Abstract

Abstract:

slicing packet network (SPN) has become one of the technologies of the mainstream transmission bearer network for 5G services with its technical advantages.Along with the rapid development of 5G services in towns and rural areas and the higher and broader demand for 5G services from various 5G vertical industries, the SPN deployed in urban and county areas in the early stage could no longer fully meet the service demand.To meet the demand for 5G service development in townships and rural areas, SPN need to be considered down to the township level.Based on the development trend of 5G services in townships, the SPN construction conditions were comprehensively considered in townships, combined with SPN architecture, network topology and other conditions, a township SPN architecture model was built and an in-depth analysis of the actual application scenario construction plan was obtained in a local city, providing reference and ideas for the later township SPN construction.

Key words: SPN, capacity calculation, networking architecture
