Exploration of Reliability Design for Network Function Virtualization

Abstract

Network function virtualization is the extension and optimization of traditional network architecture,which is to realize the virtualization of network functions in the network infrastructure of operators.From the current network function virtualization technology,there are some challenges in the aspects of high availability,reliability,scalability,etc.How to effectively deal with these challenges and improve the reliability of the virtualization system is an important issue faced by the current network function virtualization research.This paper discusses the reliability design of network function virtualization from the aspects of system architecture,security mechanism and service implementation,and hopes to provide reference for the subsequent work.
