最近提出了网络功能虚拟化，以提高网络服务提供的灵活性并减少新服务的营销时间。通过利用虚拟化技术和商业现成的可编程硬件，例如通用服务器，存储和交换机，NFV将网络函数的软件实现从基础硬件中脱离。作为一项新兴技术，NFV为网络运营商带来了一些挑战，例如保证虚拟设备网络性能，其动态实例化和迁移以及其有效的位置。在本文中，我们简要概述了NFV，解释其要求和建筑框架，介绍几种用例，并讨论此新兴研究领域的挑战和未来方向。
Network function virtualization was recently proposed to improve the flexibility of network service provisioning and reduce the time to market of new services. By leveraging virtualization technologies and commercial off-the-shelf programmable hardware, such as general-purpose servers, storage, and switches, NFV decouples the software implementation of network functions from the underlying hardware. As an emerging technology, NFV brings several challenges to network operators, such as the guarantee of network performance for virtual appliances, their dynamic instantiation and migration, and their efficient placement. In this article, we provide a brief overview of NFV, explain its requirements and architectural framework, present several use cases, and discuss the challenges and future directions in this burgeoning research area.
