“…Акцент зміщується від підвищення продуктивності мережі на поліпшення якості сприйняття обслуговування (Quality of Experience, QoE) [1][2][3]. Забезпечення відповідно до намірів користувачів заданого рівня QoE для послуг і додатків стає фундаментальним завданням під час реалізації наскрізного управління ресурсами в концепції мереж, основаних на намірах IBN [4]. IBN відома як розширення концепції Software-Defined Networking [5][6][7].…”

У статті розроблено метод управління якістю сприйняття у програмно-конфігурованих мережах із використанням ідеології IBN. Так звана IBN (Intent-based networking) основана на архітектурі SDN (Software-Defined Network) і являє собою одну із найважливіших нових можливостей мережевої інфраструктури. IBN пропонує мережевим адміністраторам простий спосіб вираження бізнес-цілей, таких як забезпечення необхідного QoE, даючи змогу мережевому програмному забезпеченню автоматично досягати поставлених цілей із забезпечення рівня QoE. У статті описано розроблення і реалізацію системи моніторингу QoE (Quality of Expirience) для майбутніх програмно-конфігурованих мереж на основі намірів (IBSDN), яка поліпшить якість обслуговування кінцевих користувачів і дасть змогу ефективніше використовувати мережеві ресурси. У статті також подано методи вимірювання параметрів програмно-конфігурованої мережі: затримки і втрати пакетів. Здійснено дослідження для оцінювання ефективності запропонованої системи QoE-моніторингу за допомогою генерації аудіо- та відеотрафіку в мережі Mininet.

The rapid development and spread of communication technologies is now becoming a global information revolution. Customers have a need for communication services, which could be flexibly configured in accordance with their Quality of Experience (QoE) requirements. Realizing the close connection between customer experience and profitability, the service provider has been placing more and more attention on customer experience and QoE. The traditional quality of service management method based on SLA (Service Level Agreement) is not sufficient as a means to provide QoE-related contracts between service providers and customers. The current SLA method is mostly limited and focused on technical aspects of QoS (Quality of Service). Furthermore, they do not follow on the network the principles and semantic approach to the QoS specification for a communication service using QoE parameters. In this paper, we propose a customer-oriented quality of service management method for future IBN (Intent-Based Networking). It is based on a new QoE metric on a scale from 1 to 5, which allows one to take into account the commercial value of e-services for customers. Based on this approach, the network configuration and functionality of network equipment automatically changes depending on customer requirements. To implement the new method of service quality management, an algorithm for routing data packets in the network was developed, taking into account the current load of the forecast path. The algorithm of billing system functioning in conditions of customer-oriented quality management in telecommunication networks has been created. To investigate the effectiveness of the proposed method of service quality management with the traditional SLA method, we developed a simulation network model with the implementation of two approaches. By conducting a simulation, it was determined that the proposed method gives an average gain of 2–5 times for the criterion of the number of customers who require high quality of experience of the service.

“…These technologies promise to deliver more flexible networks with fewer problems in heterogeneous devices, which in turn benefit from shorter operating systems, continuous performance optimization, better interoperability and improved QoS [9][10][11]. IBN can do this because it manages network configuration automatically, so it can respond and scale faster than a human [12][13][14][15]. Network virtualization is a new technology that is being considered as part of the IBN concept by Cisco, Arista, Dell, Juniper companies which focuses on the ability to share the physical network infrastructure across multiple virtual networks.…”

A virtual router model with a static and dynamic resource reconfiguration for future internet networking was developed. This technique allows us to create efficient virtual devices with optimal parameters (queue length, queue overflow management discipline, number of serving devices, mode of serving devices) to ensure the required level of quality of service (QoS). An analytical model of a network device with virtual routers is proposed. By means of the mentioned mathematical representation, it is possible to determine the main parameters of the virtual queue system, which are based on the first in, first out (FIFO) algorithm, in order to analyze the efficiency of network resources utilization, as well as to determine the parameters of QoS flows, for a given intensity of packets arrival at the input interface of the network element. In order to research the guaranteed level of QoS in future telecommunications networks, a simulation model of a packet router with resource virtualization was developed. This model will allow designers to choose the optimal parameters of network equipment for the organization of virtual routers, which, in contrast to the existing principle of service, will provide the necessary quality of service provision to end users in the future network. It is shown that the use of standard static network device virtualization technology is not able to fully provide a guaranteed level of QoS to all present flows in the network by the criterion of minimum delay. An approach for dynamic reconfiguration of network device resources for virtual routers has been proposed, which allows more flexible resource management at certain points in time depending on the input load. Based on the results of the study, it is shown that the dynamic virtualization of the network device provides a guaranteed level of QoS for all transmitted flows. Thus, the obtained results confirm the feasibility of using dynamic reconfiguration of network device resources to improve the quality of service for end users.
