Abstract Loop free alternate (LFA) is a routing protection scheme that is currently
deployed in commercial routers. However, LFA cannot handle all single network
component failure scenarios in traditional networks. As Internet service providers have
begun to deploy software defined network (SDN) technology, the Internet will be in a
hybrid SDN network where traditional and SDN devices coexist for a long time.
Therefore, this study aims to deploy the LFA scheme in hybrid SDN network architecture
to handle all possible single network component failure scenarios. First, the deployment
of LFA scheme in a hybrid SDN network is described as a 0-1… More >
