A multi-OLTs and virtual passive optical network for hybrid network

Passive optical network (PON) has been widely applied in access network benefitting from its large bandwidth and low-cost passive components that consumes less power, and transport different type of services in hybrid networks. In this paper, we propose a multi-OLT-based virtual PON (MV-PON) system with a dynamic bandwidth allocation (DBA) algorithm. According to simulation results, the proposed system effectively reduces the complexity for data packet processing in the OLT of multiple services.
