Abstract
A communication system includes an information processing device and a relay device. The relay device stores information identifying a transfer destination device that is a transfer destination of a packet that includes data destined for the information processing device, and relays communication between a first network that includes the transfer destination device and a second network. When the relay device receives, from a transmission source in the second network, a first data packet that includes the data destined for the information processing device, the relay device generates a device index value that is used when the relay device determines the transmission source from among devices included in the second network. The relay device transmits, to the transfer destination device, a second data packet obtained by adding, to the first data packet, the device index value and a network index value that identifies the second network.
