ABSTRACT：
Cloud services are exploding, and organizations are converging their data centers in order to take advantage of the predictability, continuity, and quality of service delivered by virtualization technologies（利用虚拟化技术提供的可预测性、连续性和服务质量）. In parallel（并行的、同时）, energy-efficient（能源有效、节能） and high-security networking is of increasing importance. Network operators, and service and product providers require a new network solution to efficiently tackle the increasing demands of this changing network landscape（环境）. Softwaredefined networking has emerged as an efficient network technology capable of supporting the dynamic nature of future network functions and intelligent applications（支持未来网络功能和智能应用的动态特性） while lowering operating costs through simplified hardware, software, and management. In this article, the question of how to achieve a successful carrier grade network（载波级网络） with software-defined networking is raised. Specific focus is placed on the challenges of network performance, scalability, security, and interoperability with the proposal of potential solution directions（潜在问题的解决方案）.
