TECHNICAL FEATURES OF BUILDING A LI-FI NETWORK USING SDN MANAGEMENT METHODS

The construction of LI-FI wireless access networks using open source platforms offers very good prospects for communication operators. At the same time, it is necessary to develop system models and describe management methods. For this purpose, the paper proposes to use a centralized management system based on SDN principles. Having complete information about the state of network elements allows you to ensure optimal use of network resources, increase throughput and quality of service. Analysis of the principles of building a LI-FI office network using the management level based on SDN principles to reduce interference in cells, increase throughput and quality of service. Analysis of well-known publications devoted to the methods of construction and management of load flows in LI-FI networks using centralized control systems, reducing the level of interference in cells due to the optimal use of network resources. Based on the analysis of the LI-FI network operation process using centralized management systems, limitations were determined and recommendations were developed regarding the order of user service at access points. Building an access network based on Li-Fi technology is a very promising direction for solving the problems of existing wireless access networks based on radio frequency technologies. To manage such a network, it is advisable to use open source SDN platforms, and, in particular, the ONOS operating system. The proposed solutions require the development of mathematical models and methods for the optimal solution of control problems in different operating conditions.
