光纤同轴混合网是一种发展前景广阔的宽带接入技术，完善的网络管理是保证网络正常营运的基础，也是网络高效稳健运行的关键。该文提出了一种基于简单网络管理协议的光纤同轴混合网网络管理系统的解决方案，其系统包括简单网络管理协议管理站和委托代理两部分，其委托代理通过通用串行接口实现了对设备的本地管理，网络管理站通过SNMP协议和委托代理交换管理信息，从而实现了对设备的远程管理。关 键 词 光纤电缆混合网; 光纤通信; 网络管理; 简单网络管理协议; 网络管理站; 委托代理Abstract The technology of HFC network is far and wide used in broadband access networks. In the HFC networks, full and precise network management is very important for ensuring the network operation, and also it is key of the network working steadily and high effectively. This paper describes a solution of HFC network managing system based upon SNMP, which includes network management platform system and workstation and proxy agent. Through general serial interface, the proxy agent can monitor local equipments, and through SNMP, the network management system exchanges information with the proxy agent, by which way it achieves remote management, and realizes HFC network’s stability and high-efficiency.Key words hybrid fiber coaxial; fiber optic communication; network management platform system; simple network management protocol; network management workstation; proxy agent
