Abstract

In today’s world of information technologies and in the conditions of growing load on computer networks, it is an urgent task to optimize and improve their performance by effective management of resources and latency reduction. Construction of information technology architecture can reduce latency by moving cloud structures to the edge of radio access networks. Edge computing, which involves processing data at the edge of the computer network, reduces latency and improves response time, and using bandwidth at the edge helps reduce bandwidth usage. Pre-fog computing is an important strategy for improving computer networks in the Tactile Internet environment. The aim of this paper is to model the pre-fog computing of a hierarchical edge cloud network, aimed at determining the delay in traffic transmission, optimizing performance, and managing resources. The object of research is a model of a hierarchical network of edge clouds, including edge and pre-fog clusters, fog and cloud computing. The subject of the study is a model of traffic transmission in a hierarchical cloud network to ensure optimal resource management and traffic transmission, taking into account the delay requirements. In this paper, we model a hierarchical edge cloud network, develop a traffic transfer model, and analyze the delay of clusters of the first and second levels of a hierarchical cloud network. The hierarchical edge cloud network is designed to optimize data transmission and resource management. Edge clusters have limited computing capabilities, so they are connected to more powerful pre-fog clusters. In addition, fog computing ensures coordinated interaction between edge clusters across the entire computer network. The traffic transmission model allows achieving the required latency, efficiency, security, and high availability, making it relevant and useful for the Tactile Internet environment. The advantages of the modeled computer network are reduced latency from the data source to the users and reduced risk of network congestion. This provides flexibility in building the network and increases its availability, which meets the requirements of the Tactile Internet.
