Local-traffic-redirection-based dynamic bandwidth assignment scheme for EPON with active forwarding remote repeater node

Abstract

The Ethernet passive optical network (EPON) has been considered as one of the most suitable next-generation optical access solutions. As a time-division multiplexing PON (TDM-PON) technology, the transmission media of EPON is shared among multiple users. Therefore, medium access control (MAC) protocol plays an important role in enabling a dynamic bandwidth assignment (DBA) mechanism that provides efficient and fair utilization of the PON resources. However, the DBA mechanism implemented in products is open for vendor customization. In this paper, we propose a novel local-traffic-prediction-based dynamic bandwidth assignment (LT-DBA) mechanism applicable in a remote-repeater-based EPON system..
