Design and implementation of ethernet passive electronic network over coax

To increase the limit of ethernet over coax （EoC） technology in the bidirectional reform of the hybrid fiber coaxial （HFC） network, an ethernet passive electronic network （EPEN） system based on Coax is proposed and experimentally demonstrated in this paper. The proposed EPEN exploits the existing capabilities of the MAC layer in the ethernet passive optical network （EPON） for reduction of cost of the HFC network. As the MPCP （multi-point control protocol） is introduced in the EPEN, bandwidth control and higher efficiency can be achieved. The experimental results exhibit the throughput of system up to 100Mbps, which meet the requirements of HFC network. To improve the performance of EPEN, frequency division multiplexing （FDM） can be used for further increase of the throughput and more hardware processing modules in the future. can be implemented to enhance the capacity     

EPON中支持多种业务的带宽调度方案

提出了一个在EPON上实现多种业务传输的带宽调度方案，借鉴了区分服务的方法，将服务分级并相应地将EPON的上行带宽分为预留带宽、高优先级和低优先级带宽，并采用了不同的分配策略，仿真分析证明，该调度方案能够很好地支持实时性业务和具有高突发性的数据业务。
