| 摘 要： | 针对5G环境下服务功能链（SFC）端到端时延无法满足时延敏感型应用需求的问题，将传统虚拟网络功能（VNF）拆分成粒度不一的映射单元，提出了基于微服务架构的粒度可变服务功能链映射（VG-SFCM）算法。首先将传统粗粒度的VNF解耦成细粒度的微服务单元，随后通过SFC内冗余微服务单元的合并及SFC间微服务单元的复用，减少微服务单元的实例化，降低SFC的处理时间。仿真结果表明，所提算法在降低平均部署网络成本的同时，其SFC端到端时延相较于传统的映射算法降低了14.81%。

| Abstract: | For the problem that the end-to-end delay of the service function chain (SFC) cannot meet the demand of delay-sensitive applications in 5G environment, a variable granularity service function chain mapping (VG-SFCM) algorithm based on microservice architecture was proposed by splitting the traditional virtualized network function (VNF) into mapping units of varying granularity.Firstly, the traditional coarse-grained VNF was decoupled into fine-grained microservice units, and then the instantiation of microservice units was reduced through the consolidation of redundant microservice units within SFC and the reuse of microservice units between SFC, thus reducing the processing time of SFC.The simulation results show that the algorithm reduces the end-to-end delay of SFC by 14.81% compared to the traditional mapping algorithm while reducing the average deployment network cost. |
