摘要

5G在业务场景、接入网、核心网等多个方面将发生显著变化，对承载网提出了“更大带宽、超低时延、高可靠性”的要求以及网络切片、灵活组网等新需求。结合STN架构，分析了STN的SRv6、FlexE、随流检测、智能管控等关键技术，并对STN和SPN进行对比分析，给出了STN 5G业务具体承载方案，满足了5G 2B和5G 2C业务差异化承载。

Abstract

5G will have significant changes in business scenarios

access network

core network and other aspects.It puts forward the requirements of “larger bandwidth

ultra-low delay and high reliability” for bearer network

as well as new requirements for network slicing and flexible networking.Combined with the STN architecture

the key technologies of STN were analyzed

such as SRv6

FlexE

flow detection

intelligent control

etc.

and the STN and SPN were compared

and the specific bearing scheme of STN 5G service was given

which met the differentiated bearing of 5G 2B and 2C services.
