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.
