无线网络虚拟化和信息中心网络 (ICN) 是软件定义 5G 移动无线网络中两种有前途的技术。传统上，这两种技术是分开解决的。在本文中，我们表明将无线网络虚拟化与 ICN 技术集成可以显着提高端到端网络性能。特别是，我们提出了一种以信息为中心的无线网络虚拟化架构，用于将无线网络虚拟化与ICN集成。我们开发了该架构的关键组件：无线电频谱资源、无线网络基础设施、虚拟资源（包括内容级切片、网络级切片和流级切片）以及以信息为中心的无线虚拟化控制器。然后，我们将虚拟资源分配和网络内缓存策略制定为优化问题，在我们提出的以信息为中心的无线网络虚拟化架构中不仅考虑虚拟化的增益，还考虑网络内缓存的增益。获得的仿真结果表明，我们提出的以信息为中心的无线网络虚拟化架构和相关方案明显优于其他现有方案。
Wireless network virtualization and information-centric networking (ICN) are two promising techniques in software-defined 5G mobile wireless networks. Traditionally, these two technologies have been addressed separately. In this paper we show that integrating wireless network virtualization with ICN techniques can significantly improve the end-to-end network performance. In particular, we propose an information- centric wireless network virtualization architecture for integrating wireless network virtualization with ICN. We develop the key components of this architecture: radio spectrum resource, wireless network infrastructure, virtual resources (including content-level slicing, network-level slicing, and flow-level slicing), and informationcentric wireless virtualization controller. Then we formulate the virtual resource allocation and in-network caching strategy as an optimization problem, considering the gain of not only virtualization but also in-network caching in our proposed information-centric wireless network virtualization architecture. The obtained simulation results show that our proposed information-centric wireless network virtualization architecture and the related schemes significantly outperform the other existing schemes.
