초록

네트워크 슬라이싱 (network slicing)은 네트워크 인프라를 여러 개로 분할하는 기술을 의미한다. 네트워크 슬라이싱은 네트워크 분할에 들어가는 물리적 자원을 최소화하면서, 유연한 네트워크 구성을 가능하게 한다. 이러한 이유로 최근 네트워크 슬라이싱 기술은 대규모 네트워크 환경의 효율적인 관리를 위해 5G 환경에 적합한 형태로 개발 및 도입되었다. 하지만, 5G 환경에서의 네트워크 슬라이싱 연구에 대한 체계적인 분석이 이루어지고 있지 않아 해당 기술에 대한 체계적인 분석이 부족한 실정이다. 이에 본 논문에서는, 5G 네트워크 환경에서의 네트워크 슬라이싱 기술에 대한 비교 분석을 수행함으로써 해당 기술에 대한 통찰을 제공한다. 본 연구의 비교 분석에서는 체계적인 절차를 통해 5G 환경에서의 네트워크 슬라이싱에 대한 13개의 문헌을 식별하고 비교 분석하였다. 분석 결과, 5G 네트워크를 대상으로 자주 사용되는 3가지 네트워크 슬라이싱 기술인 RAN(radio access network) 슬라이싱, CN(core network) 슬라이싱, E2E(end-to-end) 슬라이딩은 확인하였으며, 이러한 기술은 주로 네트워크 서비스 품질 향상과 네트워크 격리를 달성하기 위해 연구되고 있음을 확인했다. 본 비교 분석 연구 결과는 앞으로의 네트워크 슬라이싱 연구 방향과 활용방안으로서 6G 기술 연구에도 기여할 수 있을 것이라고 판단한다.

Network slicing refers to a technology that divides network infrastructure into multiple parts. Network slicing enables flexible network configuration while minimizing the physical resources required for network division. For this reason, network slicing technology has recently been developed and introduced in a form suitable for the 5G environment for efficient management of large-scale network environments. However, systematic analysis of network slicing research in the 5G environment has not been conducted, resulting in a lack of systematic analysis of the technology. Accordingly, in this paper, we provide insight into network slicing technology in the 5G network environment by conducting a comparative analysis of the technology. In this study's comparative analysis, 13 literatures on network slicing in the 5G environment was identified and compared and analyzed through a systematic procedure. As a result of the analysis, three network slicing technologies frequently used for 5G networks were identified: RAN (radio access network) slicing, CN (core network) slicing, and E2E (end-to-end) sliding. These technologies are mainly used for network services. It was confirmed that research is being conducted to achieve quality improvement and network isolation. It is believed that the results of this comparative analysis study can contribute to 6G technology research as a future direction and utilization plan for network slicing research.
