摘要
网络新技术的发展为5G注入了新的活力,针对5G新定制化网络应用领域及需求,如何构建一张具备灵活切片能力的移动承载网,成为5G承载网建设重中之重。从FlexE技术架构及应用场景等方面进行了深入研究与探索,详细介绍了FlexE接口技术原理与应用,并与FlexE电路交叉技术进行了对比分析,创新性地提出了基于IP/MPLS机制结合FlexE接口技术的STN承载网切片架构,并给出了5G STN承载网采用FlexE接口部署网络切片发展方向与建议,满足推进5G STN承载网切片大规模商用部署。
The development of new network technology injects new vitality into the new generation of communication.In the 5G era,how to build a bearing network with slicing capability has become the top priority of 5G bearing network construction according to the new customized network application fields and requirements.In-depth research and exploration was made from the aspects of FlexE technology architecture and application scenarios,and a comparative analysis was made with FlexE circuit crossing technology.The STN bearer network slice architecture based on IP/MPLS mechanism with FlexE interface technology was conceived.5G STN bearer network was deployed with FlexE and the development direction were proposed.It can meet the requirements of large-scale commercial deployment of 5G STN network slice.
