A communication system according to an embodiment of the invention comprises: a transmission apparatus and a relay apparatus connected between the transmission apparatus and each of a plurality of reception apparatuses. The relay apparatus comprises a first reception unit, a device list management unit and a first transmission unit. The first reception unit receives, from the plurality of reception apparatuses, the respective pieces of model information thereof. The device list management unit generates, for each of a plurality of pieces of port identification information for identifying the respective ones of ports to which the respective ones of the plurality of reception apparatuses are connected, a respective piece of device list information obtained by associating a respective piece of device identification information for identifying the respective one of the reception apparatuses with a piece of position information related to the position of the relay apparatus. The first transmission unit transmits the pieces of device list information to the transmission apparatus. The transmission apparatus transmits, to the relay apparatus, a command that designates the piece of port identification information corresponding, in the pieces of device list information, to the piece of device identification information of one of the reception apparatuses to be accessed and that also designates the piece of the position information of the relay apparatus.
