基于HFC的BIDS网络管理

HFC-Based BIDS Network Management

光缆电缆混合(HFC)网已被广泛地用来传送电视节目,但用它作为接入网来提供宽带交互数据服务(BIDS)却还没几年。文章首先描述基于HFC的BIDS的基本网络结构,然后从网络管理的角度将它同传统的计算机网络—LAN进行了比较,最后提出有效管理基于HFC的数据网所必须注意的一些关键因素。

Although hybrid fiber coaxial (HFC) networks have been in use for delivering television programs to the home, their usage as access networks to provide broadband interactive data services (BIDS) to the home is very recent. This article firstly describes the network infrastructure for the HFC - based BIDS, and then compares it with the traditional computer networks (LAN) from the view of network management. Lastly the article highlights some key factors to manage the HFC - based data networks efficiently.
