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.

A dynamic bandwidth allocation (DBA) method comprising:
- 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, respectively, and a plurality of current valid-data ratios corresponding to the plurality of transmission containers, respectively, to determine a plurality of next bandwidths that are allocated to the plurality of transmission containers, respectively.
An optical line terminal (OLT) comprising:
- a receiver circuit, wherein within an available upstream bandwidth of the OLT, the receiver circuit is configured to receive 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
- a processor, configured to perform dynamic bandwidth allocation (DBA), wherein the processor is configured to refer to a plurality of current dynamic bandwidth report unit (dbru) values corresponding to the plurality of transmission containers, respectively, and a plurality of current valid-data ratios corresponding to the plurality of respectively, determine a transmission containers, transmission containers, respectively, to determine a plurality of next bandwidths that are allocated to the plurality of transmission containers, respectively.
