To improve the limitations of Ethernet over Coax (EoC) technology in the bidirectional reformation of the hybrid fiber-coaxial (HFC) network, this paper proposes the concept of Ethernet passive electronic network (EPEN) based on multi-point control protocol (MPCP) and the hybrid access scheme of Ethernet passive optical network (EPON) and EPEN. This paper describes the network architecture of EPEN, and introduces the implementation scheme and design of the EPEN system. At present, the project group has been working on the core technology research and key software and hardware design of the EPEN system, on which we have accomplished the hardware design and debugging, the embedded software coding and debugging, the EPEN network management protocol design and software coding. However, there is still a lot to do to achieve networking capability, management, security, quality of service (QoS) and some other functions. |
