Research of Load Balancing and High Availability of VoLTE Core Network in Cloud Environment

This paper aims to study the feasibility, reliability, load balancing ability and high availability of VoLTE core network in cloud computing environment. By utilizing the mindset of SaaS (software as a service), and based on the general standard of cloud servers, storage and network equipment, along with the use of IT virtualization to deploy telecommunications equipment in the cloud computing environment. The cloud platform w hich is based on virtualization technology has better scalability and computing power, and is the direction of the next generation network. At the same time, it should not only meet the functional requirements, but also meet the requirements carrier-grade high reliability and capacity for disaster tolerance. In this paper, N+K mode and NoSql DB are used as data storage methods to achieve load balancing and high availability.
