Abstract
The Ethernet Passive Optical Network (EPON) has been
considered as one of the most promising candidates for the nextgeneration
optical access solutions. In EPON, which is also
referred as the Time-Division-Multiplexed PON, upstream fibre
is shared among multiple users in a timely manner. Therefore,
bandwidth allocation is a challenging and critical issue which
needs to be addressed efficiently in order to provide diverse
Quality of Service (QoS) guarantee for different Class of
Services (CoSs). The Interleaved Polling with Adaptive Cycle
Time (IPACT) [1] is a classic Dynamic Bandwidth Allocation
(DBA) algorithm proposed for the TDM-PON (EPON). It has
also regarded as the performance comparison benchmark by the
most existing EPON-DBA algorithms.
This paper includes the full implementation of the IPACT using
OPNET Modeler [5] and reflects the strong aspects of it as a
traditional EPON DBA which allocates bandwidth by taking into
account the exact need of each Optical Network Unit (ONU) in
every cycle.
