Analysis of modern standard application methods of software-defined network in 5G/IMT-2020
The paper considers the application of SDN technology in 5G / IMT-2020 networks, namely, answers to the questions: What is SDN technology used for in 5G / IMT-2020 networks; How is SDN technology used in 5G / IMT-2020 networks; What is the role of SDN technology in 5G / IMT-2020 networks; What are the functions of SDN technology in 5G / IMT-2020 networks etc. But before that, it describes what SDN is and what 5G / IMT-2020 is. The paper describes and analyzes the methods of using SDN technology in fifth generation networks in terms of the function and role that SDN plays in these networks. Usually in the literature, this information exists in a scattered form, and sometimes some methods of application are either very superficially described, or not described at all, or they are tied to other methods. The aim of the work is to identify and analyze well-established methods of using SDN in 5G / IMT-2020 networks. To identify SDN applications in 5G / IMT-2020 networks, SDN architecture, SDN benefits, overall 5G / IMT-2020 network architecture, 5G / IMT-2020 standards and requirements, network protocols were studied and analyzed 5G / IMT-2020, some existing and future likely 5G / IMT-2020 network services, general concepts of some future networks such as tactile internet, internet skills, model networks, etc. The paper provides a radial diagram of the ways (options) of using SDN in 5G / IMT-2020 and describes each option.
