Summary:[Problem] An object is to curb a deterioration in quality of service chains at the time of failure while enhancing use efficiency of resources to be used by service chains in a normal state.[Solution] A service chain accommodation device (1) includes an influence coefficient calculation unit (71) that calculates an influence coefficient indicating that an influence at the time of processing failure of a service chain is greater for a VNF located in a subsequent stage of a service chain and a VNF shared among a plurality of service chains, a residual resource calculation unit (72) that corrects an amount of residual resources that can be accommodated for each of the VNFs through which the service chain passes, and an accommodation design unit (73) that assigns a new service chain on the basis of the amount of the residual resources.
