Long-Reach (LR) extension is a promising scheme for 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 ONUs and OLT, inefficiency occurs in the Dynamic Bandwidth Allocation (DBA) protocols. To solve this drawback the GPON Redundancy Eraser Algorithm for Long-Reach (GREAL) is proposed, removing the redundancy caused by scheduling intervals (SIs) smaller than the Round-Trip-Time (RTT), while providing also multi-service QoS. This algorithm is independent of the SIs and uses real data queuing information without prediction, achieving a great enhancement in bandwidth utilization.
