NETWORK SLICING: A SUBJECT FIELD OVERVIEW

The existing literature explores the numerous benefits of network slicing for modern cellular networks, including optimal resource allocation, maximizing vendor proJit margins, and improving throughput. Despite the tremendous benefits that network staging can bring to increase the data transfer rate i n future-generation wireless networks, the concept has not been precisely conceptualized to ensure its uniform, comprehensive understanding and use. Based on a detailed analysis of 40 network slicing studies and their feasibility, this review provides a modern and concise overview of the use of slicing, in particular how the researchers considered slicing isolation, what aspects of the technology they investigated, and how they planned their research to implement it in modern networks. The subject area of network slicing is mainly implemented in fifth generation networks to expand and optimize services provided to users. The data obtained reveals network slicing as an efficient solution to provide flexibility and scalability in the 5G mobile networks. In addition to outlining the features and benefits of networking, the overview expanded on the concept of slice isolation. In this paper we present a systematic overview of network slicing technology and existing isolation techniques in nodes and networks, especially in the Radio Access Network and the Core Network (RAN and CN) to give a background to standardized methods of calculating an isolation level leading to secure End-to-End (E2E) slices' isolation
