软件定义网络和网络功能虚拟化被广泛认为是未来服务提供商网络的两个关键支柱。网络可编程性、开放API和运营自动化带来的显著运营成本节约预期经常被认为是NFV/SDN愿景的主要优势之一。直观地说，NFV/SDN的灵活性和简化价值使业界得出结论，运营费用将下降。本文介绍了典型服务提供商的运营成本，并讨论了NFV/SDN属性如何影响业务等式。根据我们与全球许多服务提供商的互动分析，运营支出变化的驱动因素、变化的方向以及受影响最大的运营支出类别以结构化分析的形式呈现。
Software defined networking and network function virtualization are widely deemed two critical pillars of the future service provider network. The expectation for significant operations cost savings from network programmability, open APIs, and operations automation is frequently mentioned as one of the primary benefits of the NFV/SDN vision. Intuitively, the flexibility and simplification values attributed to NFV/SDN lead the industry to the conclusion that operating expenses will decrease. This article provides a view into the operational costs of a typical service provider and discusses how the NFV/SDN attributes can be expected to influence the business equation. The drivers of OPEX change, the directionality of the change, and the categories of OPEX most affected based on our analysis from interactions with a number of service providers worldwide are presented in a structured analysis.
