Abstract
Network slicing technology, as one of the key technologies in 5G communication networks, meets diverse business needs by providing customized network resources and services. This technology provides an independent, secure, and complete network environment for each slice by logically partitioning network resources, ensuring end-to-end quality assurance of business. The characteristics of network slicing technology lie in its security and isolation, integrity and end-to-end quality assurance, as well as flexibility and customization, which enable it to adapt to various complex and ever-changing business scenarios. In 5G communication network, network slicing technology is widely used in smart cities and intelligent transportation, industrial Internet and industrial automation, Internet of Things and Internet of Vehicles and other fields, providing efficient and reliable network support for these fields. However, in the application process, network slicing technology also faces challenges such as uneven resource allocation, security issues, difficulties in network slicing management, and inability to ensure interoperability. To address these challenges, a series of coping strategies need to be adopted. By using dynamic slicing and resource scheduling, it is possible to ensure the rational allocation and efficient utilization of resources; Implementing identity verification and encryption technologies can improve network security; Building a centralized management platform can improve the management efficiency of network slicing; Implementing decoupling and openness can help improve the flexibility and scalability of the network. Through these strategies, the widespread application and development of network slicing technology in 5G communication networks can be further promoted.
