Abstract
The 5G network slicing technology can greatly improve the network transmission efficiency of users and significantly reduce the transmission delay. Network Functions Virtualization (NFV) provides a new solution for more flexible network deployment and more efficient resource integration. The allocation of virtual resources is often realized through the deployment of Service Function Chain (SFC). This paper studies the problem of virtual network resource allocation under 5G network slicing. By designing an efficient SFC deployment model and VFN backup method, the virtual network resource allocation with high reliability and intelligent offload is realized.
