NFV (Network Function Virtualization) is a powerful emerging technique with widespread applicability. In this paper, we propose a creative solution to decouple the strong coupling relationship between VNF (Virtualized Network Function) and VNFM (Virtualized Network Function Manager) in the current NFV practice. Our solution is to design a VNFC (Virtualized Network Function Controller). It can quickly automate the deployment of VNF into the Docker container and can use the improved compression algorithm to achieve fast inter-node migration of VNF. We have experimentally proved that Docker\'s performance can be improved by 3 to 4 times compared with VM and the improved compression algorithm can effectively improve the compression ratio.
Keywords:NFV; VNF; VNFM; VNFC; Docker; Compression Algorithm
