摘　　要：首先介绍了ICT服务技术架构演变趋势,综合分析了现阶段面向企业和家庭ICT服务的多种实现方式及其面临的问题与挑战;在比较多种实现方式的基础上,提出构建LSN——新型的电信运营商ICT服务技术架构,该技术架构充分利用现有电信运营商的光纤宽带接入网络以及基于云计算、NFV、SDN的多租户云数据中心,通过运用大二层网络技术,将LSN云数据中心、电信光纤接入汇聚网络、CPN有机集成为承载综合ICT服务的网络基础设施架构。最后,阐述了此架构的技术实现方式以及基于此架构可实现的新ICT应用服务场景。After the introduction of the trends of ICT for enterprise and residential subscribers, the problems and challenges of current ICT solutions were also analyzed. Based on comparison between different patterns of ICT solution, LSN （local service node）, a new ICT service oriented architecture was proposed to telecom carriers. The architecture leverages the telecom optical broadband access network, and by using large layer 2 technology, enterprise/residential CPN were integrated inherently with nearby LSN data centers which were built on cloud computing, NFV and SDN technologies. The new infrastructure was composed of CPN, telecom broadband access networks and ISN cloud data centers. The implementation of such an infrastructure was also presented. Some new use cases were presented too, to show the benefits of the new architecture.
