Application of a multi-OLT PON system and its dynamic bandwidth allocation algorithm

Fahmida Rawshan, MinChul Ju, Youngil Park

Abstract

We propose a novel cost-effective architecture of passive optical network (PON), which can support multiple optical line terminals (OLTs). We also propose Guaranteed Limited Dynamic Bandwidth Allocation (GLDBA) scheme for flexibly managing downstream bandwidth among multiple OLTs. For upstream transmission in the proposed multi-OLT PON system, we modify Limited Dynamic Bandwidth Allocation (LDBA) scheme of the existing EPON. Performance analysis shows that the PON architecture can successfully provide services from multiple service providers to access area. The network can also provide an alternative protection path in case of network failure between an OLT and Remote Node (RN).
