Abstract
In this paper we address an issue referred to as “over-granting problem”, which is inherent in the existing dynamic bandwidth allocation algorithms for Ethernet-based Passive Optical Networks (EPON), in particular when deployed for multi-threaded scheme in long-reach scenario. In order to solve this problem we design a scheme for the algorithm of Interleaved Polling with Adapted Cycle Time (IPACT) with the limited service discipline. We evaluate the proposed scheme through simulations for single-thread and double-thread cases and demonstrate that, the network performance can be significantly improved by our solution in terms of average delay, jitter, and throughput.

Notes
It is important to note that the proposed type of solution may be difficult to extend to offline DBA schemes; which require the OLT to receive all the Report messages at the end of a cycle.
