# Customer-Oriented Quality of Service Management Method for the Future Intent-Based Networking
## 1 Introduction
Striving to improve the customer's impression of the quality of service received in accordance with the customer's needs, the provider is forced to maintain a balance between the quality of perception and the economic benefits received from these services [17]. The task of traffic distribution becomes the most critical in the case of access to information resources in the network with low bandwidth of the common communication channel. As a result, taking into account the growth of use of telecommunication services and the appearance of new network services on the Internet, the task of developing and implementing traffic management methods, which provide the best QoE of network customers with observance of necessary QoS, is set before providers most sharply [18]. It is difficult to solve the whole range of tasks of adaptive automatic data flow management in conditions of changes in the importance of customers' business processes by using existing methods and network technologies. Since changing the criteria of optimality of management solutions requires constant expert and administrative intervention, in most cases, this leads to significant operational errors, time, and financial costs to their solution. The main problem of the majority of info-communication networks is that they lack complex mechanisms to automate the process of network management and quality of service in real time mode of operation. Intent-Based Networking (IBN) is the beginning of a new era in the history of network technologies and is an evolution of modern intellectual networks [19]. The main principle can be formulated as follows: the network independently transforms the business intentions of customers into appropriate network configurations for all devices [20]. The volume of manual work is reduced to a minimum. In addition, the IBN technology includes a mechanism for continuous monitoring with automatic reconfiguration for consistency with given intentions, which provides an additional level of network monitoring [21]. The basis of this mechanism is a feedback system covering policy-based automation, network analytics, and training [22]. These networks provide a significantly new level of automation, improving service efficiency, speed of innovation, and network reliability. The concept of Intent-Based Networking (Figure 2) is still at the initial stage of its practical implementation. Cisco is actively working on it and has already implemented some of the existing developments in commercially available products. Thus, the evolutionary development of social and economic processes and information technologies determines the relevance of our work, namely the development of an adaptive customer-oriented quality of service management method in a multi-service telecommunications network by monitoring QoS parameters, prioritizing according to QoE requirements, and load-balanced routing mechanisms for the implementation of future IBNs. This paper is organized as follows. Section 2 describes the related research work on the functioning of the traditional quality of service management method based on SLA and the future quality of

Then, Section 3 introduces the proposed customer-oriented quality of service management method for future intent-based networking and developing a network simulation model. Section 4 describes the effectiveness of the proposed solutions using a created simulation model, which allows testing of the traditional QoS management method and proposed customer-oriented QoS management method based on the ordered QoE score. Section 5 discusses the results and how they can be interpreted in the future compared to previous studies and working hypotheses. Finally, Section 6 concludes this work.
