最近发布的5G标准承诺为多样化的用户需求提供全面的服务。5G带来的新挑战(例如超低延迟通信)促使功能部署从网络核心转移到边缘。此外，快速变化的业务对服务质量保证的各种要求使得网络功能虚拟化(NFV)成为边缘网络演进的重要使能。到目前为止，新创建的支持NFV的虚拟网络边缘的性能挑战仍未得到探索。本文研究了5G时代融合的虚拟无线接入网(RAN)和移动边缘计算(MEC)。我们首先概述独唱虚拟RAN的表演。然后，我们描述了商用现成(COTS)边缘平台上的Colco-Cate工作负载(RAN和MEC、RAN和RAN)的特征。最后，我们对传统RAN和虚拟RAN进行了简单的成本比较。虚拟RAN系统的应用将有助于未来EDGE NFV的设计。
The recent issued 5G standard promises a comprehen-sive service provisioning for diverse user demands. The new challenges posed by 5G (e.g. the ultra-low latency commu-nication) urge the functionality deployment to offload from network core to edge. Besides, the various requirements of QoS guarantee cast by fast-varying services make the Net-work Function Virtualization (NFV) an essential enabler of edge network evolution. To date, the performance challeng-es at the newly created NFV-enabled virtual network edge are still unexplored. In this paper, we investigate the con-verged virtual Radio Access Network (RAN) and Mobile Edge Computing (MEC) in 5G era. We first outline the solo virtual RAN performance. We then characterize the collo-cate workloads (RAN and MEC, RAN and RAN) on the commercial off-the-shelf (COTS) edge platform. Finally, we provide brief cost comparison between traditional RAN and virtual RAN. The implications of the virtual RAN system will benefit future edge NFV design.
