Inter-ONU Scheduling Scheme for QoS Guarantee in 10G EPON

Recently, more and more services need high quality bandwidth. In order to satisfy those services, high-speed networks are needed. The Task Force team of IEEE 802.3ah set a standard as Ethernet Passive Optical Network (EPON) that is a next generation subscriber access network. IEEE 802.3av developed 10G EPON which has 10 times more capacity than EPON to solve the high quality problem. Research on 10G EPON has been conducted by Kramer, but still there were limitations in providing Quality of Service (QoS). Therefore, this paper suggests a Time synchronization method, resource reservation method, and bandwidth allocation method in 10G EPON. The OPNET simulation results show that our proposed ideas can provide enough services in 10G EPON.
