Abstract: The development of new business puts forward higher requirements for network services, in which network's reliability is the basis of services. Segment routing provides important technical support for network services, and it provides reliability improvement by planning multiple candidate paths. Based on the segment routing policy technology, the seamless bidirectional forwarding detection technology is studied. Network fault detection is carried out for the primary candidate path, which improves the fast perception ability of network fault; through the development work in an open source software platform to realize the functional solution, which better meets the requirements of business for network reliability improvement.
Keywords: seamless bidirectional forwarding detection; segment routing policy; FRRouting
