Abstract

The next-generation 5G mobile network architecture will support the rapid deployment of new, dynamic network services that are capable of responding to current network conditions and demands. Software-defined Networking (SDN), virtualization technologies, and real-time analytics are the core components that will enable an adaptive and responsive 5G network. We present a case study of a real-time communications (RTC) video service that highlights the manner in which the core components (SDN, virtualization, analytics) allow a flexible and elastic 5G network. Because an end-to-end 5G network does not exist today, we construct one using artifacts from the current 4G/LTE network to host our dynamic network enabled RTC service. We identify three main insights from executing our service that could prove beneficial to the 5G network evolution: need for efficient horizontal control, need to limit identifier proliferation, and the existence of control-plane network functions in service network-function graphs.

基于SDN的实时通信(RTC)动态控制:5G端到端业务案例研究
下一代5G移动网络架构将支持能够响应当前网络条件和需求的新型动态网络服务的快速部署。软件定义网络(SDN)、虚拟化技术和实时分析是实现自适应和响应式5G网络的核心组件。我们提出了一个实时通信(RTC)视频服务的案例研究,强调了核心组件(SDN,虚拟化,分析)允许灵活和弹性的5G网络的方式。由于目前还不存在端到端5G网络,因此我们使用当前4G/LTE网络中的工件构建一个网络,以承载我们的动态网络支持RTC服务。我们从执行我们的服务中确定了三个可能证明有利于5G网络演进的主要见解:需要有效的水平控制,需要限制标识符的扩散,以及在业务网络功能图中存在控制平面网络功能。
