【摘要】：为了分析移动通信在未来几年向5G演进过程对传输尤其是PTN网络的影响,基于无线网向5G发展将产生三种典型应用以及技术发展的特征,探讨了5G发展对传输网络的关键需求:超高带宽需求、低时延需求、网络切片需求和东西向流量需求。基于以上需求,考虑未来面向5G的城域传输PTN网络会逐步向三层下移,架构向大容量、扁平化和灵活组网的方向发展,并且在实验室测试5G吞吐量的基础上,通过建立模型对城域传输网内带宽进行了测算,提出了城域传输网核心层、汇聚层、接入层的演进方向和技术特征。
[Abstract]:In order to analyze the influence of mobile communication evolution to 5G in the next few years on transmission, especially on PTN network, the development of wireless network to 5G will produce three typical applications and the characteristics of technological development.This paper discusses the key requirements of 5G development for transmission network: ultra-high bandwidth demand, low delay demand, network slice demand and east-west traffic demand.Based on the above requirements, it is considered that the 5G oriented metro PTN network will gradually move down to three layers in the future, the architecture will develop towards the direction of large capacity, flat and flexible networking, and on the basis of testing 5G throughput in the laboratory,By establishing a model to calculate the bandwidth of the metropolitan transmission network, the evolution direction and technical characteristics of the core layer, convergence layer and access layer of the metropolitan transmission network are proposed.
