A DBA ALGORITHM AND EQUIPMENT SUPPORTING FAIRNESS FOR EPON

摘要

The present invention relates to a dynamic bandwidth allocation method and apparatus in which all ONUs can be equally allocated an uplink bandwidth in an Ethernet-PON. Status information of each priority queue is transmitted to the OLT using a REPORT message, and the OLT calculates an uplink bandwidth to be allocated to the ONU by the dynamic band allocation algorithm based on the OLT. And including the TIMESLOT calculated by the dynamic band allocation algorithm in the GATE message information including the GRANT to the ONUs, and transmitting the information according to the assigned TIMESLOT information. According to the present invention, there is an effect that data can be transmitted more efficiently than the conventional method in which Ethernet-PON does not support fairness.
