随着技术的发展 ,通信网络结构的演进 ,信息通信网络将主要由核心网和接入网组成。接入网建设是当前网络建设上的热点、焦点和难点 ,是实现三网融合的集中点。并且 ,由于核心网趋于简单 ,接入网越来越复杂化 ,接入网的投资将占到网络总投资的 5 0 % ,甚至更高。本文回顾了我国接入网的建设发展历程 ,提出发展宽带接入网要结合我国国情 ,要加强技术标准、质量保障、网络管理、通信安全的研究 ,要进行有效的电信监管 ,要着重开发对宽带业务的应用需求
With the development of technology and the evolution of communication network structure, the information communication network will mainly consist of core network and access network. Access network construction is the current network construction on the hot, the focus and the difficulty is to achieve the convergence of triple play. Moreover, as the core network tends to be simpler and the access network becomes more and more complicated, the access network will account for 50% or more of the total network investment. This article reviews the history of the construction of access network in our country, and puts forward that the development of broadband access network should be based on China’s national conditions, to strengthen the study of technical standards, quality assurance, network management and communication security. To effectively regulate telecommunications, we should focus on the development of Broadband service application needs
