Recently many countries have kept studying on the methods of constructing ultra speed networks. Task Force team for IEEE 802.3ah has accomplished the standardization of EPON which is the next generation subscriber access network. EPON doesn't still have the bandwidth wide enough to support the new service which demands high bandwidth. Therefore 10 G EPON is the next generation subscriber access network...
Due to the geographic distribution of its subscribers, Ethernet Passive Optical Networks (EPONs) have typically varying propagation delays between the Optical Network Units (ONUs) and the Optical Line Terminal (OLT). In this paper, we consider EPONs with an offline scheduling framework, which enables Quality-of-Service mechanisms by collecting bandwidth requests from all ONUs before the OLT makes...
In this paper, we propose a QoS-aware class gated DBA algorithm in which the bandwidth is requested/granted on a service class basis. To avoid the monopoly on bandwidth by higher classes, the maximum bandwidth that is allocated to each service class is limited (fairness between service classes). In addition, to avoid the monopoly on bandwidth by particular users, each ONU runs a fairness bandwidth...
Ethernet passive optical network (EPON) has been widely studied in literatures in the past few years. Researchers from all around the world are investigating EPON main challenges and dynamic bandwidth allocation (DBA) problems. This paper, reviews the most recent studies conducted in EPON networks and presents the new proposed DBA schemes. The reviewed schemes are classified according to the main...
