Abstract
Implementations are directed to designing a redundant configuration for a virtualized network function with cost efficiency while improving reliability of entire service chain. A service chain design apparatus includes a redundancy target VNF determining unit that defines, as importance of each VNF, at least one of the number of service chains using the VNF or the number of accommodated users in the service chains using the VNF, and determines a VNF having high importance as a redundancy target VNF, and a redundancy determining unit that determines, when importance of the redundancy target VNF determined by the redundancy target VNF determining unit exceeds a predetermined threshold, the redundancy target VNF having the importance exceeding the predetermined threshold as a redundancy execution VNF.
