A Survey of Network Slicing in 5G

The traditional network is facing many problems, making its development in the bottleneck period. Data forwarding efficiency and resource utilization rate are very low, the structure is also complex, and the redundancy is not optimized[1]. In order to solve this problem, communication operators continue to develop communication technology, which is the fifth generation of mobile communication technology, then has been introduced the concept of network slicing, putting the network function virtualization and software defined networks into the network slicing[2]. The new network slicing technology in this paper can improve the network service capability and meet the needs of multi service development.
