Resum
Long-Reach (LR) extension is a promising scenario for the future next generation access networks, enabling less Central Offices (COs) in the field and a large number of customers in the access/metro area. Because of the large propagation time between OLT and ONUs, inefficiency occurs in the Dynamic Bandwidth Allocation (DBA) upstream protocols. To solve this drawback, a new efficient DBA protocol, named GPON Redundancy Eraser Algorithm for Long-Reach (GREAL), is proposed, removing the redundancy...
