Network slicing is expected to be critical in the deployment of 5G mobile networks and systems. On top of a single physical infrastructure, the technology enables operators to operate several virtual networks. As the 5G commercialization was recently deployed, network function virtualization (NFV) and software-defined networking (SDN) will drive network slicing. In this article, we present an overview of SDN in 5G, and the motivation, role, and market growth of network slicing. We then discuss usage scenarios of SDN in network slicing for 5G. The proposed architecture comprises the three usage scenarios: enhanced mobile broadband (eMBB) provides the support to varying types of services used; ultra-reliable low-latency communications (URLLC) provides a certain class of applications such as higher bandwidth, high definition video streaming, mobile TV, and so on; massive machine type communications (mMTC) throws light on the types of services used to connect huge numbers of devices. Finally, challenges and solutions based on network slicing in 5G are presented.

网络切片在 5G 软件定义网络中的作用:用例和未来方向



预计网络切片对于 5G 移动网络和系统的部署至关重要。在单一物理基础设施之上,该技术使运营商能够运营多个虚拟网络。随着5G商用的近期部署,网络功能虚拟化(NFV)和软件定义网络(SDN)将推动网络切片。在本文中,我们概述了 5G 中的 SDN,以及网络切片的动机、作用和市场增长。然后我们讨论 SDN 在 5G 网络切片中的使用场景。所提出的架构包括三种使用场景:增强型移动宽带(eMBB)为所使用的不同类型的服务提供支持;超可靠低延迟通信(URLLC)提供特定类别的应用,例如更高的带宽、高清视频流、移动电视等;大规模机器类型通信 (mMTC) 揭示了用于连接大量设备的服务类型。最后,提出了5G中基于网络切片的挑战和解决方案。
