面向高流量家宽业务的接入网演进策略研究

Research on the evolutional strategy of access network for high traffic service

随着高清网络电视、3D视频等新兴业务的发展,用户对接入带宽的需求越来越高。针对高流量业务对接入网的需求变化,本文分析了现网存在的问题,测算了不同场景下接入网的承载能力,提出应对宽带提速的接入网络演进策略:OLT下行策略和OLT上联部署策略。本文所提策略能够有效指导运营商在面对用户流量高增长的形势下及时调整接入网络结构,为用户提供更好的网络体验。

With the development of high-definition TV, 3D video and other high traffic services, the access bandwidth demand increase day by day. The problems of the present network were analyzed. Based on the estimate of the carrying capability in the access network under different scenarios, simple evolution strategies of access network, OLT downlink strategy and OLT uplink deployment strategy were proposed. The proposed strategies will play an important role in the next access network.
