5G时代3类典型场景的业务需求对承载网络在容量、时延和组网灵活性方面提出了更高的要求,同时针对无线网和核心网架构的变化提出了网络切片、增强路由转发功能等要求。首先分析5G的承载需求,重点考虑5G的3类典型业务场景、无线和核心网的架构变化;然后结合现网100GE PTN的实际应用情况,重点围绕容量、时延等维度完成需求与网络现状的对标;最后提出了网络回传、机房配套的演进方案。
The service requirements of the three typical scenarios in the 5G era put forward higher requirements on the capacity
delay and networking flexibility of the bearer network. At the same time
the changes of the wireless network and the core network architecture propose the requirements of network slicing and enhanced routing and forwarding functions. Firstly
the 5G bearer requirements were analyzed
and the 3G typical service scenarios of 5G and the architecture changes of the wireless and core networks were considered. Then
based on the actual application of the 100GE PTN
the benchmarking of the demand and the status quo of the network was completed mainly around dimensions such as capacity
latency
etc. Finally
the evolution plan of network backhaul and computer room supporting was proposed.
