摘要
对于5G网提出的的超大带宽、灵活连接、超低时延、超高精度时间同步、网络切片以及组网结构变化等需求,5G承载网面临着很大的技术挑战。因此根据5G网络的结构变化及关键需求,结合OTN的技术特点,研究了采用OTN技术解决5G网络承载的方案,并提出了5G前传网、中传网以及回传网的解决方案。
5G bearer networks face great technical challenges due to the demands of super-large bandwidth and flexible connection,ultra-low delay,ultra-high precision time synchronization,network slicing and changes in networking structure.According to the structural changes and key requirements of 5G network,combined with the technical characteristics of OTN,this paper studies the solution of 5G network bearer by OTN technology,and puts forward the solutions of 5G fronthaul network,midhaul network and backhaul network.
