最近，网络功能虚拟化（NFV）被提出作为电信行业的范式转变。工业界和学术界都对移动的网络虚拟化给予了极大的关注。NFV将网络功能的软件实现从底层硬件中分离出来，从而大大降低了运营费用（OPEX）和资本费用（CAPEX），并促进了网络部署。然而，作为一项新兴技术，NFV在开发新架构、应用和部署方面既带来了挑战，也带来了机遇。本文首先综述了NFV的相关工作，然后提出了该领域有前途的研究方向。
Recently, network function virtualization (NFV) was proposed as a paradigm shift in the telecommunication industry. Both industry and academia have drawn significant attention in mobile network virtualization. NFV decouples the software implementation of network functions from the underlying hardware, leading to considerable reductions in operating expenses (OPEX) and capital expenses (CAPEX), and facilitating the network deployment. However, as an emerging technology, NFV brings both challenges and opportunities in developing new architectures, applying and deployment. In this paper, we first survey the related work of NFV, and then propose promising research directions in this area.
