Fifth generation networks (5G) have changed the concept of a network as a set of network devices. From the user's point of view, a modern network is considered as a set of services. The underlying technology that allows you to abstract service part of the network from infrastructure and focus on the development of intelligent network services is the technology of software-defined networks (SDN). This technology makes fifth generation networks faster and more flexible, enabling the introduction of services such as enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), and massive machine type communications (mMTC). A convenient mechanism for providing guaranteed quality of network services is the implementation of the concept of network slicing in SDN. Using network slicing network service providers create virtual networks for users with necessary services and quality of service. Network slicing for network service providers opens up the possibility of expanding the range of services offered by leasing several virtual networks based on one physical infrastructure. The aim of the work is a scientific and analytical study of the design features of networks architectures with support for network slicing as well as the development of mathematical and software tools for implementing network slicing in SDN.
Key words: software defined networks, network function virtualization, network slicing, network architecture, software toolkit, SDN Cluster Constructor, quality of service.
