运营商视讯业务网络优化方案研究

Research on optimizing scheme of operator’s video service network

目前电信运营商传统固网宽带业务进入发展停滞期,因此运营商均选择大力发展视讯业务,通过视讯业务提升用户的粘度,充分发挥网络富余的流量承载能力,同时通过视讯业务中的增值服务提升效益。但是视讯业务随着用户的逐年增加及内容源的质量提升,运营商数据承载网络面临较大压力。文章通过对运营商数据网网络结构及视讯业务承载特点分析,对网络组播下移改造提出建议,在保证用户提质增速的前提下有效降低网络建设投资。

The traditional fixed-line broadband business of telecommunication operators has formally entered a stagnant period of development.Therefore,operators all choose to vigorously develop video business,enhance the viscosity of users through video business,and give full play to the surplus flow of the network carrying capacity,while enhancing efficiency through value-added services in video services;but with the increase of users and the quality of content sources,operators'data bearing network is facing tremendous pressure.Based on the analysis of the network structure of operators'data network and the bearing characteristics of video services,this paper puts forward some suggestions for the downward transformation of network multicast,and effectively reduces the investment of network construction on the premise of guaranteeing users'quality and growth rate.
