云服务呈爆炸式增长，组织正在整合其数据中心，以利用虚拟化技术提供的可预测性、连续性和服务质量。与此同时，高能效和高安全性的网络也越来越重要。网络运营商、服务和产品提供商需要一种新的网络解决方案，以有效地应对不断变化的网络环境所带来的日益增长的需求。软件定义网络已成为一种高效的网络技术，能够支持未来网络功能和智能应用的动态特性，同时通过简化的硬件、软件和管理降低运营成本。本文提出了如何利用软件定义网络实现成功的电信级网络的问题。具体重点放在网络性能，可扩展性，安全性和互操作性的挑战与潜在的解决方案方向的建议。
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. In parallel, energy-efficient 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. Software-defined networking has emerged as an efficient network technology capable of supporting the dynamic nature of future network functions and intelligent applications while lowering operating costs through simplified hardware, software, and management. In this article, the question of how to achieve a successful carrier grade network 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.
