摘要
A non-transitory storage medium having stored therein a packet relay program for relaying a packet in a first sub-domain among a plurality of sub-domains in a service chain configured across the plurality of sub-domains is provided. The packet relay program causes a computer in the first sub-domain to perform a process. The process includes specifying a transmission destination on a basis of relay information with which identification information indicating a combination of a plurality of service functions included in the service chain, an index indicating an order for applying the service function, and the transmission destination are associated, changing the index included in the packet into a predetermined value when the specified transmission destination is a second sub-domain among the plurality of sub-domains, and transmitting the packet including the identification information included in the packet and the index of the predetermined value to the specified transmission destination.
