摘要
为了提升园区网络的稳定性,降低因网络单点故障带来的影响,利用计算机网络仿真平台构建基于多协议双机热备三层网络架构的农企园区网架构模型,并结合由可编程逻辑控制器、各类传感器和边缘计算网关组成的农业生产环境监测网络,通过仿真模型进行实时数据传输以验证模型的有效性、可靠性和容错性.实验结果表明该网络架构模型能够有效规避由汇聚层和核心层单点故障引发的网络中断,通过随机多次模拟网络单点设备故障,网络整体自愈平均时间为35.74s,能够保证农业生产环境数据传输的永续性,将虚拟仿真网络架构模型与实体农业生产环境监测网络相结合进行研究验证,大幅度提升模型的仿真程度和验证结果的准确性.
Abstract
To enhance the stability of the park network and minimize the effects of single point network failures,a three-tier network architecture model for agricultural enterprise park network,based on multi-protocol hot standby,was established using a computer network simulation platform.This model is integrated with an agricultural production environment monitoring network consisting of programmable logic controllers,various types of sensors,and edge computing gateways.The model's effectiveness,reliability and fault tolerance are verified through real-time data transmission via the simulation model.Experimental results demonstrated that this network architecture model effectively circumvents network interruptions triggered by single point failures in the convergence layer and core layer.Through multiple random simulations of single point network device failures,the average self-healing time for the network was 35.74 seconds,can ensure the sustainability of data transmission in the agricultural production environment.The combination of the virtual simulation network architecture model and the physical agricultural production environment monitoring network for research verification substantially enhanced the degree of model simulation and the accuracy of verification results.
