基于 SNMP 的有线电视网管系统在无锡广电的设计与应用

摘要
数字化浪潮对有线电视行业的发展既是一个机遇,但也是一个挑战。
利用 HFC 网络来进行综合业务的传输,对 HFC 网络的可靠性提出了更高
的要求,如何通过监控的技术手段,使其网络和设备提高可靠性,成为
网络运营者越来越关心的问题。安装 HFC 网管系统就是一种十分有效的
技术手段,它能在网络设备万一发生故障时,通过准确、及时的故障定
位,缩短排除故障的时间来增强网络的可维护性。也可预测网络设备状
态发展的趋势,通过做好预先维护来提高 HFC 网络运行的可靠性。
文章简要阐述了有线电视网络管理系统产生的背景及意义以及国内
外网管系统研究现状。同时对网络管理系统、网络管理技术和 SNMP 协议
做了介绍并分析了有线电视管理系统的组成、功能要求等。在此基础上,
完成了符合 HMS 标准的网管应答器的实现。
最后,本文根据阐述了无锡广电选取 TNCS 网管程序实现 HFC 网络管
理的系统设计与实现方案,旨在提供一个全面的 HFC 网络管理方案。

DESIGN AND IMPLEMENTATION IN WUXI BROADCAST OF
SNMP-BASED WORK MANAGEMENT SYSTEM

ABSTRACT

Digitization is not only a chance but also a challenge for the cable TV
industry. To transmit integrated service by work, higher level HFC
network reliability is requested. es as a more important issue that how
to enhance the reliability work & equipment by monitoring technique. It
is a very effective method to install the work monitoring system. The
system is able to fix any problem work equipments timely and
accurately and reduce the time of solving the issue, which enhances the
network maintainability. In addition, it is also an efficient way to enhance
work reliability by forecasting the status work equipments and
doing preventive maintenance accordingly.
The thesis briefly elaborates the background, significance and research
status of cable work management system. It also introduces the
network management system, network management technique & SNMP
protocol, and analyzes the constitution & function of this system. Based on
