SDN和NFV是网络领域的两项重大创新。SDN和NFV的演变显示了这两种范式之间的强大协同作用。最近的研究努力是将SDN和NFV结合起来，以充分利用这两种技术的优势。然而，SDN和NFV的集成具有挑战性，因为涉及的网络元素种类繁多，相互之间的交互也很复杂。在本文中，我们试图通过提供一个称为SDNV的体系结构框架来解决这个具有挑战性的问题。该框架提供了将SDN和NFV的关键原则集成到统一网络架构中的清晰整体愿景，并为在未来网络中结合SDN和NFV的研究工作提供了指导方针。在此框架下，我们还讨论了实现SDN-NFV融合的关键技术挑战，并确定了未来研究的一些重要课题，以期引起研究界对这一新兴领域的兴趣。
SDN and NFV are two significant innovations in networking. The evolution of both SDN and NFV has shown strong synergy between these two paradigms. Recent research efforts have been made toward combining SDN and NFV to fully exploit the advantages of both technologies. However, integrating SDN and NFV is challenging due to the variety of intertwined network elements involved and the complex interaction among them. In this article, we attempt to tackle this challenging problem by presenting an architectural framework called SDNV. This framework offers a clear holistic vision of integrating key principles of both SDN and NFV into unified network architecture, and provides guidelines for synthesizing research efforts toward combining SDN and NFV in future networks. Based on this framework, we also discuss key technical challenges to realizing SDN-NFV integration and identify some important topics for future research, with a hope to arouse the research community's interest in this emerging area.
