摘　　要：传统网络架构面临着结构封闭僵化、数据传输转发性能高度受限以及资源利用率低等问题,使其不能满足未来多样化的服务需求。为了解决这个问题,引入了网络切片的概念,并将网络功能虚拟化(NFV)与软件定义网络(SDN)等前沿技术相互融合在一起,提出了一个面向未来移动通信的新型网络架构——基于SDN与NFV的网络切片架构。这种新的网络架构能够根据第三方需求来为用户提供个性化的网络服务,实现网络资源的共享和隔离,节省了运营商的在基础设备方面的大量花费。The traditional network architecture has some problems such as closed rigid structure, highly restricted data forwarding performance, and low utilization rate of resources, which can ＇t meet the diverse services＇ requirements. In order to solve these problems, the concept of network slice was introduced. A novel network architecture for future mobile communication was proposed, which is based on network function virtualization（NFV）and software defined networking（SDN）. This new network architecture can provide personalized network services to users based on third-party needs,share and isolate of network resources, the cost of a large number of operators was saved in terms of infrastructure.
