为满足配电边缘计算终端性能的定量分析需求,提出针对配电物联网的边缘计算终端建模与性能分析方法。首先,基于边缘计算终端架构和配电业务处理,分析边缘计算终端资源调用机制、微服务处理和业务时序逻辑对边缘计算终端资源动态配置的影响,完成边缘计算终端的建模。然后,提出资源时序曲线生成方法,并将资源时序曲线作为性能分析的状态表征,从微服务角度解析边缘计算终端资源动态配置的具体过程,构建出边缘计算终端性能定量分析方法。最后,利用仿真软件EdgeCloudSim,结合价格型需求响应案例,基于2个不同的业务时序逻辑分别输出资源时序曲线,并针对资源时序曲线进行性能分析,得到评价边缘计算终端性能的数值依据。
To meet the demand for the quantitative analysis of the performance of the edge computing terminal (ECT) in distribution networks
this paper proposes modeling and performance analysis methods for the ECT of the distribution Internet of Things (IoT). First
based on the architecture of the ECT and the business processing of the distribution network
the impact of the resource invocation mechanism of the ECT
microservice processing
and task sequential logic on the dynamic allocation of ECT resources is analyzed
and the modeling of the ECT is completed. Then
the generation method of resource timing curve is proposed. The resource timing curve is used as a state representation for performance analysis to analyze the specific process of dynamic ECT resource allocation from the microservice perspective. The quantitative analysis method of the ECT performance is constructed. Finally
combined with the price-based demand response case
the simulation software EdgeCloudSim is used to output the resource timing curves based on two different task sequential logics. The performance analysis is performed for the resource timing curves to obtain the numerical basis for evaluating the performance of the ECT.
