The distribution of slice service resources in 5G networks

У статті розглядаються модель мережевої інфраструктури для мікро операторів. Пропонується механізм DTBFR, який використовує теорію дерева рішень як основу для прийняття рішення про трафік на основі SDN. Функції, що розгортаються регіональною службою мікро-оператора, можуть ефективно зменшити навантаження на центр обробки даних в Інтернеті і підвищити швидкість розвитку крайової обчислювальної служби в майбутній мережі 5G.The trend of mobile networks 5G is growing with the increase in the number of users and the speed oftransmission. Many operators are turning to small cellular and internal coverage of telecommunication network services. Due to the emergence of software-specific network technologies and virtualization of network functions, the ISP can deploy its networksmore flexibly and dynamically. In addition to changing the model for deploying a wireless mobile network, it also determines the tendency for micro-operators to develop (μO). Communication operators can provide regional network services through public buildings, shopping malls or industrial facilities. In addition, localized network services are provided and bandwidth consumption is reduced. The distributed μO architecture meets the computing requirements for applications, data, and services from the clouddata center to the peripheral network devices or the micro-data center μO. The μO service model is able to reduce network latency in response to applications with a low latency for the future 5G boundary computing environment. This article discusses the design of the micro-operator 5G and proposes a mechanism for redirecting flows based on the decision tree (DTBFR) to redirect traffic flows to neighboring service nodes. The DTBFR mechanism allows different microcontrollers to share network resources and accelerate the development of border computing in the future

Resource Sharing Challenge for Micro Operator Pattern in 5G SDN/NFV Network

To expand the capabilities of their networks, large operators turn to smaller operators for help, which allows serving more users. This is possible because software-defined network technologies and virtualization of network functions are used. However, the distribution of subscriber flows between the micro-operators networks problem arises. Micro- operator networks have limited technical resources. The network resources consumed by the services are unevenly in time distributed. There are situations when the network resources of the operator are not enough. At the same time, service consumers want to receive services at a given level of QoS. For dynamic control of the sufficiency of micro- operator resources, the article proposes the dynamic flow control method. The method algorithm include the stages: the flows and node resources use monitoring, the optimal node load calculation, prediction of exceeding the permissible load value, and automatic live migration. The modelling proposed algorithm results showed that there are no more overloads of the micro operator networks. The level of service delays decreased by 5%

Quality Control of Mobile Communication Management Services in a Hybrid Environment

There is an integration of telecommunication systems and distributed computing environment, resulting in a single hybrid environment for telecommunication services. The hybrid environment has the ability to control the information flow process at each stage and ensure compliance with high quality standards. Providing the quality of service to end-users of communication networks depends on quality control at all stages of the provision of the service. Today, due to the dynamically changing service structure provided to end users, constantly changing requirements for service quality indicators, with increasing traffic volumes, there is a growing need for well-scalable communication systems that meet the needs of end-users, gaining special significance service management systems. In the article the features of quality control service servicing of flows of the mobile communication network are investigated with the use of partial virtualization of network functions. An architectural solution is proposed for organization of service flows in a hybrid environment, which includes a telecommunication communication network and cloud computing resources that provide maintenance of virtualized functions involved in the organization of service flows. The solution for improvement of the PCRF system as well as a number of procedures that allow ensuring quality control of servicing streams as well as controlling the computing resources of a hybrid system, whose work affects the quality of service of service flows of the system, is proposed
