Fault Tolerance Exploration and SDN Implementation for de Bruijn Topology based on betweenness Coefficient

By Artem Volokyta Heorhii Loutskii Oleksandr Honcharenko Oleksii Cherevatenko Volodymyr Rusinov Yurii Kulakov Serhii Tsybulia

DOI:, Pub. Date: 8 Feb. 2024

This article considers the method of analyze potentially vulnerable places during development of topology for fault-tolerant systems based on using betweenness coefficient. Parameters of different topological organizations using De Bruijn code transformation are observed. This method, assessing the risk for possible faults, is proposed for other topological organizations that are analyzed for their fault tolerance and to predict the consequences of simultaneous faults on more significant fragments of this topology.

Extended DragonDeBrujin Topology Synthesis Method

By Artem Volokyta Heorhii Loutskii Pavlo Rehida Artem Kaplunov Bohdan Ivanishchev Oleksandr Honcharenko Dmytro Korenko

DOI:, Pub. Date: 8 Dec. 2022

Scaling high performance computer systems needs increasing the fault tolerance at the design stage of a topology. There are several approaches of designing simple fast routing with fault tolerance. One of effective approach is to ensure fault tolerance at the topology level. This article discusses two methods for optimizing topologies synthesized using Dragonfly and Excess De Brujin. Methods of topology saturation are discusses, which allow to increase the dimension of the system without deterioration of topological characteristics due to the optimization of the synthesis method. Three scaling constraint methods are also proposed to reduce the topology dimension to the desired performance.

Integrated Safety Mechanisms Based on Security Risks Minimization for the Distributed Computer Systems

By Vadym Mukhin Artem Volokyta

DOI:, Pub. Date: 8 Feb. 2013

Today, there are known the basic principles of decision-making on the safety control of distributed computer systems in the face of uncertainty and risk. However, in this area there are no practical methods for the quantitative risk analysis and assessment, taking into account the dynamic changes of security threats, which is typical for distributed computer systems.
In this paper is suggested an approach to assesment and minimization of the security risks, which allows to reduce the potential losses due to the realization of threats, to analyze the dynamics of intrusions into computer systems and to select the effective security tools.
As a result, there is designed the structure of the tools for risk minimization in the distributed computer systems and are formalized the main functions of this structure. Also, in the paper is suggested the assessment of risk factors of the security threats and the probability of the threats realization, which are based on their division into appropriate groups. The proposed tools for security risk minimization allow effectively identify, classify and analyze threats to the security of the distributed computing systems.
