摘要
NFV作为5G网络切片的关键技术,是电信核心网的发展趋势。基于NFV基础架构环境对媒体网关进行VNF功能分解和应用部署,制定了系统承载电信级业务稳定性技术指标与分析流程,暴露了业务闪断和资源抢占所导致的媒体录音合成延迟问题,提出了针对底层硬件的分布式部署与负载均衡解决方案,并根据统计得到MG_Core子VNF应用扩容基线,解决了上述问题导致的系统运行稳定性问题,为基于VNF的媒体网关承载电信级业务应用部署提供了参考。
As the key technology of 5G network slicing,NFV is the development trend of Telecom core network.Based on the NFV infrastructure environment,the VNF function decomposition and application deployment of the media gateway are carried out,and the technical indicators and analysis flow of the system carrying telecom level service stability are formulated.This paper exposes the delay of media recording synthesis caused by service flash and resource preemption,and proposes a distributed deployment and load balancing solution for the underlying hardware.According to the statistics,the baseline of MG_Core VNF application expansion baseline is obtained,which solves the problem of system operation stability caused by the above problems,and provides a reference for the deployment of VNF based media gateway carrying telecommunication level service applications.
