Dynamic Allocation with Bandwidth Guaranteed over Ethernet PON

Ethernet Passive Optical Network (EPON) is constituted by Ethernet in the First Mile (EFM), with data encapsulated in Ethernet frames. But the lack of bandwidth allocation and guarantee will be the fatal problem of EPON. We propose a dynamic allocation with bandwidth guaranteed (DABG) method which based on fix slot time and dynamic repartition surplus bandwidth to support bandwidth guaranteed for every Optical Network Unit (ONU). We then analyze the performance under varying offered loads to verify average packet delay, bandwidth satisfaction, and queue size utilization.
