5G NSA接入专线方案探讨

Discussion on Several 5G NSA Access Private Line Schemes

利用5G大带宽、低时延的网络特性,从现有NSA网络入手,探索利用5G无线网络、核心网、传输网、移动边缘计算实现5G入云专线接入,将专线由传统固定网络接入拓展为5G无线接入方式。基于当前运营商的网络架构,实现了在不同网络层次对专线流量进行解析分流,并通过对比不同方案下专线流量的传输带宽、时延等服务指标,分析了影响业务性能的因素,为现有专线业务发展提供借鉴。

Based on the network characteristics of 5G with large bandwidth and low delay,starting from the current NSA network situation,it explores the use of 5G wireless network,core network,transmission network and mobile edge computing to realize 5G private line access the cloud,and expand the private line from traditional fixed network access to 5G wireless access mode.Based on the current network architecture of operators,it describes several schemes that realize the analysis and diversion of private line traffic at different network levels.By comparing the transmission bandwidth,delay and other service indicators of private line traffic under those several schemes,it analyzes the practical factors affecting the service performance,and provides reference for the development of existing private line services.
