A novel high utilization idle time free dynamic bandwidth allocation algorithm in EPON

Abstract

Ethernet Passive Optical Network (EPON) is a significant solution in the access layer of network that can provide large amount of bandwidth for different kind of traffic. Idle time in EPON is one of the challenges that could decrease the utilization of EPON channel. To decrease or remove the idle time in EPON network several dynamic bandwidth allocation algorithms have been proposed. Some of the proposed algorithms cannot remove the idle time efficiently in some cases. In this paper a dynamic bandwidth allocation algorithm in EPON has been proposed that efficiently removes the idle time. The proposed algorithm has not any additional cost and increases the channel utilization. The simulation results show the validity and effectiveness of the proposed algorithm.
