A BGP session takeover method for high availability based on virtualization technique

Recently, the improvement in the data communication networks in terms of availability and reliability is emerging as a critical issue. In this context, the high availability and reliability of routers that control data flow and routing path between networks are being recognized as critical problems. Many methods for providing high availability to minimize the loss cost caused by the failure of a router are being studied. This paper analyzed the takeover method proposed in the previous studies to support the high availability of the BGP protocol, and proposed a BGP session takeover method using the virtualization technique to improve the takeover performance.
