dbru) values corresponding to the plurality of transmission containers and a plurality of current valid-data ratios corresponding to the plurality of transmission containers to determine a plurality of next bandwidths that are allocated to the plurality of transmission containers.
