摘要

通信网络正在经历迈向5G的下一个进化阶段。5G网络的设想是提供一个灵活、可扩展、敏捷和可编程的网络平台,在这个平台上,可以在严格的性能界限内部署和管理不同需求的不同业务。为了应对这些挑战,驱动网络的技术及其体系结构正在发生范式转变。正在开发创新的概念和技术,为下一代移动网络提供动力。这一发展的核心是网络功能虚拟化和软件定义网络技术,它们现在被认为是实现5G网络的两个关键技术推动者,并在网络服务的部署和运营方式方面带来了重大变化。对于刚接触SDN和NFV领域的有兴趣的读者,本文将参考5G网络对这两种技术进行概述。最重要的是,它描述了这两种技术如何相互补充,以及它们将如何推动不久的将来的网络。

NFV and SDN—Key Technology Enablers for 5G Networks
Communication networks are undergoing their next evolutionary step toward 5G. The 5G networks are envisioned to provide a flexible, scalable, agile, and programmable network platform over which different services with varying requirements can be deployed and managed within strict performance bounds. In order to address these challenges, a paradigm shift is taking place in the technologies that drive the networks, and thus their architecture. Innovative concepts and techniques are being developed to power the next generation mobile networks. At the heart of this development lie Network Function Virtualization and Software Defined Networking technologies, which are now recognized as being two of the key technology enablers for realizing 5G networks, and which have introduced a major change in the way network services are deployed and operated. For interested readers that are new to the field of SDN and NFV, this paper provides an overview of both these technologies with reference to the 5G networks. Most importantly, it describes how the two technologies complement each other and how they are expected to drive the networks of near future.
