Information processing apparatus, and information processing method

An information processing method to be performed by a computer including a processor and a memory,

• wherein the processor
• stores, in the memory, packet identification information that is common to packets included in a packet group that flows through a network including communication devices performing relaying, and information about network function devices selected by the packet group, each of the network function devices being connected to the communication devices via a layer 2 network, performing a predetermined process for a packet and performing input and output of the packet by a same interface,
• sets, based on the information stored in the memory, one of interfaces of the communication devices as a forwarding destination of a packet input to each of the network function devices in such a way that there is no overlap between the network function devices selected by the packet group and in such a way that overlap with another network function device selected by another packet group is allowed, and
• notifies each of the network function devices selected by the packet group of the interface of a communication device set as the forwarding destination.
