Abstract
Recently, network virtualization technology (NFV) is being studied to reduce network operation cost, mainly in telco companies. Network virtualization technology is a technology that enables software control by abstracting computing, server, and network functions that were formerly hardware-oriented. Network virtualization technology provides the opportunity for small and medium enterprises with technology to compete in the network market, which is now dominated by major network equipment manufacturers, and software companies participate in the hardware-oriented network equipment market, It provides an instrument that can be easily produced. In this paper, we investigated a takeover scheme based on virtualization technology to provide high availability service in NFV environment and measured takeover performance by virtualizing BGP based on virtualization technology.
