Abstract
A service chain construction method includes partitioning a service chain in which a virtual distribution-function-group is arranged upstream of a most upstream virtual communication-function-group among virtual communication-function-groups arranged at stages, into sections, based on arrangement positions of the virtual distribution-function-group and a virtual communication-function-group of a terminating type among the virtual communication-function-groups, determining, for each of the sections, a communication route between a most upstream virtual distribution-function-group or the most upstream virtual communication-function-group in a section of the sections and a most downstream virtual communication-function-group or a most downstream virtual distribution-function-group in the section, based on a traffic ratio in the most upstream virtual distribution-function-group, the most downstream virtual distribution-function-group, the most upstream virtual communication-function-group, or the most downstream virtual communication-function-group in the section, and setting the communication route to the virtual distribution-function-group and the virtual communication-function-groups arranged in the service chain, by a processor.
