摘　　要：阐述了运营商网络重构的意义和目标，提出了以软件定义网络（SDN）、网络功能虚拟化（NFV）和云计算为核心技术开展网络架构重构工作的观点，其中SDN主要解决网络智能控制和能力开放的问题；NFV重点在网络功能和网元形态两方面着手降低资本性支出（CAPEX）和运营成本（OPEX）；云计算则更多作为基础设施成为网络虚拟化和云化的前提。聚焦运营商需求，SDN技术中需要关注南北向接口和控制器等的标准化；NFV技术中需要关注管理和编排（MANO）规范和统一化网络功能虚拟化基础设施（NFVI）；云计算需要关注虚拟化和开源技术。In this paper, the value and target of the network reconstruction project for operators are demonstrated. It is proposed that key technologies in this project should be soft-defined network (SDN), network function virtualization (NFV) and cloud computing. SDN can provide the network intelligence control and ability openness, and NFV can reduce the capital expense (CAPEX) and operating expense (OPEX) both in network function and element type; cloud computing is the infrastructure of the virtualization of the telecom network. SDN needs to focus on the standardization of the north/south interface and the controller; NFV needs to pay attention to the management and orchestration (MANO) specification and the unified network functions virtualization infrastructure (NFVI); cloud computing needs to focus on virtualization and open source technology.
