摘　　要：对HFC网络进行统一监控和管理是广电运营商提升服务质量和运维效率的必要手段。长期以来,国内基于《HFC网络设备管理系统规范》建设的HFC网管系统普遍存在成本较高、回传信号干扰严重的问题。本文在对传统HFC网管系统架构分析的基础上,提出了基于DOCSIS技术的新型的HFC网管系统架构。该系统架构利用广电网络已有的双向网络基础设施完成HFC光站网管数据的回传,实现对HFC网络设备的管理。该方案结构简单、管理方便、网管数据通道高速稳定。本文所给出的技术方案可以作为HFC网管系统建设的参考,具有现实指导意义。Two-way HFC network is an important foundation for an integrated information service, hosted by radio and television operators, in multi-service network. Unifi ed monitoring and management of HFC network is a necessary method for radio and television operators to improve service quality and efficiency. Based on analysis of traditional HFC network management system architecture, this paper provides a new one based on DOCSIS. The new architecture uses the existing two-way network infrastructure to complete passback of HFC optical station network management data and realize management of HFC network equipment.
