ABSTRACT

            Optical access networks are evolving as the next generation access networks for the broadband services, which provides higher data rates. Passive Optical Networks (PON) have emerged as a promising solution for the optical access networks due to cost efficient passive components. To provide good network access to the users a PON system must employ an efficient bandwidth allocation algorithm, which allocates the available bandwidth dynamically to the users. This paper describes the architecture, upstream operation, downstream operation and various DBA Algorithms proposed for the PON networks.

Keywords: Optical Fibre, PON, Dynamic Bandwidth Allocation (DBA), OLT, ONU.
