Документ Development of software of e-learning information system synthesis modeling process(Національний технічний університет "Харківський політехнічний інститут", 2018) Donets, V.; Kuchuk, N. G.; Shmatkov, S.The article reflects the results of the study of the created model of the information structure of the system of support. The model allowed to carry out the process of modeling the synthesis of the information system e-learning. A program with a graphical user interface for the synthesis model of the e-learning information system was used for modeling. The program uses the parameters of the hyper convergent base network and the e-learning system as the input. The result of the synthesis is the optimal placement of users, applications and data blocks by the nodes of the base network. This takes into account the capacity of the system's transactions. This optimizes the capacity of nodes. As a result, the effiency support of the e-learning system is increasing. The structure of the hyperconvergent base network e-learning support network is considered as the main factor that affects the quality of the system's requests. Therefore, it is important to analyze the structure when choosing options for building a hyperconvergent base network and its management. The main purpose of the structure analysis is to determine the parameters of the data streams in the network communication channels. The obtained results are necessary for an adequate estimation of network channels and nodes capacity. Data streams form e-learning tasks, which use applications that launch on network nodes and generate network traffic.Документ A mathematical model for managing the distribution of information flows for MPLS-TE networks under critical conditions(Scientific research publishing, 2018) Hani, A.; Mohammad, A.; Mohammad, S.; Ahmed, A.; Shmatkov, S.; Kuchuk, N. G.; Fawaz, K.The optimal load distribution over a set of independent paths for Multi-Protocol Label Switching for Traffic Engineering (MPLS-TE) networks is regarded as important issue; accordingly, this paper has developed a mathematical method of optimal procedures for choosing the shortest path. As a criterion for choosing the number of paths, a composite criterion is used that takes into account several parameters such as total path capacity and maximum path delay. The mathematical analysis of using the developed method is carried out, and the simulation results show that there are a limited number of the most significant routes that can maximize the composite quality of service indicator, which depends on the network connectivity and the amount of the traffic. The developed technological proposals allow increasing the utilization factor of the network by 20%.Документ Resources redistribution method of university e-learning on the hyperconvergent platform(National Aerospace University n. a. N. E. Zhukovsky "KhAI", 2018) Merlak, V.; Kuchuk, N. G.; Shmatkov, S.; Nechausov, A.In this article a method of constructing a graph model of university e-learning functioning process, deployed on a hyperconvergent platform, proposed. The method is based on problems and objectives of the system structure analysis. The created graph considers available e-learning resources.
