Abstract Reliability and speed are crucial for ensuring robustness in a computer network, which is used for sharing information and resources within a business. The two most recent and important developments in the field of computing are cloud computing and edge computing. In this study, a modern distributed network comprising computers, internet of things (IoT), edge servers, and cloud servers for data transmission was investigated. A distributed network can be modeled as a graph with nodes and arcs, in which each arc represents a transmission line, and each node represents an IoT device, an edge server, or a cloud server. The data are transmitted through these transmission lines which are combined with numerous physical lines such as fiber cables. Therefore, each transmission line has several possible capacities and the capacity of each arc in the distributed network can be regarded as a multistate. Such the distributed network is called a multi-state distributed network (MDN). In an MDN, the data produced by IoT devices are transmitted to the edge servers. After being processed and compressed by the edge servers, the data are then transmitted to the cloud servers for advance computing. The purpose of this study is to first construct a model of a network in order to elucidate the flow relationship among the IoT devices, edge servers, and cloud servers and subsequently develop an algorithm to evaluate network reliability, which is the probability of the data being successfully processed by the MDN.

具有边缘计算的分布式网络的网络可靠性评估

摘要 可靠性和速度对于确保计算机网络的稳健性至关重要,计算机网络用于在企业内共享信息和资源。计算领域最近和最重要的两个发展是云计算和边缘计算。在这项研究中,研究了由计算机、物联网 (IoT)、边缘服务器和用于数据传输的云服务器组成的现代分布式网络。分布式网络可以被建模为具有节点和弧的图形,其中每个弧代表一条传输线,每个节点代表一个物联网设备、边缘服务器或云服务器。数据通过这些传输线传输,这些传输线与许多物理线路(如光缆)相结合。所以,每条输电线路都有几种可能的容量,分布式网络中每条弧的容量可视为一个多态。这种分布式网络称为多态分布式网络(MDN)。在 MDN 中,物联网设备产生的数据被传输到边缘服务器。数据经过边缘服务器处理和压缩后,传输到云服务器进行高级计算。本研究的目的是首先构建一个网络模型,以阐明物联网设备、边缘服务器和云服务器之间的流量关系,然后开发一种评估网络可靠性的算法,即数据被传输的概率。 MDN 成功处理。这种分布式网络称为多态分布式网络(MDN)。在 MDN 中,物联网设备产生的数据被传输到边缘服务器。数据经过边缘服务器处理和压缩后,传输到云服务器进行高级计算。本研究的目的是首先构建一个网络模型,以阐明物联网设备、边缘服务器和云服务器之间的流量关系,然后开发一种评估网络可靠性的算法,即数据被传输的概率。 MDN 成功处理。这种分布式网络称为多态分布式网络(MDN)。在 MDN 中,物联网设备产生的数据被传输到边缘服务器。数据经过边缘服务器处理和压缩后,传输到云服务器进行高级计算。本研究的目的是首先构建一个网络模型,以阐明物联网设备、边缘服务器和云服务器之间的流量关系,然后开发一种评估网络可靠性的算法,即数据被传输的概率。 MDN 成功处理。
