探究网络切片业务性能保障

To explore the performance of network slicing service

针对网络切片的业务性能要求,从5G子切片技术和核心网切片业务性能保障两方面进行研究,认为通过接入网、传输网和核心网的子切片的隔离技术,特别是核心网的逻辑隔离和物理隔离技术能够确保切片独立的网络资源;通过核心网的业务连续性模式和流量分流模式的选取可以保障网络切片需要的性能。

Aiming at the service performance requirements of network slicing,the research is conducted from the aspects of 5G sub-slicing technology and core network slicing service performance guarantee.It is believed that the sub-slice isolation technology of the access network,transmission network and core network,especially the logical isolation and physical isolation technologies of core network can ensure the slicing of independent network resources;the selection of the business continuity mode and traffic distribution mode of the core network can ensure the performance required by the network slicing.
